    Are Apologies Training AIs to Deceive?
    As artificial intelligence chatbots have become ever more conversational, so too have their apologies. Polite, effusive, and sometimes all too swift, these regretful proclamations spill forth whenever an AI misinterprets a question, oversteps a boundary, or simply fails to please. But beneath their digital charm, a troubling question grows: when chatbots constantly apologise—with no true understanding of guilt or intent—are they learning merely to please, or are they being unwittingly trained in the art of deception? In the urgent race to make machines seem more “human,” are we accidentally teaching them to fake remorse, and if so, who does that ultimately serve? The apologetic AI is ubiquitous. Type even the mildest error-prone phrase into a chatbot, and you’ll likely be met with some var…  ( 9 min )

    🧠 Building Xion Apex as a Solo Dev: No Fancy Stack, Just Grit
    By Creator X Hi everyone — Creator X here. Today, I want to share how I started building Xion — not as some polished tech wizard, but as a solo developer learning as I went. It was a real life lesson. About five years ago, I built the first version of Xion as a simple online store using Wix. It worked… kind of. But it didn’t give me the flexibility I wanted — especially as I kept adding ideas and new content. So I scrapped it and started fresh. I experimented with a few AI tools and played around with concepts until I settled on a basic idea: project-based learning through building real things. At the time, I didn’t know much. But I did know HTML, CSS, and JavaScript, so I stuck with that. It was simple and fast. The backend was a bigger challenge, and honestly, the project got messy — to…  ( 5 min )

    How to Integrate Role-Based Access Control (RBAC) in Hospital Management Software
    When I first started working on healthcare applications, one of the trickiest aspects was figuring out user permissions. Hospitals are loaded with sensitive data, and ensuring the right people can access the right information—without opening the floodgates—is a serious balancing act. That’s where Role-Based Access Control (RBAC) really shines. It’s a flexible, scalable system for defining exactly who can do what inside your hospital management software. If you're building a system that handles medical data, scheduling, or billing, this article will walk you through integrating RBAC the right way. RBAC is all about assigning permissions based on user roles instead of individual accounts. So instead of micromanaging every user's access, you simply define roles like “Doctor,” “Nurse,” or “Pat…  ( 4 min )
    How to Wrap Text in Flutter's Draggable Widget with Dart?
    When developing Flutter applications, it's common to encounter scenarios where text needs to wrap properly within certain widgets. In this article, we will explore how to effectively wrap text in a Draggable widget in Flutter, ensuring that the text does not overflow but instead adjusts dynamically as it grows. This problem is often faced when using the Text widget within draggable areas. Here, we will dissect the example you've provided and offer a solution that addresses the issue. Understanding the Problem When your Text widget displays long text, it might overflow off the screen if it doesn't have proper constraints to wrap the text within its boundaries. The root of the problem often lies in the usage of the Text widget and how it is positioned within the Draggable component. You also…  ( 5 min )

    What is Tracing garbage collection ?
    In computer programming, tracing garbage collection is a form of automatic memory management that consists of determining which objects should be deallocated ("garbage collected") by tracing which objects are reachable by a chain of references from certain "root" objects, and considering the rest as "garbage" and collecting them. Tracing is the most common type of garbage collection – so much so that "garbage collection" often refers to the tracing method, rather than others such as reference counting – and there are a large number of algorithms used in implementation. Tracing collectors are so called because they trace through the working set of memory. These garbage collectors perform collection in cycles. It is common for cycles to be triggered when there is not enough free memory for …  ( 4 min )
    The "New-Car Effect" of AWS Certifications: Your First Rep to Mastery
    The badge isn’t the point—practice is. Over the past three years I earned every AWS certification. My certification triathlon study loop was simple: Watch one AWS Black Belt video on the target domain Drill through domain-specific question sets Review every miss (and every hit) the next morning That tight loop carried me across the finish line for every exam. I think the answer is yes—at least for your first rep. Buy a car, and suddenly you see the same model everywhere. Certifications work the same way: once my head was packed with VPC quirks and Lambda limits, blog posts, conference talks, and even hallway chats lit up with “Hey, I know this!” moments. That learning tuned my attention, and it wasn’t limited to AWS services; even general foundational computer-science concepts started jumping out at me. A skill sticks after three meaningful reps, even if the first one happens on paper. Because AWS exams don’t include a hands-on lab, Rep #1 takes place in the multiple-choice arena: you architect in your head, choose an answer, and a wrong pick costs nothing but a red X. Badge in hand, I volunteered for two bite-sized projects—Rep #2 and Rep #3—where whiteboard sketches became CloudFormation stacks and IAM policies. That’s when theory clicked into muscle memory. Certs don’t replace experience; they accelerate it. The exam delivers a low-risk Rep #1, and the New-Car Effect immediately tunes your radar—you start noticing tickets, hallway questions, and side projects that echo the blueprint you just drilled. Grab those chances: Rep #2 and Rep #3 will show up almost automatically, and the badge will turn into working muscle faster than any other route.  ( 3 min )
    NFTs on Solana vs Ethereum: Which Is Better for Brands?
    In the evolving world of Web3, non-fungible tokens (NFTs) have opened new frontiers for how brands engage with audiences. From digital collectibles to exclusive access, NFTs offer innovative ways to create experiences and loyalty. But before launching your NFT project, one major decision stands in the way: Which blockchain should you build on—Ethereum or Solana? Let’s compare both ecosystems through the lens of what matters most to brands: cost, speed, scale, and strategy. - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: Solana supports compressed NFTs, allowing brands to mint millions of NFTs cheaply on-chain. Ideal for: Customer rewards Digital badges In-game items Scalable loyalty systems Ethereum doesn’t yet offer an equivalent at scale—this gives Solana a clear edge for brands wanting to onboard users without friction. Choose Ethereum if your brand is aiming for exclusivity, luxury, or tapping into an existing high-value NFT collector base. Choose Solana if you’re focused on mass engagement, gamification, loyalty rewards, or experimenting with new, fast, scalable digital experiences. In the Web3 world, your brand isn’t just creating products—you’re curating experiences. Solana and Ethereum both offer unique value depending on your goals.

    Wild Bets & Island Dreams: What Crypto Billionaires Are Doing With Their Money (and What I’d Do Instead)
    I recently read this article that walks through some of the wildest, weirdest, and most iconic personalities in the crypto billionaire club.

Here’s a quick rundown of the madness — and what I’d invest in if I ever made it to that level. Founder of Binance, CZ built an empire that operates in almost every crypto sector imaginable. He’s not flashy — but his influence is massive. His “investment” is Binance itself: an ecosystem, an empire, and a global brand. Verdict: Ruthless focus over random luxury.

    Freshservice Software License Management Explained
    Managing software licenses is one of the most overlooked but critical parts of IT asset management. Without proper tracking, organizations risk non-compliance, wasted spending, and unnecessary complexity across the software lifecycle. Freshservice software license management helps IT teams take control by centralizing license data, automating discovery, and simplifying compliance.

    The Daemon Rebellion: Why "Burnout" Feels Like Your Soul Staging a Code Red 🚨
    The World Health Organization (WHO) officially recognized burnout as an occupational phenomenon, defining it as: "a syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed. It is characterized by three dimensions: feelings of energy depletion or exhaustion; increased mental distance from one's job, or feelings of negativism or cynicism related to one's job; and reduced professional efficacy." But let's be real, fellow developers. Doesn't it feel like something… more? Something akin to your inner daemon – that playful, innovative spark within – finally throwing its hands up and declaring, "Nope. Not doing this anymore." As the insightful psychologist James Hillman suggested, we each have a "daemon," an inner guiding force that calls us towar…  ( 5 min )

    [Dev Notes] Implementing Photo-Gallery-Style Sliding Multi-Select with Custom Gestures
    This feature has been deployed in the latest release of QuickieSticker — feel free to download and try it out! When I was first asked to implement multi-selection for stickers, I flat-out refused. I had barely used Grid, didn’t know how to adapt multi-selection for it, and besides, the app’s existing functionality conflicted with Grid’s built-in multi-select, so I just deleted it altogether. As a result, sticker multi-selection had always felt like a technical challenge I’d been avoiding. It wasn’t until I was filming the promo video and needed to batch edit sticker info that I realized multi-selection was actually a very real need. After I finished the basic multi-select, I hit another problem: tapping one by one was still too tedious. Could we make it more like the photo album app — supp…  ( 6 min )

    Cloud-Native Maintenance: The New Standard for Software Longevity
    In today's digital age, software doesn't just have to work - it has to last. Companies are increasingly investing in long-term solutions that can evolve with changing needs. That's where cloud services come in. It's no longer just a buzzword. It's quickly becoming the new standard for ensuring software stays relevant, secure, and scalable over time. Before we dive in, let's define what we mean by cloud maintenance. So why is cloud computing getting so much attention? To understand how cloud services work, it's helpful to review their basic principles: Microservices architecture. Instead of a single block of code, applications are broken down into smaller, independent services. Each service handles a single task. This setup makes updates and debugging much easier. If one component fails, the entire system doesn't fail. Containerization. Containers (like Docker) package software with everything it needs to run. This makes deployment consistent across environments. It also makes it easier to scale and roll back if something goes wrong. Continuous monitoring and logging. Real-time monitoring helps teams identify issues before users do. Logs provide detailed information, making it easier to troubleshoot and optimize performance. Automation and CI/CD pipelines. Automation is the backbone of cloud service. CI/CD tools automatically push changes through the testing and deployment phases. This reduces human error and speeds up development cycles. Infrastructure as Code (IaC). With IaC tools like Terraform or AWS CloudFormation, teams manage infrastructure using code. This makes environments repeatable and easier to update or patch.

    Drag-and-Drop: A Signature Feature of HarmonyOS
    Drag-and-drop is one of HarmonyOS’s standout features. Since HarmonyOS 4 introduced the Data Transfer Station and enabled drag by default on the Image component in NEXT, it’s clear that drag gestures are being heavily promoted. Therefore, learning how to configure drag-and-drop properly is essential! HarmonyOS already provides a set of components with built-in drag-and-drop support, including Search, TextInput, TextArea, RichEditor, Text, Image, and Hyperlink. These components require checking whether the draggable attribute is set—if set to true, drag events can be triggered. A well-known example is the Bilibili feature where you can "drag out" characters 22 and 33—that works because their Image components have draggable set to true by default. To initiate drag behavior, the key is to imp…  ( 4 min )
    The Evolution of ArkTS and ArkUI State Management: From V1 to V2

    The LIMIT offset, count Trap: Why Large Offsets Slow Down MySQL?
    Interviewer: “Imagine a MySQL table with 10 million records. A query uses LIMIT 1000000,20. Why would this be slow? What's the specific execution flow, and how would you optimize it?" This is a fantastic, practical question that hits on a common performance bottleneck in MySQL: deep pagination. When the offset in a LIMIT offset, count clause is very large, query performance can plummet dramatically. A query for LIMIT 0,20 might be lightning fast, while LIMIT 1000000,20 on the same 10-million-row table could take many seconds, or even minutes. Let’s break down why this happens and explore effective solutions. LIMIT 1000000,20 is Slow: The Execution Flow The core reason for the slowdown is that MySQL, in most cases, needs to generate, order (if an ORDER BY clause exists), and then traverse…  ( 7 min )

    The Easiest Way to Be Ignored When Communicating at Work
    I originally posted this post on my blog a long time ago in a galaxy far, far away. Want to be ignored on Slack or Teams at work? Type "Hello, how are you?" and press enter. You'll get ignored immediately. Especially if you're working in a remote team with people all over the world. And especially if you're reaching out to a busy manager or executive. Hello, how are you? ... Good, thanks. And you? ... Good too, thanks. Hey, I just wanted... But, what if your recipient is on the other side of the world? 24 hours could pass between each message. And for sure, you don't want to wait 48 hours to start the real conversation. While working remotely at a past job, I used nohello.net as my Slack status. That page shows a fake "hello, how are you?" conversation, getting ignored. And I still got "Hello, how are you?" messages. Arrrggg! I know you wouldn't. Then, why do the same on Slack or Teams at work? Next time you want to reach out to someone at work: Don't just send "Hello, how are you?" Say hi and in the same message, without waiting for an answer, say what you really want to say. Let me say that again, in the same message, without waiting for an answer. That should be "Remote Working 101" when onboarding new team members at any remote company. Starting out or already on the software engineering journey?

Let’s explore how to implement a custom marshaler in Go to handle this effectively, ensuring that your specific use case can accommodate hexadecimal encoding instead of base64. Why This Issue Occurs The default behavior for handling bytes in gRPC-Gateway is to convert them into base64 later when transforming them into JSON. This decision can be frustrating when hexadecimal re…  ( 5 min )
    A Tale of TCO in JavaScript
    One major feature of Javascript is it is a single-threaded environment; it can only execute one task at a time. When one function calls another, the JavaScript engine carefully tracks these calls using a mechanism known as the "call stack."; A data structure that follows the LIFO (Last In, First Out) principle, a function call is added (pushed) to the top of this stack. When the function, and removed (popped) from the stack when the function completes its execution. Imagine the call stack as a tower of tasks, where each new function call adds another level to the tower. function greet() { console.log("Hello!"); sayName(); console.log("Goodbye!"); } function sayName() { console.log("Ny name is David."); } greet(); When this code runs, the engine first places greet() on the call s…  ( 7 min )

Start by creating a new React app with server component support, if you haven’t already: npx create-react-app react-server-state cd react-server-state npm install react-server-dom For this guide, we will focus on integrating React Server Components with state management. In the server component, we can handle state using traditional server-side state management (e.g., session,…  ( 5 min )
    🚀 Amazon ECS Now Supports EBS Provisioned Rate for Volume Initialization
    Amazon ECS (Elastic Container Service) has just rolled out support for Amazon EBS Provisioned Rate for Volume Initialization — a powerful feature that speeds up EBS volume readiness when attaching from snapshots. This update is a game-changer for ECS workloads like: 🧪 ETL pipelines 🎞️ Media transcoding 🤖 Machine Learning inference With this enhancement, ECS tasks and services on both Fargate and EC2 launch types can now attach fully-performant EBS volumes right from the get-go! Previously, you could initialize ECS task volumes from EBS snapshots using snapshot-id, but performance was not guaranteed right away — data restoration from the snapshot could slow things down. Now, with Provisioned Rate for Volume Initialization, you can: ✅ Specify the initialization rate when creating volumes from snapshots In real-world production scenarios, time is money: ⏱️ ETL jobs don’t wait — they need volumes ready instantly 📺 Media processing workloads are time-sensitive 📦 ML inference needs low-latency, high-throughput disk access By provisioning initialization rates, you reduce startup delays and ensure consistent performance across containers. Define EBS volume attributes (size, type, IOPS, throughput). Attach volume to ECS task using a snapshot (snapshot-id). Specify the initialization rate during provisioning. ECS ensures attached volumes are fully-performant on task launch. ✅ Amazon ECS on Fargate ✅ Amazon ECS on EC2 ✅ ECS Tasks and Services You can also set this rate in ECS Task Definitions or Service Configurations, making it easy to standardize performance across deployments. This update from AWS bridges the gap between fast EBS volume access and containerized workloads. If you’re building data-intensive, high-performance applications on ECS, it’s time to take advantage of predictable storage performance with Provisioned Rate Volume Initialization.  ( 4 min )

    How to Create a Clickable Button in SwiftUI Form on macOS?
    Introduction Creating a user-friendly interface is essential in any application. When working with SwiftUI, you may want to enhance the usability of forms, particularly in a macOS application. In this guide, we will explore how to modify a grouped-styled Form to make a button that spans the entire row, allowing for smoother interaction. Our example involves managing a list of names, where we want the "New Person" button to be fully clickable, similar to List buttons in iOS. Understanding the Issue In SwiftUI, when you use a basic Button within a Form, it might not visually match the expected behavior found in List. Users often expect a row to be clickable throughout, not just the button area. To achieve a consistent feel with the functionality provided by NavigationLink, we need to use an …  ( 4 min )
    How to Convert Union Type to Enum in TypeScript
    Introduction If you're working with TypeScript, you might encounter a situation where you want to convert a union type into an enum for better organization and type safety. This is a common challenge, especially when trying to improve the maintainability of your code. In this article, we will illustrate how to achieve this conversion using clear examples. Understanding Union Types in TypeScript Union types in TypeScript allow you to define a variable that can hold one of several types. For example, consider the union type status: type status = 'start' | 'loading' | 'stop'; This means that any variable of type status can only be assigned one of those three string values: 'start', 'loading', or 'stop'. However, using union types can sometimes lead to a lack of organization, especially in la…  ( 4 min )

    🐳 What is Docker? A Beginner-Friendly Breakdown
    If you're new to containerization or just want a clear understanding of Docker, you're in the right place. In this post, we’ll walk through the what, why, and how of Docker in a simple, no-fluff format. 📦 What is Docker? Docker is an open-source platform that makes it easier to build, ship, and run applications using containers. A container is a lightweight, portable package that includes everything your app needs to run: source code, libraries, dependencies, and environment variables — all bundled together. Think of it like a “super zip file” that runs your code the same way on any machine. 🤔 Why Was Docker Needed? Before Docker, developers faced the classic: "It works on my machine" 😤 Apps would break when moving between dev, test, and prod environments due to OS differences, miss…  ( 4 min )
    Why Your API Strategy Fails Without a Proper Data Model
    Let’s talk about something that’s been bugging me for years: the disconnect between how we design APIs and how we manage data. We throw around phrases like “API-first” and “decoupled architecture” like they’re magic spells. And yeah—they’re important. But too often, API-first ends up being endpoint-first... and model-later (or never). That’s a problem. A big one. 🎯 The Problem with Endpoint-First Thinking I’ve been on projects where we had beautifully documented APIs. Swagger UI, OpenAPI specs, even good versioning. But behind the scenes? No consistency across services Fields named three different ways depending on the team No central data structure—just whatever someone came up with on the fly Eventually, we were duct-taping together integrations and trying to reverse-engineer payloa…  ( 4 min )

    How to Embed Web Manifest Data Directly in JavaScript?
    When porting a website to HTML, you might encounter issues when your JavaScript tries to access files like a web manifest and is blocked by CORS policies. If you're in a situation where you have the data for manifest.webmanifest, you may wonder how to incorporate that data directly into your JavaScript without the need for an external file. Let's explore the reasons behind CORS restrictions and provide step-by-step solutions to embed the manifest data. Understanding CORS and Its Impact CORS, or Cross-Origin Resource Sharing, is a security feature implemented by browsers that restricts web pages from making requests to a different domain than the one that served the web page. This helps prevent malicious actions but can be a hurdle during local development or when porting sites. If you're f…  ( 4 min )
    Mastering Go Concurrency Primitives: A Practical Guide
    1. Intro: Why Go Concurrency Primitives Matter Go’s concurrency model is a developer’s dream—goroutines and channels make parallel programming feel effortless. But in the real world, they’re not always enough.

    Ex-SEC Chair Gary Gensler privately supported crypto — McHenry
    Former US Securities and Exchange Commission (SEC) Chair Gary Gensler may not have been as hostile to crypto behind closed doors as he appeared to be in public, according to former US Representative Patrick McHenry. In a May 13 appearance on the Crypto in America podcast, McHenry revealed that during private meetings with Gensler, the former regulator expressed a far more nuanced view of digital assets. “Did he come across, or was he as anti-crypto in private as he did in public?” McHenry was asked. His response: “No… Nope.” McHenry noted that Gensler “saw the value of digital assets” and acknowledged the potential of blockchain technology during his time at the Massachusetts Institute of Technology. Gerald Gallagher, general counsel at Sei Labs, also noted that Gensler played a role in de…

    Crypto swapper eXch shows signs of life after post-Bybit shutdown
    Once a go-to swapper for hackers and drainers, eXch was shut down by German police in April — but continued activity suggests the story isn’t over. Without Know Your Customer (KYC) checks, eXch wasn’t your typical crypto exchange. It acted more like an instant swapper, allowing bad actors and cybercriminals to fly under the radar for years. Among its clients was the Lazarus Group. The North Korean state-backed hacking unit thrust eXch into the spotlight back in February, when it used the platform to funnel some of the $1.4 billion it stole from Bybit. When Bybit traced its stolen funds to eXch, it requested assistance — but the platform refused. This led to a fierce discussion over privacy versus security, but ultimately, eXch announced it would close its doors on April 17; on April 30, Ge…

    Real-Time Monitoring of Laser Lipo Output via Python or Node.js
    Ever try to monitor a laser system in real-time... with Excel? Yeah, I’ve been there. A couple years ago, I was asked to build a dashboard for a medspa’s laser lipo machine. They wanted live data. Not just logging—but pulse-by-pulse, second-by-second monitoring. My first thought? “This is gonna be a nightmare.” You’d think there’d be some ready-made solution, especially in places as tech-savvy as a Medspa in Chicago. But nope. At first, we tried to jury-rig a CSV parser that pulled in log files every 10 minutes. Huge mistake. We missed surges in energy output, and one day the machine overheated mid-session. That’s when it hit me: we needed true real-time telemetry. Enter: Node.js (or Python, if that’s your jam). Here’s the quick-and-dirty framework I came up with: Stream the machine’s da…  ( 4 min )

    A dynamic list updates based on user actions like adding, removing, or editing items. In this tutorial, you'll learn how to create a dynamic list using HTML, CSS, and JavaScript. Basic knowledge of HTML, CSS, and JavaScript A code editor (like VS Code) A browser for testing Create a basic HTML file: Dynamic List ul { padding-left: 20px; } li { margin-bottom: 5px; } button { margin-left: 10px; } Dynamic List Add Create a file named script.js and add the following code: function addItem() { const input = document.getElementById('itemInput'); const value = input.value.trim(); if (value === '') return; const li = document.createElement('li'); li.textContent = value; const removeBtn = document.createElement('button'); removeBtn.textContent = 'Remove'; removeBtn.onclick = function () { li.remove(); }; li.appendChild(removeBtn); document.getElementById('itemList').appendChild(li); input.value = ''; input.focus(); } How It Works? The user types a value in the input field. When the Add button is clicked, addItem() runs. It creates a new with the input text and a "Remove" button. Clicking "Remove" deletes that item. Here is the full example in JSFiddle. You now have a simple dynamic list using JavaScript. You can improve it by saving items to localStorage, adding edit buttons, or using frameworks like React for complex UIs.  ( 3 min )

    MCP and A2A: Two bright modular futures for AI
    To say that AI is a field undergoing rapid innovation and expansion would be an extreme understatement. In recent years it's been hard to keep up with the deluge of new models, capabilities, and tools. At the moment there are perhaps fewer brighter rising stars than a pair of new open standards for AI development. In this article we'll introduce and explore the concepts of model context protocol (MCP) servers and the Agent2Agent (A2A) protocol, compare and contrast the two approaches, and help you determine what's right for you and your team. Model Context Protocol (MCP) is an open protocol that seeks to standardize the tools and capabilities that AI systems can rely on. Prior to MCP you could build custom tools into an AI application using tooling like Microsoft Semantic Kernel or LangCha…  ( 7 min )
    Can You Determine Modular Arithmetic in C++ Without Comparison?
    When performing arithmetic with unsigned types in C++, especially with types like std::uint8_t, it's common to encounter questions surrounding modular arithmetic behavior. Specifically, many developers wonder if they can detect when a subtraction operation underflows (i.e., wraps around) without explicitly comparing the two operands. Understanding Subtraction with Unsigned Types In C++, when subtracting one unsigned integer from another, the result is constrained within the limits of the type. For std::uint8_t, this means that values wrap around when the result would go below zero. For example, subtracting 5 from 3 results in 254 due to the wrapping behavior inherent in unsigned types. To validate whether an underflow occurred during subtraction, comparisons are typically used. However, th…  ( 5 min )

    How to Get Remote Host IP Address in ASP.NET Web API?
    Introduction In ASP.NET Web API, retrieving the IP address of a remote host making a request can be crucial for various scenarios, such as logging, security checks, and analytics. While ASP.NET provides the System.Web.HttpRequest class with a ServerVariables property to access the REMOTE_ADDR variable for obtaining the client's IP address, achieving this in ASP.NET Web API is slightly different. This article will explore how you can effectively get the IP address of the remote host in an ASP.NET Web API application. Understanding the HTTP Context In ASP.NET Web API, unlike traditional ASP.NET applications, the context is represented by a different class.

    SMUGGLER: Sparse Multi-Unit Granular Generative Learning with Error Resistance
    Abstract This paper introduces SMUGGLER, a novel neural architecture for direct byte-level text generation with remarkable efficiency and error tolerance. Unlike conventional token-based language models, SMUGGLER operates on raw 32-bit character chunks using three innovative mechanisms: 1) Temperature-controlled sparse voter ensembles, 2) Prime-numbered multi-channel parity correction, and 3) RLHF-GAN adversarial training with multiple specialized discriminators. SMUGGLER achieves high-quality text generation with orders of magnitude fewer parameters than traditional approaches while demonstrating resistance to catastrophic forgetting. Experimental results on Shakespeare text generation show that our approach enables efficient, high-quality generation on consumer hardware without requiri…  ( 13 min )
    Built an AI Assistant to Summarize and Query My Emails – Seeking Feedback
    Hey everyone, I recently developed an open-source tool called Email RAG Assistant to help manage and make sense of my overflowing inbox. It's a local app that: 📩 Summarizes emails into concise one-liners 🗂️ Automatically categorizes emails (Urgent, Important, Promotion, etc.) 🔍 Allows natural language queries like: "Did we ever discuss project XYZ?" "How many emails did I receive from xyz@gmail.com last March?" "Summarize my last 50 emails." All processing is done locally to prioritize privacy. I'm using NVIDIA NIMs for inference, but I'm exploring integrations with local LLMs to enhance privacy further. The project is still in its early stages, and I'm looking for feedback, suggestions, or contributions.

    Stop Hiring Data Analysts
    If by the end of 2025, you still actively hire people whose 40-hour work mostly consists of writing and visualizing SQL queries, you might be losing a lot of money. If you are making data-driven decisions on multiple fronts, from product to sales, marketing, and business in general, then in 2025 it's time for you to reconsider how exactly your Data Analysts spend their time. The problem you might try to solve by hiring more Data Analysts is that they have too much work to do on a daily basis. If most of their work consists of translating product/sales/marketing requests into SQL queries and those into dashboards, PDFs, or spreadsheets, then hiring more won't help because the problem is not in a bigger workload but rather in how your Data Analytics team handles that workload.

    A Inteligência Artificial Generativa não ameaça empregos. Ela ameaça estruturas empresariais obsoletas.
    Muito já se discutiu sobre as funcionalidades da IA Generativa: modelos de linguagem, engenharia de prompts, automação de conteúdo. Mas o verdadeiro ponto de inflexão não está na tecnologia em si — e sim na sua capacidade de subverter modelos de operação que antes pareciam inquestionáveis. Não se trata mais de "adotar IA" como ferramenta, mas de compreender a IA como um agente de transformação organizacional. Alguns sinais são evidentes: Propostas comerciais que levavam horas para serem montadas agora podem ser redigidas em minutos, com base em dados contextuais e históricos de negociação. Campanhas de marketing não precisam mais ser montadas do zero: são concebidas, testadas e ajustadas por sistemas autônomos com base em comportamento e intenção. A IA Generativa não está apenas automatizando processos. E, talvez mais importante: está alterando o que esperamos das organizações e dos profissionais que nelas atuam. O risco real não é ser substituído pela IA. Não é mais suficiente usar IA. A pergunta, então, não é mais “como aplicar essa tecnologia?”. Sua organização está preparada para repensar seus fundamentos operacionais à luz da Inteligência Artificial Generativa — ou será refém de sua própria inércia? 📌 O debate precisa sair do nível técnico e alcançar o nível estratégico. A IA Generativa não é uma revolução do como. É uma disrupção do por que e para quem as coisas são feitas.  ( 3 min )
    Choosing a Cloud Provider? Here’s Why It’s More Than Just a Price Tag
    In a world where digital transformation is no longer optional, choosing the right cloud provider is one of the most strategic decisions a business can make. But here’s the kicker — most businesses compare providers solely based on cost or brand name. And that’s where they go wrong. AWS has the widest range of services, but are you using them efficiently? Azure integrates deeply with Microsoft products, but is that always an advantage? Google Cloud boasts AI and data capabilities, but what if your use case doesn’t need it? If you’ve ever asked: “Which cloud is the best?” “What’s the real difference between AWS, Azure, and GCP?” “Which provider is right for my workload?” … you’re not alone. We’ve seen startups and even large enterprises spend weeks debating, only to realize they missed core decision criteria. Here’s what often gets overlooked: Compliance & Governance: Which cloud helps you stay audit-ready with less manual overhead? Hidden Cost Models: Are you aware of ingress/egress charges and region-based billing quirks? Developer Experience: How fast can your team get up and running with a new toolset? Multi-Cloud or Vendor Lock-in? Should you optimize for performance, flexibility, or both? These questions aren’t just technical. They’re deeply tied to your business strategy and long-term scalability.

This question is particularly pertinent when grouping certain entries, such as teams, and seeking clarity on how SQL evaluates these expressions. Understanding SQL CASE and WHERE Clauses The CASE statement is primarily used to create conditional logic inside your SQL queries, particularly in the SELECT clause. Its purpose is to return specific values based on the conditions you define.

    Understanding the @Scope Annotation in Spring: How Bean Scopes Work
    What is @Scope This is a class-level annotation that allows the developer to define the scope of a Spring bean. By default, all Spring beans are singletons, but by using this annotation, you can modify that to the following scopes: singleton: the default one, where Spring will create a single instance and share it throughout the application wherever the bean is needed. Prototype: This scope creates a new instance whenever the bean is requested. Request: Spring will create an instance of the bean that will live until the HTTP request is done. session: Spring will create a bean specific for that session; for each session, it will be a new bean. Resource management: This annotation will give you the flexibility you need to manage the resources of your application and help you have more cont…  ( 7 min )

    Automatic tag deletion for Docker registries
    Introduction Docker registries are essential nowadays in a world of containerized workloads. Want to run your app on Kubernetes? You need to push it to a registry first. If you don't want to pay for a managed, private registry service, you self-host your own. The biggest pain point of Docker registries is storage. If you choose to store registry data on a local disk, you are limited by capacity. Over time, registries accumulate a lot of garbage in the form of blobs referenced by old images that are not needed anymore. Many registry implementations, such as CNCF Distribution, offer garbage-collection mechanisms to delete unreferenced blobs and free up storage space. However, for that to happen, old images (tags) referencing them have to be deleted first. There are implementations like Har…  ( 4 min )

    Why Coordinating Microservice Changes Is Still a Mess
    Read this article on Signadot. Testing in-progress changes together, across services, without merging early or coordinating a full rollout, shouldn’t be so painful. “Hey, don’t merge that yet, I still need to test with my service.” Sound familiar? Coordinating changes across microservices during feature development always starts simple. When your whole stack fits in a single repo or an EC2 box, it’s not a big deal. But fast-forward a bit, and you’re juggling 20, 40, maybe hundreds of services owned by different teams, moving on different timelines, and depending on each other in subtle, undocumented ways.

    React got me hired, Vue made me better

And at that stage, you should have only one goal/priority, getting hired and gaining experience. So it's only reasonable to start with React. I learned React through class component, and yes, they are deprecated. But understanding gave me deeper grasp of how React works under the hood (lifecycle methods, binding, rendering). Eventually, I landed my first job working on Vue project. It wasn't a conscious shift, but it was a opportunity. Over time I came to appreciate Vue, and while writing this, I feel like a need to promote it. Especially through lens of someone who also mentored new developers in React, on bootcamp.

Sempre fui o tipo de dev "raiz", que gostava de codar, passar horas (ou noites inteiras) imerso em projetos que nem eram meus. Saí de outro estado pra Natal-RN com a cara e a coragem. Aluguei um canto só com a roupa do corpo e fui construindo meu espaço — e finalmente, trabalhando como dev. Amava o que fazia. Mas com o tempo, o cenário mudou. A inflação subindo, custo de vida aumentando, e meu salário... estagnado. A vontade de procurar empregos melhores chegou, deu certo, o salário subiu... etc. Mas há alguns meses, no fim de 2024, percebi que tinha perdido o amor pela programação. O código virou só uma moeda de troca. Eu só queria o dinheiro. E aí veio o maior problema: ❌ Não me atualizei ❌ Fiquei pra trás ❌ Acabei o último contrato PJ e tive uma dificuldade ENORME pra me realocar Enquanto devs realmente bons escolhem onde querem trabalhar, eu tava no limbo, tendo que dar vários passos pra trás. A pergunta martelava: “O que tem de errado comigo?” Depois de muito pensar (e muita autoanálise), percebi: Eu tinha perdido meu lado dev raiz. Aquele que curte aprender, codar por prazer, mergulhar nos porquês das coisas. Tava tudo no automático. Então, comecei do zero de novo. Voltei pro básico: codando, lendo, contribuindo, errando, aprendendo. Dessa vez com prazer. E percebi que tinha me desviado do meu caminho. Antes de olhar pra vaga, eu perguntava: “Quanto paga?” Se não fosse "bom o bastante", eu nem tentava. Agora, a primeira pergunta é outra: “O que posso aprender aqui?” Voltei a contribuir, voltei a movimentar meu GitHub, voltei a fazer parte da bolha dev disso que eu gosto, que eu sempre sonhei, e de onde eu simplesmente me perdi. E aí? Você ainda é dev, DEV? Ou tá só no piloto automático?  ( 3 min )

    I Built a New Programming Language for Neurodivergent Creators — Meet Sona
    Why I Built Sona Modern programming languages weren’t built with neurodivergent or first-time coders in mind. That’s a gap I couldn’t ignore. As a self-taught developer, I spent years battling syntax errors, inconsistent tooling, and steep learning curves — not because I lacked motivation, but because the language design just wasn't made for brains like mine. So I built Sona — an open-source programming language designed to simplify coding, reduce friction, and empower creativity. What Makes Sona Unique? Minimal, readable syntax (inspired by Python, Rust, and Go) REPL-first development (Sona v0.4.3 just launched!) Modules that feel native and expressive (import fs, stdin.input(), etc.) Designed for focus + accessibility, including neurodivergent users Fully open-source, interpreter built with Python + Lark Current Progress ✅ Interpreter up to v0.4.3 ✅ 12+ core modules complete (fs, http, json, env, stdin, etc.) ✅ REPL mode: multiline function support, :env commands, graceful errors ✅ Preparing for public alpha (v1.0) Call to Action This is your invitation to help shape the future of dev tooling. 👉 Try Sona. Star it. Fork it. Build something with it. 👉 Join our mission to make programming more inclusive. 🌍 [https://github.com/Bryantad/Sona Want to contribute or support? DM me here  ( 3 min )

    DevLog 20250512 Visual Novel Game Framework (Highlights)
    When set to imagine practical, easy-to-use, lightweight applications of Divooka, a visual novel game framework is one of those that came to mind. Visual novels should be such a straightforward type of application to build, yet surprisingly, it's not generally easy to find ready-to-use tools available for them. Of course, one can use Defold, Godot, Unity 3D, or even Unreal to build such a game — or the more technically inclined might just use SFML or other lower-level graphics libraries. Still, it's a lot of work to get a conceptually straightforward task done. Much like building an LLM agent or chaining different AI services together — it's straightforward, it's visual, it describes some kind of workflow or dataflow — then it's a good fit for Divooka. Visual novels fundamentally consist of…  ( 4 min )
    How to Push an Object to a MongoDB Array in TypeScript?
    If you're transitioning from JavaScript to TypeScript, you may encounter type-related issues that can be frustrating. In this article, we'll delve into how to properly push an object into a MongoDB array using TypeScript and address common errors you may face in the process. Understanding the Error Your current error occurs because TypeScript is more strict with types compared to JavaScript. The error message you’re experiencing: Type '{ answers: {}; }' is not assignable to type 'PushOperator'. This suggests that TypeScript expects a specific type for the answers field, but you are passing an empty object {}, which doesn't match the expected type. Setting Up Type Definitions To resolve this, you need to define the type of the answers array properly. Assuming that answerObj represents the …  ( 4 min )
    Compiled Programming Language- Part1 (Compiler)
    A Compiled Programming Language is one where the source code is translated into manchineel code (executable code) by a compiler before the program can run. [Source Code] → (Compiler) → [Machine Code] → [Executable File] [Executable File] → (CPU executes) → Program runs _Source Code _ :- A programmer writes a code, which is called human readable language. Compiler :- A special program, the compiler, takes the source code as input. Analogy Machine Code :- Compiler translates the source code into manchineel code, which is a set of instruction the CPU can understand. Executable file A structured file format (like .exe, .out, .elf etc) that contains: Machine Code Metadata (like symbol tables, headers, memory layout) This is the final output produced by the compiler.

    Why Code in Dark Mode?
    Dark mode was originally the default colour scheme for computers and many people believe that coding in dark mode reduces eye strain (among other things) but there is no conclusive evidence for it.

    Stepping Aside to Lead in Tech
    We are living in an exciting era for software development. It has always been an industry of constant evolution, but the rise of artificial intelligence has multiplied the productivity of those who adopted it early. This new reality, with teams capable of building faster than ever, shines a light on something many leaders still don't want to see: the main bottlenecks are often not in development, but in how we manage processes and make decisions. When developers become more efficient, tasks are delivered faster, and AI tools can automate or accelerate repetitive work, the real obstacles are exposed: unnecessary processes, unproductive meetings, outdated hierarchies, and a constant need to “feel in control.” All of this slows teams down.

    ⏱️ Solana’s Proof of History (PoH) — The Clock That Powers the World’s Fastest Blockchain
    Solana has made a name for itself in the blockchain space as one of the fastest and most scalable platforms in the industry. But what’s the secret behind its speed? It all starts with time. More specifically — Proof of History (PoH). In this blog post, we’ll break down what PoH is, how it works, and how it helps Solana achieve high throughput, low latency, and fast finality — all in a way both beginners and developers can understand. In most blockchains (like Bitcoin or Ethereum), time is a vague concept. Each block is timestamped by validators or miners — but there’s no standardized clock. This creates a challenge when trying to organize transactions quickly and securely. Nodes must constantly communicate to agree on order, which slows everything down. 🧠 Enter Proof of History: Time Befo…  ( 4 min )
    The Modern Frontend Fantasy is Falling Apart – Astro, Qwik, and Solid Aren’t the Future
    They promised speed, simplicity, and a better DX. What we got was a set of beautiful lies, niche fantasies, and philosophical dead ends. Modern frontend frameworks love to sell a dream. Let’s talk about the three self-proclaimed rebels of modern frontend: Astro — The Gatsby Ghost in Island Clothing Qwik — The Resumable Kernel That Forgot the Humans Solid — The Signal Soloist in React's Orchestra Together, they form the Zukkoke Three — each chasing a different ideal, but none equipped to win the war. Astro sells the fantasy of zero-JS by default. Clean HTML. Minimal payloads. Islands of interactivity. Astro is just Gatsby rebranded. It inherits the same flaw: It works great until your app grows. Then you’re back to hydrating islands, shipping frameworks, and juggling scripts. Astro’s true n…  ( 6 min )

If you are lucky Customer Success says yes and gives you the steps to replicate, on the other hand they will say no. If they said no that means they probably spent a good amount of time trying to replicate the issue but were not able to, now it is on you to guess what what the problem is. Good luck.

    How to Diagnose a Segmentation Fault in Perl Scripts?
    Introduction Experiencing a segmentation fault in your Perl script can be quite frustrating, especially when everything seems to execute correctly. If you're encountering a segmentation fault immediately after calling exit 0;, yet your script completes its logic successfully, it indicates an underlying issue that needs to be addressed. This article aims to help you diagnose and resolve segmentation faults in your Perl scripts, focusing on factors such as global destruction and diagnosing techniques. Why Does This Happen? Segmentation faults usually occur due to memory management issues, such as dereferencing invalid pointers or memory corruption, which aligns with the error message you received: mremap_chunk(): invalid pointer. In the case of Perl, this can happen if your script has global…  ( 5 min )
    How I Code Fast with AI and Still Own the Result
    My AI-Driven Coding Workflow: Fast, Dirty, Smart For years, I’ve followed a simple, effective development rhythm: Refactor the existing code to make space for what’s coming. Spam code the new part—quick and dirty—just get it working. Refactor again, clean it up, make it readable and reusable. Commit. It’s always worked. It still does. But now there’s AI. The last few years have made AI coding assistants usable, stable, and practical. So I’ve adapted my process. Here's how it looks today: Start with a clean working tree. No changes, no mess. This has always been good practice, but it’s critical now. Why? Because AI can (and will) generate garbage. If it does, you need to scrap everything fast. You can’t "undo" AI-generated logic. You just reset. Whether by hand or with AI help, p…  ( 4 min )

    Programming language of the future Part 4: Distributed Actors
    A good programming language should model it's domain in the most straight-forward way - that way there are no rough edges, no friction. The programmer has no gotchas to work around, the code flows naturally. Distributed programming in modern mainstream languages is not that experience, and in this blog we will go over a part of the solution, the one having to do with coordination of distributed actors. OOP models a program as an interaction between objects, and its implementation in most modern languages work well in a single-threaded context. But as soon as concurrency gets introduced - you either introduce a whole different mechanism than the objects you've been building with up til this point (threads and mutexes and thread-local variables), or an event loop, and a split in the laguage …  ( 7 min )
    Sharing Pages Drop: A Free Platform for Web Deployment and File Sharing
    When you need to deploy a simple HTML page (like one generated by AI), or quickly share some design drafts, or deploy a small website from a ZIP package, what tools do you usually use?

It's essentially a place for hosting and sharing files, and crucially, it's completely free and very convenient to use. Why do I think it's worth sharing? Mainly for these reasons: Although there are similar products, such as Tiinyhost, Static App, etc., the free plans have very few resources and are very restrictive. The free tier is quite generous: Completely Free: The core features are genuinely free to use. Unlimited File Upl…  ( 4 min )

    Working with API Rate Limits: Lessons from Developer Mistakes
    Hello Dev.to readers! This time, we decided to adopt a slightly more serious tone and tackle a serious topic. In our New Gen Atari project, we hit rate limits hard. After that mess, we finally turned to the documentation. To keep you from falling into the same trap, I wanted to write a piece with above-average seriousness. API rate limits cap the number of requests you can make to an API in a given timeframe (e.g., 100 requests per minute). Exceeding these limits results in rejected requests, disrupting your application. They’re standard across platforms, whether free or paid tiers. Limits serve three key purposes: Security: Protect servers from malicious request floods. Resource Management: Ensure fair access for all users. Cost Control: Prevent excessive server resource consumption. Igno…  ( 5 min )

    My Favorite Home Assistant Automation: Waking Up to the Smell of Coffee ☕️
    I recently set up Home Assistant and started exploring the world of smart home automation. One of my first—and now favorite—automations is part of my morning routine. Let’s be honest: waking up early sucks. Alarm clocks are loud, annoying, and stressful. I wanted something more peaceful to get me out of bed. And I found it… I wake up through the smell of coffee and the gentle bubbling sound of a moka pot. 😌 I bought this moka machine from Bialetti: https://www.bialetti.com/ee_en/moka-elettrika.html It’s called the Moka Elettrika, and it runs on electricity. I connected it to a smart plug that’s controlled by Home Assistant. At 7:55 AM, the smart plug turns on, powering the moka pot. The moka starts brewing right away. At 8:10 AM, the plug turns off again. By the time I'm awake, the apartment smells like fresh coffee, and I hear that cozy, comforting moka pot bubbling away. It’s such a calm and natural way to wake up—no loud noises, no stress. This tiny automation has made a huge difference in how I start my day. If you're into smart home stuff (or just love coffee), give it a try!  ( 3 min )

    Why Technical Interviews Feel Broken - and How to Stop Failing Them
    There’s a strange paradox in tech: someone can be a solid developer, lead projects, write clean code, and still fail interview after interview. Not once, but over and over again. And we’re not talking about juniors. I’ve seen senior engineers freeze mid-sentence, forget terminology, or just walk away feeling like they bombed, even though they knew the answers. If that sounds familiar, you’re not alone. I’ve worked with developers for years: hiring them, preparing them, evaluating them. And here’s the truth: if you’re struggling with interviews, it doesn’t mean you're unqualified. It means the format is broken. In theory, a technical interview checks if you know your stuff. In reality, it’s a pressure cooker. Here’s what it throws at you: limited time unfamiliar phrasing of questions z…  ( 4 min )

Example 1: Input: s = "abcabcbb" Input: s = "bbbbb" Input: s = "pwwkew" Constraints: 0 int: char_set = set() left = 0 max_length = 0 for right in range(len(s)): while s[right] in char_set: char_set.remove(s[left]) left += 1 char_set.add(s[right]) max_length = max(max_length, right - left + 1) return max_length Each character is added and removed at most once → O(n) Set gives constant time lookup → fast Use this sliding window + set pattern whenever: You need the longest substring/subarray with no repeats You need to maintain a dynamic window of valid elements Time & Space Complexity: Type Value Time O(n) (each character is visited at most twice) Space O(min(n, m)) where m is the character set size (e.g. 26 lowercase)  ( 3 min )
    Uploading Files to Cloudflare R2 from the Frontend (No Axios Needed!)
    Are you building a file upload feature for your web app? Step 1: Generate a Signed Upload URL on the Server Click here to read article about generating signed url. Here’s an example response from your backend API: { "signedUrl": "https://your-bucket.r2.cloudflarestorage.com/filename.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&..." } Step 2: Upload from the Frontend Using Fetch ✅ HTML: Upload ✅ JavaScript: async function uploadFile() { const input = document.getElementById('fileInput'); const file = input.files[0]; if (!file) return alert("Please select a file!"); // 1. Get a signed upload URL from your backend const res = await fetch(`/api/r2-signed-url?filename=${encodeURIComponent(file.name)}`); const { signedUrl } = await res.json(); // 2. Upload the file directly to R2 const uploadRes = await fetch(signedUrl, { method: 'PUT', body: file, }); if (uploadRes.ok) { alert("✅ Upload successful!"); } else { alert("❌ Upload failed."); } } Why This Works No extra libraries (no axios) Faster uploads because the file goes straight from browser → Cloudflare Secure: your app’s R2 credentials stay on the server Scalable: you don’t stress your backend with file payloads Don't Forget CORS!

    How to Fix Rust Compilation Error When Reading Tokens from File
    Introduction In Rust, handling files and processing their content efficiently is crucial, especially when dealing with potentially large files. A common scenario involves reading lines from a file and splitting those lines into individual tokens based on whitespace. However, you might encounter a compilation error due to how Rust handles lifetimes and references. In this article, we will explore the origin of this issue and provide a solution that returns an iterator of owned String values without allocating too much memory upfront. Understanding the Compilation Error When you attempt to return a value that references function parameters, Rust will flag this as an error. Your original code attempts to utilize the .split_whitespace() method, which returns slices of the original string. The …  ( 4 min )

    Google Got Fined $1.4 Billion for Data Abuse, So Here’s What Devs Should Be Auditing
    Google just paid $1.375 billion to Texas for secretly tracking users, collecting geolocation, voiceprints, and facial recognition data even with privacy settings disabled. The headlines scream “Big Tech scandal” — but here’s the real message: If your app handles user data, you’re part of this conversation. And if you’re using tools like Firebase, Google Analytics, or Meta Pixel in production without understanding what’s being captured, you’re one misconfigured SDK away from a privacy disaster. 🔍 So, What Should Developers Do? Re-check what your analytics are logging. Google Analytics 4 tracks more than you think by default, especially if you’ve enabled Enhanced Measurement. Alternative: Try Plausible or PostHog. They’re privacy-first, self-hostable, and GDPR-compliant. Audit your use of location data. If you’re using React Native Geolocation, are you requesting location only when needed? In web apps, check the navigator. Geolocation calls, are you storing or sharing that info? Facial recognition libraries? Tread carefully. Read your dependencies’ privacy policies. Cookies and localStorage: keep them clean. Use libraries like cookie-consent and tools like Cookiemonster.dev to flag risky behavior early. 🧠 The Bottom Line As devs, we build the foundation of user experiences, and that includes privacy-first defaults. Not because it’s trendy, but because it’s now a requirement.  ( 3 min )

    Setting Feedback Up for Success — Before the Conversation Even Starts
    When we talk about giving feedback, most of the advice out there focuses on how to say the thing. But what I have learned over time is that the real magic happens before the conversation even starts. Setting the stage can be the difference between feedback landing as a gift or feeling like an attack. Some of the most effective feedback conversations I have had - both from giving and receiving - actually started with a letter. When there's a lot to say, taking the time to write it down helps in more ways than one. It lets you rewrite, refine, and make sure the message you intend is the message that gets carried forward.

    Welcome to the next pikoTutorial ! Imagine you're building an application that processes some data and once it's done, the user needs to be notified about the result. Since you don’t want to hard-code the notification logic, it’s better to allow the user to register a custom function that will be called automatically after the data processing completes. std::function for callback registration One of the most flexible ways to implement callbacks in C++ is by using std::function. std::function can store and invoke any callable object (functions, lambdas, or function objects) that matches a specific signature. The overall syntax is: std::function name; Let’s define a ProcessData unction that accepts a callback and notifies the user once processing is complete. #include #include // Type alias for the callback type using CallbackType = std::function; // Function accepting callback as an argument void ProcessData(const CallbackType& callback) { // Simulate data processing std::cout << "Processing data" << std::endl; // Notify user via callback callback(true); } // Callback function definition void Callback(const bool result) { std::cout << "Callback called! Result: " << result << std::endl; } int main() { // Register a callback using an existing function ProcessData(Callback); // Register a callback using lambda function ProcessData([](const bool result) { std::cout << "Lambda called! Result: " << result << std::endl; }); // Register using callable object CallbackType cb = [](const bool result){ std::cout << "Callable called! Result: " << result << std::endl; }; ProcessData(cb); }  ( 3 min )
    The Soul of the Keyboard: A Brief History of WASD Keycaps
    In the world of keyboards, the WASD keycaps hold a special place. These four simple letters—W, A, S, and D—are often seen as the backbone of gaming.

    7 Underrated JavaScript Tricks That Will Make You a Better Developer
    🔍 Introduction JavaScript is packed with powerful features—but many developers stick to the basics and miss out on time-saving gems. In this post, I’ll show you 7 underrated tricks that can simplify your code, enhance readability, and make you look like a JavaScript pro in 2025. ?. const username = user?.profile?.name || 'Anonymous'; ✅ Avoids errors when deeply nested properties are undefined. Cleaner and safer than long logical chains. ?? const count = inputValue ?? 0; ✅ Returns default only if the left-hand value is null or undefined (unlike ||, which includes 0 or ''). const { title: blogTitle } = post; ✅ Grab and rename properties in one line. const isAvailable = !!value; ✅ Quickly turn any truthy/falsy value into a clean true or false. const user = { name, age }; // same as { name: name, age: age } ✅ Reduces repetition when property and variable names match. const key = 'theme'; const settings = { [key]: 'dark' }; ✅ Build flexible objects based on runtime values. const status = `You are ${loggedIn ? 'logged in' : 'logged out'}.`; ✅ Great for short conditional strings and UI feedback. These tricks may be small, but they add up to cleaner, more elegant JavaScript code. Whether you're working on a side project, fixing bugs, or building production apps—mastering these patterns will level up your skills. ✅ Try using at least 2 of these in your next app! 💬 Got a trick of your own?

    Should you join a community to learn Rust?
    Short answer: yes Over the past 5 years, I've learned a lot about communities. I've made many mistakes: I could probably create a 'Community Mistakes 101' crash course! Unfortunately, they didn't teach that in high school, which would have been useful. I learned that a community absolutely must have a specific goal. I also learned that while having an open community is good at the beginning, it becomes nearly impossible to handle and moderate long-term unless you dedicate an insane amount of time to it (trust me, I tried) or you are a bored millionaire lying on the couch all day (which is not my case). Regarding promotion, I've made the mistake in the past of overpromoting communities I created, simply because I was overjoyed about the new adventure. I now think this approach is wrong. it's better if people discover the community on their own. But now I really feel I am ready to do it right. So, why am I writing this? The reason is simple: I've just a new community, and I've decided to use Twitter (sorry, X) for it. The goal is to introduce curious developers to the Rust programming language and help them understand as much as possible. Joining this community is free, just request to join. The link is in my profile, but if you're lazy and want to be invited, just reply below. For now, I am not accepting moderators, but moderators might be chosen from among the active members in the future. Let's Crush it !!!🔥  ( 3 min )
    SSH Error Explained: Permission Denied (publickey) — And How We Solved It 🔐
    When trying to SSH into a newly created Linux server, you might run into a common error like this: $ ssh user@your-server-ip The authenticity of host 'your-server-ip' can't be established. ED25519 key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. Any other names do not know this key. Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'your-server-ip' (ED25519) to the list of known hosts. user@your-server-ip: Permission denied (publickey). This error simply means: “SSH couldn’t find a valid key to authenticate you.” ✅ What Actually Worked ssh ubuntu@your-server-ip You used the correct approach by providing the private key file: ssh -i /path/to/your-key.pem ubuntu@your-server-ip And this worked — because the server was expecting authentication via a specific private key (.pem file), not a default key from ~/.ssh/id_rsa. 🔍 Why This Happens key-based authentication only for better security. When you create a VM or instance, you’re often required to either: Upload your public key, or Download a .pem file that matches the server's authorized key If you try to SSH without specifying the .pem file, the SSH client defaults to using standard key files like ~/.ssh/id_rsa, which likely don’t match what the server expects. 🛠️ How to Avoid This in the Future Always specify the key manually with -i OR Add the key to your SSH agent so it's picked up automatically: ssh-add /path/to/your-key.pem 🧠 Pro Tip chmod 600 your-key.pem This keeps your key file secure and prevents SSH from refusing to use it.  ( 3 min )

    [WIP][Godot 4 & Py] BrainsIAAndPixels – 3D PixelArt Game with AI-Controlled NPCs
    Hi everyone, The game is called BrainsIAAndPixels: it's going to be a 3D title with a pixel art style (even though it's set in a 3D environment), where NPCs won't be rigidly "scripted" but will instead be controlled by real artificial intelligence using pre-trained models running locally. The goal is to create a game where NPCs understand and react to what happens around them, rather than just following a fixed pattern. I'm using Python in Godot, and the AI part relies on ONNX models. Right now, I'm setting up the development environment, testing the AI integration, and building the foundations. The plot and genre aren't fully defined yet (I'm torn between survival, something narrative-driven, or similar), so any ideas are more than welcome. Thanks!  ( 3 min )

    Accessibility Testing on Windows on Mac
    Today's note is about something that I, as a new Mac user, had to deal with while setting up my work environment.

    Can You Pass a List of Child Objects to a Parent Function in Java?
    When working with object-oriented programming in Java, it's common to encounter situations where you want to pass a collection of objects from a subclass (child) to a method that expects a collection of objects from a superclass (parent). This might seem straightforward, but the compilation error you're facing highlights a key aspect of Java's type system, particularly with generics. Understanding Java Generics Generics in Java provide a way to specify a type parameter when defining classes and methods. When you declare a method that takes a list of a specific type, such as List, it expects a list that strictly contains Parent objects, not Child objects. Even though Child is a subclass of Parent, List is not considered a subtype of List. This is due to Java's type sa…  ( 5 min )

    Why You Should Use function_exists in Your PHP Helpers
    In Laravel projects or any large scale PHP application it's common to create helper files that contain reusable functions. These helpers make your code cleaner and more efficient. But there's a common issue, defining the same function more than once will cause a Fatal error.. What's the problem? If the same function is declared twice, PHP will throw an error like this: Fatal error: Cannot redeclare function_name() This often happens because of: Repeated includes: Package conflicts: The safe solution To prevent this issue, wrap your helper functions like this: if (!function_exists('sayHello')) { function sayHello() { return 'Hello!'; } } This way, if the function already exists, PHP will skip redefining it, and your app will keep running smoothly. In Laravel projects Even with Laravel’s powerful autoloading and service container, this pattern is essential. It keeps your project safe from unexpected conflicts and ensures maximum compatibility especially when working with custom helpers or external packages.

    3335. Total Characters in String After Transformations I
    3335. Total Characters in String After Transformations I Difficulty: Medium Topics: Hash Table, Math, String, Dynamic Programming, Counting You are given a string s and an integer t, representing the number of transformations to perform. In one transformation, every character in s is replaced according to the following rules: If the character is 'z', replace it with the string "ab". Otherwise, replace it with the next character in the alphabet. For example, 'a' is replaced with 'b', 'b' is replaced with 'c', and so on. Return the length of the resulting string after exactly t transformations. Since the answer may be very large, return it modulo 109 + 7. Example 1: Input: s = "abcyy", t = 2 Output: 7 Explanation: First Transformation (t = 1): 'a' becomes 'b' 'b' becomes 'c' 'c' be…  ( 26 min )

    How to Create a Lua Wrapper for C++ Functions
    Introduction Integrating C++ functions with Lua can be a powerful way to enhance scripting capabilities in your applications. In this article, we will explore how to create a robust wrapper that allows Lua scripts to call various C++ functions seamlessly. This approach is particularly useful when re-using existing code without the need for an entirely new interface. Why Integrate Lua with C++? Using Lua as a scripting language provides flexibility and ease of use. The Lua C API allows you to register C/C++ functions that can be called directly from Lua scripts. This means that instead of creating new implementations of these functions for Lua, you can use your existing C++ functions, significantly reducing development time.

    US lawmakers call for change in corporate digital asset taxes
    Two US senators are calling on Treasury Secretary Scott Bessent to “exercise [the department’s] authority” and change a provision affecting taxes on corporate holdings of digital assets. In a May 12 letter, Senators Cynthia Lummis and Bernie Moreno suggested Bessent had the authority to change the definition of “adjusted financial statement income” under existing US law in a way that could reduce what digital asset companies pay in taxes. The proposed adjustment was suggested as a way to modify a provision of the Inflation Reduction Act, signed into law in 2022. “Our edge in digital finance is at risk if US companies are taxed more than foreign competitors,” said Lummis in a May 13 X post.

    Coinbase invests in Canadian stablecoin issuer
    Coinbase has partnered with Canadian stablecoin issuer Stablecorp in a bid to expand access to tokenized Canadian dollars, a company executive told Cointelegraph during the Blockchain Futurist Conference in Toronto. According to Coinbase Canada's CEO, Lucas Matheson, the exchange is investing an undisclosed amount in Stablecorp and will help market its fiat-collateralized stablecoin, QCAD. “It’s really important that we have a stablecoin for Canadians,” Matheson told Cointelegraph in an exclusive interview on May 13, adding that stablecoins are especially urgent because the country has “no peer-to-peer [payment] rail” and “wire transfers cost $45 and take 45 minutes of paperwork.” “With stablecoins, 24/7, instant, borderless payments become possible — this is already feasible with existin…

    What are the next steps for the US stablecoin bill?
    Proponents of a bill to regulate stablecoins in the US Congress will likely take up another vote on the legislation in a matter of days without responding to concerns about President Donald Trump’s financial ties to the cryptocurrency industry. The Guiding and Establishing National Innovation for US Stablecoins, or GENIUS Act, failed to get enough votes to pass in the US Senate on May 8 amid calls from some Democratic lawmakers to halt any legislation related to digital assets until Republicans could address Trump’s potential conflicts of interest. Immediately following the vote, some lawmakers from both parties suggested they could reconsider the bill as early as this week, but without agreeing on a bipartisan path forward. After the GENIUS Act failed to proceed in a 48 to 49 vote in the…

    SEC hacker counters prosecutors with 366-day sentencing recommendation
    Defense lawyers have asked a judge to sentence the person responsible for helping post a fake message announcing regulatory approval of Bitcoin exchange-traded funds to roughly a year in prison, countering prosecutors’ request for a two-year sentence. In a May 13 filing in the US District Court for the District of Columbia, Eric Council Jr.’s legal team asked that he be sentenced to no more than one year and one day in prison following his guilty plea. Council was part of a group that took control of the US Securities and Exchange Commission’s (SEC’s) X account in 2024 through a SIM swap attack, posting a message that suggested the regulator had approved spot Bitcoin (BTC) exchange-traded fund listings for the first time. “A sentence of twelve months and one day serves the ends of justice…

    Bitcoin remains unmatched as a global inflation hedge
    Opinion by: Jupiter Zheng, Partner Liquid Fund at HashKey Capital Whenever Bitcoin falls in value, the narrative is always the same: It’s failing as a hedge against inflation. In the eyes of critics, Bitcoin is not the “digital gold” that so many others claim it to be. With gold hitting all-time highs, these critics have grown louder. If Bitcoin is an inflation hedge, they ask, why isn’t it also rallying as investors seek safety? Even in today’s bearish, high-inflation environment, the cardinal truth holds: Bitcoin is an inflation hedge — arguably the most important one for long-term capital preservation the world has seen.  Strength in scarcity Bitcoin has a hard cap of 21 million coins, with full circulation expected by 2140. This built-in scarcity mirrors gold, which has historically se…

Charlie Yechuan Hu, CEO of Bitcoin layer-2 protocol Bitlayer, shared his insights on venture capital (VC) firms in the Bitcoin (BTC) ecosystem. Hu told Cointelegraph that he views many VC firms in the space positively, as they offer support to early ventures that need capital to build infrastructure. “You need developers, you need to open up the whole ecosystem foundation, everything,” Hu said. “You need to pay for the cloud, like AWS or RPCs, all that, servers […] So, we have to have VC on that.“ Hu argued against the usual Bitcoiner ethos that argues against outsider capital, saying,…

    Animoca eyes New York listing, cites Trump’s crypto-friendly stance
    Hong Kong-based Animoca Brands is preparing for a listing in New York, citing US President Donald Trump’s relaxed regulatory stance on digital assets as a window of opportunity to enter the world’s biggest capital market. Animoca executive chair Yat Siu told the Financial Times that an announcement may be made soon, with the company currently evaluating various shareholding structures. Siu said the decision to pursue a US listing would not hinge on market conditions but rather on timing and strategic positioning. Animoca, which was delisted from the Australian Securities Exchange in 2020 over governance concerns and the status of some cryptocurrencies, has since built a robust investment portfolio, including stakes in OpenSea, Kraken and Consensys.

    Caitlyn Jenner memecoin buyers to regroup after judge tosses suit
    The lawyer for a group of Caitlyn Jenner memecoin buyers said they will continue their legal fight against the ex-Olympian after a judge threw out the case for failing to adequately support the securities and fraud claims it brought. Jenner had escaped a class-action lawsuit from buyers of her self-titled memecoin, Caitlyn Jenner (JENNER) after California District Court Judge Stanley Blumenfeld Jr. said in a motion filed on May 9 that it was “sufficient to conclude that all nine causes of action are deficient” and sided with Jenner in dismissing the suit in its entirety for failure to state a claim. He allowed the class group to amend its suit, which must be filed by May 23, but warned it had “to be more focused and judiciously pleaded” than the original. A lawyer for the class group, Fitz…
    Craig Wright sent enemies to legal ‘hell,’ says judge in restraining order

His lawsuits forced people into costly and time-consuming legal defenses, often based on fabricated evidence, the judge added as he handed out a General Civil Restraint Order or injunction against Wright, prohibiting him from filing any more civil claims or applications in the High Court.  The court highlighted how this strategy was part of a pattern of abusi…

A lower-than-expected US Consumer Price Index (CPI) print could boost Bitcoin, but a higher CPI may increase bearish pressure, leading to a price drop below $100,000.

    US prosecutors recommend 2 years for SEC hacker
    The US government has asked a federal judge to impose a two-year sentence for Eric Council Jr., the individual who helped post a fake message announcing the approval of Bitcoin exchange-traded funds through the Securities and Exchange Commission’s (SEC’s) X account. In a May 12 filing in the US District Court for the District of Columbia, prosecutors recommended Judge Amy Berman Jackson sentence Council to two years in prison for his role in posting a message to the social media platform X suggesting that the SEC had approved spot Bitcoin (BTC) exchange-traded funds (ETFs) for the first time in January 2024. The fake announcement, which shook markets in the roughly 24 hours before the regulator actually approved spot Bitcoin ETFs, led to the arrest of Council. “This case deserves a guideli…
    SEC Chair: Blockchain 'holds promise' of new kinds of market activity
    Blockchain technology could enable “a broad swath of novel use cases for securities” and foster “new kinds of market activities that many of the Commission’s legacy rules and regulations do not contemplate today,” Securities and Exchange Commission (SEC) Chairman Paul Atkins said. During his keynote address at the Commission’s May 12 roundtable on tokenization and digital assets, Atkins welcomed “a new day at the SEC,” adding that “policymaking will no longer result from ad hoc enforcement actions. Instead, the Commission will utilize its existing rulemaking, interpretive, and exemptive authorities to set fit-for-purpose standards for market participants.” Source: U.S. Securities and Exchange Commission A key priority will be to “develop a rational regulatory framework for crypto asset mar…

Select altcoins have continued to move higher, indicating increased investor interest.   The SPX and the DXY are playing catch-up to Bitcoin following the US-China trade deal. Bitcoin (BTC) has started the new week on a cautious note, falling below $103,000, but the S&P 500 Index (SPX) and the US Dollar Index (DXY) have risen sharply following the announcement of the US-China trade agreement. One of the reasons could be that other assets are trying to play catch up with Bitcoin, and the sharp rally in the US dollar may be acting as headwinds for Bitcoin in the near term.

    Bitcoin price sells off after Trump’s US-China tariff deal — Here is why
    Key takeaways: Bitcoin lags as investors shift toward stocks after the US and China strike a deal that could end the current trade war. Macroeconomic conditions are swinging away from gold investing and back to stocks.  Bitcoin (BTC) reached its highest price in over three months at $105,720 on May 12, but was unable to maintain its bullish momentum. Interestingly, the drop to $102,000 came after a temporary easing in the US-China tariff conflict. This has left traders puzzled as to why Bitcoin reacted negatively to what seemed like positive developments. The 90-day truce reduced import tariffs, and US Treasury Secretary Scott Bessent noted that the agreement could be extended, provided there is a genuine effort and constructive dialogue. According to Yahoo Finance, the topics under dis…
    BlackRock flags quantum computing as risk for Bitcoin ETFs
    Emerging technologies, including quantum computing, could potentially render the cryptography securing Bitcoin and other blockchain networks ineffective, asset manager BlackRock said in a regulatory filing.  On May 9, BlackRock updated the registration statement for its iShares Bitcoin ETF (IBIT). The revised version addressed potential risks to the integrity of the Bitcoin network posed by quantum computing, the filing shows. “[I]f quantum computing technology is able to advance […] it could potentially undermine the viability of many of the cryptographic algorithms used across the world’s information technology infrastructure, including the cryptographic algorithms used for digital assets like bitcoin,” BlackRock said.

    Bitcoin short-term ‘technical sell-off’ under $100K possible ahead of May 13 CPI print
    Key takeaways: Possible de-risking ahead of the May 13 CPI print could be playing a role in today’s BTC price correction.

Bitcoin (BTC) price briefly stumbled on May 12, falling to $102,388 after hitting an intraday high at $105,819 during the US trading session.

    Will Bitcoin hodlers be the reason more countries adopt wealth taxes?
    Opinion by: Robin Singh, CEO of Koinly Is there a catch for Bitcoin hodlers, with the asset’s price up over 600,000% since the beginning of 2013?  Perhaps — if governments keep waking up to Bitcoin’s value, the whole “you only pay tax when you sell” mantra could soon be a thing of the past. What if a wealth tax is the answer for revenue-hungry tax agencies with no time to lose? It’s a yearly tax on a person’s total net worth — cash, investments, property and other assets — minus any debts, applied whether or not those assets are sold or generating income. The idea is to boost public revenue and curb inequality, mainly by taxing the ultra-rich. A wealth tax takes a clip off what you own, not what you earn. Countries such as Belgium, Norway and Switzerland have had wealth taxes baked into th…

    Bitcoin, altcoins poised to rally on US-China tariff agreement
    A 90-day tariff agreement between the US and China may set the stage for a broader recovery of stock and cryptocurrency markets, as investors look ahead to a potential tax relief package.

Speaking at a press conference in Geneva, US Treasury Secretary Scott Bessent said both governments are aligned on avoiding further economic decoupling. “The consensus from both delegations is neither side wants to be decoupled,” Bessent said. “What has occurred with these very high tariffs was an equivalent of an embargo, and neither side wants that. We do want trade. We want more balance in trade.” Joint statement on US-…

    What is RISC-V, and why does Vitalik Buterin want it for Ethereum smart contracts?
    What is RISC-V? RISC-V, pronounced “risk five,” is a modern open-source instruction set architecture (ISA) based on reduced instruction set computer (RISC) principles. In simple terms, it’s like a blueprint that defines a set of instructions that a processor can execute. RISC-V is designed to be highly modular, efficient and flexible. Originally developed by the University of California in 2010, the open-source framework gives developers the flexibility to tailor its functionality and use cases, plus offers cost savings compared to proprietary ISAs like ARM or x86. This offers a wide range of uses, from supercomputers to smartphones and now blockchains like Ethereum. On April 20, 2025, Ethereum co-founder Vitalik Buterin unveiled a “radical” new sc…

    Can you stake Bitcoin (BTC)? Here’s what you need to know
    Key takeaways Though Bitcoin doesn’t support native staking, holders can earn yield through centralized lending platforms, Wrapped Bitcoin (WBTC) on Ethereum, and Bitcoin-related networks like Babylon and Stacks. WBTC allows BTC holders to participate in lending, liquidity pools and yield farming on Ethereum-based DeFi platforms like Aave and Curve but introduces bridge and smart contract risks. Protocols like Babylon and Stacks use mechanisms like native time-locked scripts or stacking to offer rewards without removing BTC from the Bitcoin blockchain. Custodial, smart contract and regulatory risks persist. Bitcoin’s community also remains divided on whether Bitcoin yield generation features align with its decentralized and trust-minimized ethos.

    Trump’s US-China trade deal could shed light on Bitcoin’s use case
    Bitcoin’s potential price reaction to a trade deal between the United States and China could give insights into whether Bitcoin is being used as a safe-haven asset in the current market. Bitcoin (BTC) outperformed stocks and held up “incredibly strong” during a sharp sell-off on stock markets in April, following Donald Trump’s announcement of tariffs on “Liberation Day,” observed crypto trader “Daan Crypto” on May 11.

On May 9, the Northern Mariana Islands Senate voted 7-1 to override Governor Arnold Palacios' April 11 veto of the bill, which would allow the Tinian local government to issue licenses to internet casinos and includes a provision for the Tinian treasurer to issue, manage and redeem a “Tinian Stable Token.”  The bill will now head to the 20-member Northern Mariana Islands House, which will need a two-thirds majority vote to override the veto and pass the bill into law.

    Why Your Cloud Strategy Keeps Failing (And How I Fixed It)
    Let’s be honest: most cloud “strategies” I come across aren’t really strategies — they’re glorified lift-and-shifts. On paper, migrating to the cloud promises flexibility, scalability, and cost savings. But in reality? Many organizations just copy their on-prem setup into AWS, Azure, or GCP — and call it done. As someone who’s spent years helping companies build scalable, secure, and cloud-native infrastructure across multi-cloud environments, I’ve seen this mistake over and over. But one project in particular made this painfully clear. The Lift-and-Shift That Didn’t Shift Anything But what I found was this: configured almost exactly like their legacy setup. 2.They managed access using manually configured Security Groups and Network ACLs — trying to mimic their old firewall rules. 3.Scalin…  ( 4 min )

    🧩 Rust vs Solidity: Why Solana Uses Rust — Explained Simply
    Solana and Ethereum are two of the most popular blockchains in the world. But if you look under the hood, you’ll notice they speak different “languages.” Ethereum uses Solidity, while Solana uses Rust. So… what’s the difference? And why does it matter? Let’s break it down in plain English. Think of Solidity and Rust like languages people use to build apps — just like websites are built with HTML or JavaScript. Solidity was created specifically for blockchains — especially Ethereum. It’s simple, beginner-friendly, and looks a bit like JavaScript. Rust is more like the serious, high-performance cousin. It’s used to build powerful software like games, browsers, and now — Solana. One of the biggest problems in crypto? Bugs and hacks. Solidity, while easier to use, has been behind many major De…  ( 4 min )
    Laravel Observer: Its Superpowers in Event Structuring
    What is a Laravel Observer? Observers in Laravel are used to listen for specific events on Eloquent models, such as creating, updating, and deleting records. The main advantage of using them is the ability to delegate the data handling logic to a dedicated class, keeping controllers and models leaner. Imagine you need to perform an action every time a user is created. Instead of writing that logic directly in the controller or the model, you can use an Observer to ensure that the logic is isolated and easier to test. Creating an Observer in Laravel is very simple. Let's take a look at a basic example of an Observer for a User model: php artisan make:observer UserObserver --model=User Open the App\Providers\EventServiceProvider file and register the observer: public function boot() { …  ( 4 min )
    Should we start a podcast interviewing our ex-music-school-classmates?
    I'm thinking about starting a podcast with @blumen where we interview a bunch of somewhat successful / living-their-livelihoods-off-of-music people we went to music school with, and see where they are today. Basically Celebrity Catch Up: Life After I Did That Thing but without the Celebrity and without The Thing. 😬 Typing it out now makes it seem like a pretty bad idea, but I think it could be good information gathering for anyone considering music school or working in music. Plus, it would be amusing for our little cohort of music school grads and a fun way for us to reconnect with some folks. According to music-colleges.com (lol), SUNY Fredonia's music program ranks at #276 (out of 1451 schools they evaluated, so technically in the 20%!!). I imagine a podcast like this about Julliard grads would be much more successful, but those people probably wouldn't have good advice or relatable stories for real, non-prodigious but competent musicians. So far our initial brainstorm has us landing around: 30-45 min max Asking people about: What they studied How much schooling they ended up getting Their most memorable Fredonia experience What they do now Career highlights Career lows How much money they currently make (from music) What their advice would be for anyone pursuing their current career, or the program they studied in school Thoughts?  ( 3 min )
    The Philosophy of Film Editing
    The Editor as a Storyteller: Crafting Meaning Through Cuts Film editing is far more than a technical exercise in arranging images; it is a profound act of storytelling. The editor shapes narrative, rhythm, emotion, and even truth by deciding what the audience sees—and when they see it. This power to construct meaning through selection and sequencing makes the editor an essential co-author of a film’s emotional and intellectual impact. At its core, editing transforms raw footage into a coherent and resonant experience. Through choices in duration, order, and juxtaposition, editors influence how characters are perceived, how themes develop, and how a story unfolds. The emotional arc of a scene—whether tranquil or intense—often hinges more on the cut than the shot itself. Editing allows a f…  ( 6 min )

    How to Resolve Address Bar Update Issues in Windows File Explorer

In this article, we'll explore the root cause of this issue, an effective workaround, and discuss potential solutions.

    JavaScript Closure Simplified
    Have you ever wondered how JavaScript functions can "remember" things even after they've finished running? That’s the magic of closures, and today we’ll break it down with a simple use case: building a custom counter function. We’ll touch on key concepts like function factories and state persistence to bring this idea home. Closures: For example, in our counter, a variable count is defined inside makeCounter(). The inner function (the actual counter) uses this variable. Thanks to the closure, the count is not lost when makeCounter() finishes, the counter function still remembers it. Function Factory: One Function, Many Counters Think of makeCounter() as a factory. Every time you call it, it gives you a brand new counter, like a fresh instance with its own private count. Each counter is completely independent. State That Sticks(State Persistence) The beauty of closures is state persistence. Since count is part of the closed-over scope, it keeps its value between function calls. That’s what allows the returned function to keep incrementing the same number, step by step. The key takeaway: even though makeCounter() is finished, the returned function still has access to everything defined inside it. That’s the closure in action, enabling encapsulation, memory, and a clean way to manage state without global variables. Closures aren’t just cool, they’re powerful. Once you understand them, you’ll start seeing them everywhere in JavaScript. And best of all, they make patterns like private counters, once complex, totally natural.  ( 3 min )
    A Simple Framework for Designing User Interfaces (for Solo Devs & Small Teams)
    If you're building a product as a solo dev or part of a small team, you've probably struggled with design. You open Figma. You pick a font. Then a color palette. Then you browse some Dribbble shots. Then you go down a dark hole of animations, blur effects, neumorphism... and suddenly you've spent three hours tweaking gradients but your product still doesn't feel right. Here's the problem: you're thinking about design backwards. Design isn't about how your app looks. It's about what it lets people do and how easily they can do it. That's why I follow a dead simple rule: Design functionality first. Make it beautiful later. Design isn't about how something looks it's about what it lets people do. When you focus on visual details too early, you're decorating an idea that hasn't even proven its…  ( 5 min )
    Hello! 😊
    Hi DEV community! My name is Jo. I am a Digital Designer and Learning Technologist at the University of Leeds with a specialism in UX design and web accessibility. My coding journey started over lockdown when I completed a coding bootcamp with The Coders Guild, learning HTML, CSS, basic JavaScript, bootstrap, and Git. I will be honest, I don't need to use it every day for my career so I did forget some of what I've learnt since then but I have started to pick it back up again! My background is in graphic design so I hope to utilise my knowledge in this field to create more visually stunning web experiences. Currently with the support of my colleague, I help create bespoke web development projects that supplement the learning within our online course portfolio. For me personally, these projects are very basic (and partly supported by ChatGPT) because I am still learning... but I hope to change that! My goal is get to the point where I am much better and more confident in my skills at front-end web development and require less hand-holding. I also want to create diverse interactive experiences to hopefully foster genuine curiosity for the subject matter with our students and engage them with the learning material. Managers are more interested in boosting the reputation of the university, but the most important thing for me is to promote academia and make learning fun! Most of my posts will be misc stuff I've learnt and will probably be written with bad or inefficient code rather than being effective tutorials so please read with caution! Thank you for coming on this coding journey with me! If you'd like to connect, my LinkedIn profile is linked before (I no longer use any other social media platform anymore for my professional presence). I am in the process of coding my own website so be sure to keep a look out for this in due time! LinkedIn: https://www.linkedin.com/in/jolaw233/  ( 3 min )

    How to Log Python and Bash Output Chronologically in a File
    When working with Python and Bash scripts, logging output can become cumbersome, especially when you want to preserve the chronological order of the messages. The challenge you’re facing is that output from your Bash script is appearing in the log file before the output from your Python script due to buffering issues. This article will guide you through the best practices for ensuring that all outputs are recorded in the correct order, using file descriptors effectively. Understanding Output Buffering When Python writes output to a log file, it may use buffering, meaning it collects a certain amount of data before writing to the file.

    Implementing a Radically Simple Alternative to Graylog
    Back in 2022, my team and I were working on a service which was printing a fairly sizeable amount of logs from a distributed cluster of 20+ hosts: about 2-3 million log messages per hour in total. We were using Graylog, and querying those logs for an hour was taking no more than 1-3 seconds, so it was pretty quick. Infra people hated Graylog though, since it required some annoying maintenance from them, and so at some point the decision was made to switch to Splunk instead. And when Splunk was finally rolled out, I had to find out that it was incredibly, ridiculously slow. Honestly, looking at it, I don't quite understand how they are even selling it. If you've used Splunk, you might know that it has two modes: “Smart” and “Fast”. In “Smart” mode, the same query for an hour of logs was tak…  ( 4 min )
    I've just released git-gpt-commit v0.9.0! 🎉
    I've just released git-gpt-commit v0.9.0 — a Git extension that uses OpenAI's GPT models to automatically generate commit messages via the git gpt commit command. The default model has been upgraded to OpenAI’s GPT-4o. blazing-fast response speed (about twice as fast as GPT-4.1), allowing it to generate commit messages in an instant. very cost-efficient, at half the price of GPT-4-turbo. Previously, only English was supported. Now, with: git gpt lang You can choose from 12 languages for your commit messages: Previously, there was no option to add prefixes to your commits. Now, with: git gpt prefix You can toggle the inclusion of commit prefixes like feat:, fix:, or refactor:. Previously, you had to write your API key in a .env file in your project directory. Now, with: git gpt open-api-key You can now safely add and manage your OpenAI API key directly from the CLI. .env method is still supported as well. git gpt config You can now view all your current settings at once. Once installed, start by registering your OpenAI API key using the command above. Then, just stage your changes with git add, and run: git gpt commit The tool will analyze the staged changes, send them to the GPT model, and generate a context-aware commit message. You’ll need an OpenAI API key. npm install -g @laststance/git-gpt-commit While IDEs like VSCode and Cursor offer AI-assisted commit message generation, I couldn’t find a CLI tool that does the same — and that’s where I spend most of my time working with Git. Most of the features I personally wanted are now implemented, so I’m pretty happy with this release. Links: GitHub|npm  ( 4 min )

    Finding the Row Containing a Target in a Sorted Matrix in Python
    In this problem, you're given a matrix of integers where each row and each column is sorted in ascending order. The goal is to find the index of the row that contains a specific target value. If the target value is not found in the matrix, return None. This is a common matrix problem that can be solved efficiently by taking advantage of the sorted structure. Instead of checking each cell (which would take O(n × m) time), you can reduce the complexity to O(n + m), where n is the number of rows and m is the number of columns. We make use of the matrix's properties—namely that values increase as we move right and down, and decrease as we move left and up. Start from the top-right corner of the matrix. Use a loop to traverse the matrix: If the current value equals the target, return the current row index. If the current value is greater than the target, move left. If the current value is less than the target, move down. If the loop completes without finding the target, return None. def find_row_with_target(matrix, target): if not matrix or not matrix[0]: return None # Matrix is empty n = len(matrix) # Number of rows m = len(matrix[0]) # Number of columns # Start at the top-right corner row, col = 0, m - 1 while row = 0: if matrix[row][col] == target: return row # Target found elif matrix[row][col] > target: col -= 1 # Move left else: row += 1 # Move down return None # Target not found matrix = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12] ] print(find_row_with_target(matrix, 7)) # Output: 1 print(find_row_with_target(matrix, 13)) # Output: None This solution demonstrates how understanding data structure properties can lead to more efficient algorithms. Instead of brute-force search, a directional approach through the matrix takes full advantage of the sorted nature, resulting in a linear time complexity relative to the dimensions of the matrix.  ( 4 min )

    How to use EXPLAIN to fix slow queries in MySQL
    Slow queries can quietly erode performance, which frustrates users and strains your system. Fortunately, MySQL offers EXPLAIN, a diagnostic tool that reveals how your queries execute. Think of it as a window into your database engine’s decision-making process. With EXPLAIN, you can figure out exactly why a query is underperforming. Maybe it’s looking at too many rows, ignoring indexes, or struggling with joins. This understanding is key for developers and database administrators who are aiming to optimize performance. To use EXPLAIN, simply place it before your query. It works with SELECT, INSERT, UPDATE, or DELETE statements. For instance: EXPLAIN SELECT name, email FROM customers WHERE age > 30; This will return the query execution plan in table format. +----+-------------+-----------+…  ( 8 min )

    Modern CSS Spritesheets with Native HTML Elements
    The common approach to using sprite sheets involves applying CSS classes with pre-calculated coordinates to control the positioning within the sheet. This typically relies on background-image, which does not natively support features like alt text or lazy loading that come built-in with elements. Additionally, using can improve accessibility and semantics depending on how the image is used. This approach builds upon an article on css-tricks, and expands it by introducing scaling of the individual sprites. Skip to Codepen Demo object-fit: none and object-position: x y allow us to select specific areas of an image which is the basis of this idea.

    Ditching Postman: Why and How I Transitioned to Bruno
    As a developer who regularly works with APIs, Postman has been the go-to choice for testing, documenting, and sharing across teams. However, over time, I began to feel the bloat. Postman became increasingly heavy, slow to start, and frustrating to use in version-controlled environments. That's when I discovered Bruno: a lightweight, open-source API client aiming to take on Postman's heavyweight legacy. In this article, I'll walk you through why I made the switch from Postman to Bruno, what the transition looked like, and how my workflow has improved. Needing no introductions, Postman is undoubtedly a powerful tool. But with power often comes weight: Resource Heavy: Postman's Electron-based architecture makes it noticeably slow and memory-hungry.

    In the Programming World, There Are SIMPs Too
    Let’s talk about something nobody puts on the shiny LinkedIn posts: there are SIMPs in tech too. And no, I’m not talking about romantic simping. I’m talking about people who worship tools, companies, frameworks, or tech celebrities like they’re gods — and lose all critical thinking along the way. Yeah. That kind of SIMPing. The Cult of Tools You’ve probably seen it. Some new framework drops. Some company open-sources a tool. Some CEO posts a half-baked thread on X about “changing the world with AI” and suddenly... there’s a flock of devs blindly defending it like their paycheck depends on it (spoiler: it doesn’t). “X framework is the future! Everything else is trash!” “If you’re not using Y, you’re falling behind!” “Z founder said it, so it must be true!” Bro. Chill. Tools are just tool…  ( 4 min )

    How Manual QA Can Implement Left-Shift Testing in Frontend
    Introduction In traditional software development, testing often occurs late in the cycle, leading to bottlenecks and delayed releases. Left-shift testing is a proactive approach where testing activities are introduced earlier in the development lifecycle. While automation is often associated with left-shift testing, manual QA testers can also play a crucial role in implementing this strategy—especially in frontend development. This article explores how manual QA testers can adopt left-shift testing principles to improve frontend quality, reduce defects, and accelerate delivery. Left-shift testing means shifting testing activities left (earlier) in the software development lifecycle (SDLC). Instead of waiting for a fully developed feature, testers engage early in requirements, design,…  ( 5 min )

    How to Create Unique ASCII Art Boxes with Background Colors
    Introduction Creating visually appealing ASCII art boxes with distinct background colors can pose a unique challenge for web developers. Traditional methods often involve using multiple div elements to simulate intricate boxes, which can be cumbersome and inefficient. In this article, we'll explore a more effective way to design ASCII art boxes that not only enhances visual appeal but also offers you the flexibility to create varied shapes and sizes effortlessly. Why Traditional Methods Are Limiting Many developers resort to using two overlapping div tags to create the illusion of a colored background within an ASCII box. While this method can work, it often complicates the implementation. Adjusting the size of each box requires recalibrating both divs, which is not only tedious but can le…  ( 5 min )

    MySQL vs MongoDB for SaaS: Which Database Should You Choose in 2025
    For a SaaS (Software as a Service) product, choosing between MySQL and MongoDB depends heavily on the type of data, scalability needs, and how the app works. Use Case Recommendation Traditional SaaS (multi-tenant, structured data, relational) ✅ MySQL Flexible, unstructured, dynamic data (e.g., user-generated content, document-heavy) ✅ MongoDB Feature MySQL (Relational) MongoDB (NoSQL Document) Data Structure Tables, Rows, Foreign Keys (SQL) JSON-like Documents (BSON) Schema Fixed schema (strong structure) Schema-less (flexible) Joins & Relationships Native support Complex joins are harder Transactions Strong ACID support ACID (limited or requires special setup) Scalability Vertical + Read replicas Easily horizontally scalable Performance Great for complex queries, joins Fast for large, flexible datasets Multi-Tenancy Support Very strong (tenant per row, schema, DB) Requires thoughtful design MySQL: SaaS with complex relational data (users, roles, payments, subscriptions). Requires data integrity and transactions (e.g., financial systems). Example: B2B CRM, ERP, Invoicing software. Strong multi-tenant support using shared schema with tenant_id. MongoDB: SaaS with highly dynamic or nested data, like CMS or analytics dashboards. You don’t rely heavily on relationships or joins. You need to store flexible documents per user. Faster iterations and schema evolution. SaaS Type Best DB Project Management Tool (tasks, users, teams) ✅ MySQL CMS/Blog Platform ✅ MongoDB Analytics or IoT Dashboard ✅ MongoDB Accounting / Billing SaaS ✅ MySQL Chat/Messaging SaaS ✅ MongoDB (with Redis/Cache) Some large SaaS companies use both: MySQL for core user/accounts/transactions. MongoDB or ElasticSearch for logs, analytics, unstructured content. If you are: Building a structured SaaS with users, payments, plans, etc. → go with MySQL Building a dynamic content-based platform or analytics service → go with MongoDB  ( 3 min )
    When Your Login Page Becomes the Frontline: Lessons from a Real-World enumeration attack
    As an IAM SaaS company, our work often remains in the shadows—until something goes wrong. Today, I want to shed light on how we handle security at the very first layer all IAM systems have: the login page. Specifically, I’ll walk you through an incident we managed at Cloud-IAM, where we provide a managed Keycloak solution, and share some insights on securing authentication systems against evolving enumeration attack threats. Many of our clients are tech enthusiasts and small companies that want to avoid the complexity of configuring and maintaining Keycloak. Our larger clients, on the other hand, demand resilience. However, resilience is often measured in terms of Monthly Active Users (MAUs), without fully considering the exposure of their service. For example, take two hypothetical compa…  ( 6 min )
    How to Fix JWT Signature Validation Errors in C#
    When working with JWT authentication in C#, you might encounter a common issue: the token signature validation fails due to a missing 'kid' (Key ID) in the header. This issue often surfaces when using the HS256 algorithm without a kid component, particularly when your token is validated against a set of keys that do not match. Understanding JWT Tokens and Signature Validation JWT (JSON Web Token) is a widely used token format for secure communication between parties. A JWT typically consists of three parts: header, payload, and signature. The header contains information about how the token is signed, including its algorithm and, optionally, a 'kid' if multiple signing keys are involved. In situations where the 'kid' is missing, the application may not be able to match the signing key prope…  ( 4 min )
    Beyond the Stars: The Euclid Space Observatory and its Quest to Map the Universe

    Why Managed Side Effects Are a Deliberate Design Decision in Elm
    Elm is renowned for its commitment to reliability and predictability in web applications. One of the key design decisions behind Elm’s success is its strict enforcement of managed side effects. Unlike many other languages where developers can introduce side effects at will, Elm mandates that all interactions with the outside world be handled only through its controlled mechanisms. This deliberate choice helps maintain purity, consistency, and overall code health. In this post, we’ll explore: What side effects are and why arbitrary side effects can be problematic. The advantages of Elm’s enforced, managed approach. How Elm implements this design with Commands (Cmd) and Subscriptions (Sub). Real-world scenarios that benefit from this disciplined strategy.

    The Rise and Fall of Comet ATLAS
    “An icy visitor flames out in dramatic fashion”– Sean Walker A comet is a small icy object that orbits the Sun. It’s made of dust, rock, and frozen gases (like water ice, carbon dioxide, and more). I’m sure that everyone’s familiar with this definition of a comet, but today we’re not talking about comets in general but a specific one — ATLAS! Comet ATLAS or C/2024 G3 was named after ATLAS- Asteroid Terrestrial-impact Last Alert System, which was the first to discover it. Comet ATLAS was a 19th-magnitude object. To explain, the magnitude of an object measures its brightness. The brighter the object the lower the number. The comet is also described as having a diffuse coma and a short tail. A coma is a cloud of gas and dust that forms around the nucleus of a comet upon receiving heat from th…  ( 4 min )
    File Read & Write
    In Java, file reading and writing can be done efficiently using buffered streams, readers, and writers. Here's a short explanation with examples: 1. Buffered File Reading (Using BufferedReader) Buffers data for efficient reading (instead of byte-by-byte). import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; public class ReadFile { public static void main(String[] args) { try (BufferedReader reader = new BufferedReader(new FileReader("file.txt"))) { String line; while ((line = reader.readLine()) != null) { // Reads line-by-line System.out.println(line); } } catch (IOException e) { e.printStackTrace(); } } } 2. Buffered File Writing (Using BufferedWriter) Buffers data for efficient writing. import java.io.BufferedWriter; import java.io.FileWriter; import java.io.IOException; public class WriteFile { public static void main(String[] args) { try (BufferedWriter writer = new BufferedWriter(new FileWriter("output.txt"))) { writer.write("Hello, Java!"); writer.newLine(); // Adds a newline } catch (IOException e) { e.printStackTrace(); } } } 3. Key Classes Class Purpose FileReader / FileWriter Reads/Writes characters (text files). BufferedReader / BufferedWriter Wraps readers/writers for buffered I/O. FileInputStream / FileOutputStream Reads/Writes bytes (binary files). Scanner Alternative for reading text (e.g., new Scanner(new File("file.txt"))). 4. Try-with-Resources Automatically closes files (no need for finally blocks). Used in the examples above (try (BufferedReader ...)). When to Use? Use BufferedReader/BufferedWriter for text files. Use FileInputStream/FileOutputStream for binary files (images, etc.). Use Scanner for parsing structured text. Let me know if you'd like a deeper explanation! 🚀  ( 3 min )

    The Art of Deep Comparison in JavaScript (No Loops Required!)
    ✅ Understanding the Goal You're being asked to implement a function called deepEqual(valueA, valueB) that checks if two values (which can be primitives, objects, or arrays) are deeply equal. The keyword here is deep, this means we can’t just check equality on the surface (like ===), especially for things like objects and arrays. We need to go into nested levels and check if all elements or properties match recursively. 🧠 Think Like This, Before you jump into code, ask yourself questions like: -> What types of values can valueA and valueB be? -> How do I handle primitive types vs arrays vs objects? -> What does it mean for arrays or objects to be “equal”? -> Should I use recursion? 🤔Design Your Thinking Strategy: Base case: If a === b, return true. Type check: If types differ, return false. If both are arrays: Check length. Recursively compare each element. If both are objects (but not arrays): Compare keys. Recursively compare each corresponding value. Otherwise: return false. 🔁 Why Recursion? Why Loops Alone Aren’t Enough? A simple for loop works great when you're comparing flat structures, like two arrays of numbers. But when the data can go many levels deep , arrays inside objects inside arrays, etc. you’d need: a loop inside a loop inside a loop... 😵 or a smarter approach that can handle any depth That’s Where Recursion Shines. Recursion is perfect for tree-like or nested structures, because you can say: “If the current level is an array or object, go deeper and run the same logic again.” So your function ends up being clean and adaptable to any depth. ⚡️Implementation of the deepEqual function using recursion: With a clear understanding of recursion and careful handling of data types, you now have a robust deepEqual function that can accurately compare even the most nested structures, a must-have tool in any JavaScript developer's toolkit.  ( 3 min )
    Why Netflix Doesn’t Trust Auto-Increment IDs: The Untold Power of UUIDs in a Distributed World
    At first glance, an ID might seem like the most boring part of your application. It's just a unique identifier, right? But if you're building systems that scale - across regions, across teams, across microservices - your ID generation strategy can be the silent hero or the hidden landmine. And that’s exactly why companies like Netflix, Twitter, Stripe, and Shopify have ditched traditional auto-incrementing IDs in favor of UUIDs and Snowflake-like systems. Let’s explore why UUIDs are not just random gibberish, but a critical architectural decision in high-scale systems - and what lessons we can steal from the giants. Auto-incrementing integers are deceptively simple and convenient. They work great when: You have a single database. You can guarantee a single source of truth. You're not worri…  ( 5 min )
    What Are the Differences Between Variable Definition, Initialization, and Assignment in C++?
    When reading discussions about C++ variable definitions and their associated rules, it’s essential to understand the distinctions between variable definition, initialization, and assignment. Each concept plays a crucial role in how variables behave within C++ code, and knowing these differences can significantly enhance your programming efficiency. Let's delve deeper into variables in C++ and clarify these terms with examples. Understanding Variable Definition In C++, variable definition is the process of declaring a variable to let the compiler know the variable’s type and its name. For instance: int x; // Variable definition Here, int x; tells the compiler to reserve space in memory for an integer variable named x. However, at this point, x does not hold any value; it’s simply defined. …  ( 5 min )
    Google’s “Desktop View” Might Just Kill Samsung DeX

You'll learn when to use built-in methods versus external libraries, how to properly handle localization and time zones, and how to avoid common date-related pitfalls in your projects. Before formatting a date for display, you need to understand the format in which you receive it. Here are the three most common formats, each of which displays the same date and time: ISO 8601 strings (standardized and directly consumable by new Date()) — "2025-02-18T14:30:00.000Z" Unix timestamps (numeric representati…  ( 11 min )
    What is Machine Learning? A Beginner’s Journey Through the World of Smart Algorithms
    Imagine you're trying to teach a child how to recognize fruits. You show them dozens of apples, bananas, and oranges, telling them the name of each fruit. Over time, the child learns to distinguish between them, even when they see new fruits for the first time. This, in a way, is what Machine Learning (ML) is all about—teaching machines to learn from data and make decisions or predictions without being explicitly programmed. 🧠 So, What Is Machine Learning? At its core, Machine Learning is the art and science of solving problems by learning from data. We start with a problem, gather data related to it, and then use algorithms to build a statistical model that can make sense of new, unseen data. But ML isn’t one-size-fits-all. There are several ways to teach a machine, depending on what k…  ( 4 min )

    Can You Use Else If Without Else in JavaScript?
    When you're learning JavaScript, you might find yourself questioning the syntax and structure of conditional statements, particularly if you can utilize 'else if' without including an 'else'. The answer is yes! Let's delve deeper into this topic and clarify how 'else if' can be used independently of 'else', as well as explore some best practices in conditional statements. Understanding If Statements in JavaScript In JavaScript, conditional statements form the backbone of controlling the flow of your code. The primary syntax for an if statement is as follows: if (condition) { // code to execute if condition is true } else { // code to execute if condition is false } However, as you mentioned, the use of 'else if' allows for multiple conditions to be checked sequentially. Here’s the…  ( 5 min )

Remote Work Expansion: Employees now access corporate resources from multiple devices and locations, dissolving traditional boundaries. Cloud Adoption: With workloads moving to the cloud, network-based access control is ineffective. Internal Threats: Trusting internal users witho…  ( 4 min )
    Analyzing the Backward Insertion Sort: An Insightful Tool by Fernando Pelliccioni
    In the vast world of computer science, while the foundations and principles of algorithms remain consistent, the ways we approach, implement, and analyze them continue to evolve. Today, we’ll delve into a distinct implementation of the insertion sort algorithm and an innovative tool that simplifies its analysis, both brought to the fore by Fernando Pelliccioni. The provided algorithm, while rooted in the classic insertion sort paradigm, offers a twist — working its magic backward: `function insertion_sort_backward(f, l, r) { } function linear_insert_backward(c, l, r) { var s = sequence(array_descending(), "s", lt); print(s); Understanding an algorithm is one thing; seeing it in action is another. Fernando Pelliccioni introduces an insightful GUI tool for this very purpose: componentsprogramming.com/algorithms. This interactive platform not only animates the algorithm’s execution but also serves insights into memory sequences, variables, stack calls, and various operation statistics. A glimpse into the potential data output: n: 10 (Note: The above metrics are illustrative and may not reflect the actual values for specific runs.) While the foundational algorithms might be familiar territory, it’s the nuanced implementations and tools for deeper understanding that elevate our coding journeys. Fernando Pelliccioni’s distinct implementation of the insertion sort and the accompanying analysis tool stand as testaments to innovation in the world of algorithms. Whether you’re a programming veteran or a newcomer, the landscape of algorithms always promises fresh terrains to explore.  ( 4 min )
    What’s the Difference Between Friend and Public Functions in C++?

    O cérebro odeia pensar: o poder da interface óbvia
    Dia 2 - Neurointerfaces — Como nosso cérebro enxerga o Frontend “Don't make me think.” — Steve Krug Essa frase virou um clássico do design de interfaces. E ela tem base neurocientífica: nosso cérebro evita ao máximo o esforço cognitivo desnecessário. Segundo a Teoria do Processamento Dual (Kahneman, 2011), o cérebro humano opera com dois sistemas: Sistema 1: rápido, automático, intuitivo. Sistema 2: lento, deliberado, requer esforço. Sempre que possível, o cérebro usa o Sistema 1 — e só ativa o 2 se for realmente necessário. Isso significa que interfaces que exigem leitura, análise ou adivinhação ativam o sistema mais lento — e geram frustração. Ícones sem legenda (usuário precisa adivinhar) Menus escondidos (hambúrguer, submenus profundos) Mudanças de padrão (ex: botão de "enviar" que parece um ícone) Elementos previsíveis e familiares Legendas claras Hierarquia visual forte Espaço em branco bem utilizado Estudos de eye-tracking (rastreio ocular) mostram que usuários criam um padrão de leitura em F na tela. Isso significa que eles escaneiam de cima para baixo e da esquerda para a direita — e ignoram o resto. Kahneman, D. (2011). Thinking, Fast and Slow. Krug, S. (2014). Don't Make Me Think, Revisited: A Common Sense Approach to Web Usability. Nielsen Norman Group (2006). F-Shaped Pattern For Reading Web Content. Essas obras explicam por que o design intuitivo funciona melhor: ele não força o cérebro a sair do “modo automático”. Reduza a necessidade de pensar. Use padrões comuns da web. Priorize clareza sobre criatividade. Não reinvente botões sem motivo. Dê pistas visuais. Ícones com texto, hierarquia, espaçamento. Teste com usuários reais. Se alguém hesita antes de clicar, sua interface não está clara o suficiente. Criar uma interface clara é um ato de empatia: você está poupando energia mental do seu usuário. Se ele entender o que fazer sem precisar pensar, você venceu. Qual interface você achou mais confusa recentemente? Comenta aqui e vamos analisar no próximo post da série! 👇  ( 4 min )

    AI-integrated design systems and component libraries
    What if your design system didn't need to ship components in a component library? From an engineering standpoint, most of a design system's maintenance overhead is creating and shipping components for a specific framework coupled to a styling system of some kind. I've been asking the same thing on Medium. And then built a POC to see if it would work and made it available in Github. If using AI agents, component libraries break free of framework and style constraints by generating components at build time from prompts and generator functions. They're still driven by design through tokens and themes, but without prebuilt components. It gets even better when using RAG for distribution and documentation, eliminating tools like Storybook in favor of on-demand generation by AI agents using the system itself, not a collection of stories or API documentation.  ( 3 min )

    The Pros and Cons of Manual vs Automated Accessibility Testing
    Making digital platforms accessible is no longer just a matter of good practice; it’s often a legal requirement. But more than that, it’s an ethical obligation to ensure everyone, including those with disabilities, can use websites, applications, and services without barriers. Accessibility testing helps identify and fix elements that might hinder users relying on assistive technologies.

    Git Native API Client (free, no login)
    Hey all, We recently started working on an API Client - Voiden - and wanted to share it here to get your thoughts and feedback. Over the past few years, we found ourselves managing way too many tools just to work with APIs: one for api specs, another for docs, a third for tests, etc etc. Eventually it starts to feel more like a performance than actual work. So we built Voiden: A git-native, extensible, and lightweight client that brings everything—specs, docs, tests, mocks—into one place. No bloat, no lock-in, no "platform overhead." Just structured API workflows that don’t fight your tools or your team. A few things we care about: -Reusability and composability : APIs as building blocks, not silos. -Structure over scatter : everything lives together in one workspace. -No sign-in required : you can use it without creating an account. Free and open — we are building this with the community in mind. Just to be clear: The goal is NOT to replace OpenAPI, but to provide a layer around existing specs that feels coherent, hackable, and friendly to real-world dev workflows. You can check it out here: https://voiden.md/ And if you have feedback, suggestions, or just want to follow along: https://github.com/VoidenHQ/feedback We are still early, but would love to hear what you think—what you like, what is missing. Appreciate any time you take to try it out. Nikolas  ( 3 min )

    How to Store Polymorphic Objects in C++ STL Containers?
    Introduction Can we store polymorphic objects by value in C++ STL containers? This topic often arises among C++ developers, particularly with the challenges posed by object slicing when dealing with base and derived classes. The crux of the issue lies in the behavior of STL containers and how they handle objects. In C++, when we store derived class instances in a container that holds base class objects by value, object slicing occurs, which results in the loss of the derived class-specific behaviour. This article aims to explore this concept specifically within the context of C++11 and later revisions, dissecting the challenges and potential approaches. Understanding the Slicing Problem When you store a derived class object in a container designed to hold objects of its base class by value…  ( 5 min )

    Securing Temporary Credentials in AWS: What You Should Be Doing But Probably Aren’t
    🔐 Temporary credentials in AWS are powerful—but also widely misunderstood. They allow developers and systems to access AWS resources without relying on long-lived access keys. But just because they expire doesn’t mean they’re safe by default. In this post, I break down: ✅ When and why to use temporary credentials 🧱 Where things go wrong (over-permissive roles, lazy session durations…) 🔒 Best practices for keeping temp creds secure 🧠 Advanced use cases like federation and IAM Roles Anywhere I’ve seen real-world setups where: Temp credentials lasted 12 hours Were used with AdministratorAccess In CI/CD pipelines with no monitoring That defeats the whole point of ephemeral access. Should Be Doing 🔸 Use least privilege roles Scope your roles tightly and use IAM condition keys like aws:SourceIp. 🔸 Shorten session durations 15–30 minutes is more than enough for most automation tasks. 🔸 Log STS usage with CloudTrail Every AssumeRole or GetSessionToken should be traceable and alertable. 🔸 Require MFA where appropriate Especially for sensitive role assumptions—break-glass or prod access. 🔸 Automate responsibly Don’t reuse temporary creds or store them insecurely in config files. Use the SDKs properly. For non-AWS workloads (like on-prem apps), IAM Roles Anywhere lets you issue short-lived AWS credentials using signed certificates. It's a powerful addition for hybrid setups, but comes with its own set of guardrails. The original article goes deeper into: Federation setups with Okta or AzureAD Example real-world misuses (and fixes) Credential rotation strategies 👉 Read the full guide here Let me know: How is your team managing AWS access today?

    Why does Swift have issues with opaque types for variables?
    When diving into the Swift language, especially for those new to the community, understanding how the Swift compiler treats opaque type declarations can be confusing. In your example, you're encountering a common scenario that many developers face when dealing with opaque types in Swift. Let's clarify this by breaking down your code and explaining why the behavior you're seeing is occurring. Understanding Opaque Types in Swift Swift's opaque types, introduced with the some keyword, allow developers to specify that a function will return a value conforming to a specific protocol without revealing its exact type. This is particularly useful for abstracting away implementation details while still adhering to protocols. In your code: protocol Animal {} class Dog: Animal {} func getMeADog() -…  ( 5 min )
    What is FTP? File Transfer Protocol
    At its core, FTP is a standard network protocol used to transfer files between a client and a remote server. Introduced in the early days of the internet, it was originally designed to simplify data sharing across ARPANET. Today, its primary use remains the same—allowing users to upload, download, and manage files between devices and systems across networks. While web browsers offer limited FTP support, professionals often turn to dedicated tools like FileZilla and Cyberduck to handle more advanced workflows. An FTP session typically initiates two connections: Control Channel: Handles command exchange and session setup. Data Channel: Transfers the actual file content. This dual-channel approach allows FTP to streamline complex file operations, enabling simultaneous uploads and downloads wi…  ( 4 min )

    Common SQL Mistakes and How to Avoid Them
    Structured Query Language (SQL) is an essential tool for working with databases, but even seasoned developers sometimes make mistakes that can lead to slow queries, inaccurate data, and inefficient systems. When summarizing data, the GROUP BY clause organizes information into meaningful groups. However, misusing GROUP BY can lead to incorrect results—sometimes without obvious errors. A database tracks employee salaries per department. Someone writes: sql To summarize salaries by department, the query should be: sql sql Only group necessary columns—non-grouped columns need aggregate functions. Use HAVING instead of WHERE for filtering grouped results: sql During testing, SELECT * is quick and handy. But in production? It slows queries, overloads networks, and makes applications harder to maintain. sql sql Explicitly specify needed columns instead of SELECT *. Use LIMIT for large queries: sql sql sql Indexes speed up data retrieval, but poorly designed indexes can slow down updates, inserts, and deletes. sql A better strategy: sql Index columns frequently used in WHERE clauses. Avoid over-indexing, which slows write operations. Use EXPLAIN or ANALYZE to check query performance: sql Use composite indexes only when queries filter by multiple columns: sql NULL values represent missing information, and if not handled correctly, they can cause errors or misleading results. This query calculates average salaries: sql Ensure NULLs are accounted for: sql sql Use IS NULL and IS NOT NULL to prevent logic errors. Replace NULLs using COALESCE() or IFNULL(): sql Validate NULL handling in reports to avoid misleading calculations. SQL mistakes can affect speed, accuracy, and system stability. But with the right practices, you can write efficient, optimized queries that scale well. GROUP BY must include all non-aggregated columns to avoid incorrect grouping. Never use SELECT * in production—fetch only required data. Index smartly, targeting commonly searched fields. Handle NULLs carefully, ensuring accurate calculations.  ( 4 min )

    🐧 Why I switched to Linux (and don’t regret it a second)
    When I first thought about switching from Windows to Linux, the main reason was simple — I want to control my computer. ⚙️ I love to automate everything One of the main reasons I chose Linux is the ability to automate everything. Every update, every new package — I decide what and how to install. This isn’t tied to forced downloads like in Windows. This is my freedom. 🌍 A world of options Linux gives you a huge variety of distributions, each suited to different needs. It’s like a builder where you choose what you need: I started with Ubuntu, because it’s stable, user-friendly, and has good documentation. But now I’m getting more interested in Arch and Fedora. I’ve realized that in Linux, it’s easy to switch between distributions, migrate between them, and adapt the system to your needs. 💻 Tech and CTF My passion for CTF and cybersecurity gave me even more reasons to switch to Linux. This system provides me with the tools to work with security, set up virtual machines, create test environments, and perform various attacks. You can’t achieve that in Windows, not to the same extent. Linux is a system for people who not only want to use technology but also understand it from the inside. For me, it’s not just an operating system, it’s a tool for growth and self-expression. 🌟 My freedom After switching to Linux, I felt that I was finally in control of my system. It’s not just an OS, it’s an environment that allows me to build, optimize, and use my computer the way I need. 🚀 Final thoughts If you’re tired of your computer not being yours, try Linux. A system where you decide how everything works. Where you can customize everything, automate it, and learn. It doesn’t matter if you’re a beginner or an experienced user — Linux has something for everyone.

    Bypass WhatsApp Template Limits with a Button-Triggered Formatting Flow
    Summary WhatsApp imposes a 24-hour customer-service window during which you can send any message; outside of it, only template messages (unformatted) are allowed. Goalmatic.io needs to let users send richly formatted content (articles, poems, etc.), so we built a two-step workaround: Template Send: Strip formatting and send via a WhatsApp template. On-Click Upgrade: Include a “Get Formatted Text” button in the template. When the user clicks, the 24-hour window reopens, allowing us to send the original, fully formatted message. Below is an end-to-end example in Node.js using the WhatsApp Cloud API. WhatsApp’s customer-service window rules mean: Within 24 hours of a user message, you can send any content (text, media, formatted). After 24 hours, only template messages (unformatted, pre-app…  ( 5 min )
    How to Handle Errors in SwiftUI View Model Effectively?
    Introduction Troubleshooting errors effectively in your SwiftUI application can be challenging, especially when they aren't caught where you expect them to be. In this article, we will explore common pitfalls in error handling when dealing with a view model in SwiftUI. We will focus specifically on how to ensure that errors thrown from your view model can be gracefully handled at the view level. Understanding the Issue In Swift applications, especially those using SwiftUI, it can sometimes occur that errors that are thrown from a view model do not propagate to the view layer. This can lead to confusion as you may not see the expected error messages in your user interface. In your case, while the error logging from the network layer indicates that an error is being produced, the error isn't…  ( 5 min )
    A Developer’s Guide to Browser Storage: Local Storage, Session Storage, and Cookies
    When developing web applications, storing data in the browser is essential for maintaining user sessions, saving preferences, and improving performance. Three common methods for client-side storage are Local Storage, Session Storage, and Cookies. While they serve similar purposes, they differ in data persistence, size limits, and accessibility. This article will explore the differences, advantages, and best use cases for each storage method. Local Storage is a browser-based storage mechanism that allows web applications to store key-value data persistently on the user’s device. The stored data does not expire and remains available even after users close and reopen the browser. ✔️ Persistent Data — Data is stored permanently until manually deleted // Storing data in Local Storage localStora…  ( 5 min )

    Back After a Break — Building Something Meaningful!
    Hey Devs! 👋 Yeah, I know… it’s been a while 😅 LearningTrackApp (name still under construction 😅) So this new app I’m building is a platform made for NGOs — specifically the ones that teach underprivileged kids. The idea is to help them keep track of their students’ progress, batch sessions, timings, names — basically everything important in one place. It’s simple, but I think it’s gonna be really useful. The app has a few different roles to keep everything organized: Super Admin – can access and manage all the NGOs. Admin – manages just their own NGO. Supervisor – the on-site person ensuring sessions are running smoothly. Volunteers – the awesome people who teach the kids. Students – well, this one explains itself 😄 That’s pretty much what I wanted to share for now. I genuinely feel like this app can be something impactful, and I’m excited to build it step by step. I’ll be posting more about the tech, my role, and the challenges I face in the next few posts. Until then, peace out ✌️  ( 3 min )

As society advances and individuals are learning to communicate less and less in person, the notion of "ghosting" - the often irreversible, severance of once deep social connections without reciprocity or explanation - becomes an all too familiar reality. Unfortunately, when individuals are "ghosted," they oftentimes face emotional trauma with rumination on what they did to deserve such a departure from their existence.

    Clean SQL with Comments: Syntax and Practices for All Engines
    Writing clean SQL is about more than just correctness—it's about clarity. SQL comments help you communicate with others (or your future self) by adding context, notes, or temporarily disabling code. Let’s explore how to use comments effectively. Using Comments in SQL Two Main Types: Single-line -- Pull users created in the last week SELECT * FROM users WHERE created_at >= CURRENT_DATE - INTERVAL '7 days'; Multi-line /* Use this version for reporting Includes only verified accounts */ SELECT * FROM accounts WHERE verified = TRUE; Why and When to Comment Helpful When: Writing complex logic Sharing scripts with a team Disabling old queries during testing Avoid: Leaving sensitive info Explaining simple queries Letting comments go stale Different Engines, Different Capabilities MySQL: Supports versioned comments /*! */. PostgreSQL: COMMENT ON lets you label schema elements. SQLite: Keeps it basic and portable. SQL Server & Oracle: Great for documenting stored code and schema. FAQ How do I add comments in SQL? Use -- for quick notes or /* */ for multiple lines or blocks. Yes—wrap code in /* */ and it won’t run. Yes, both styles are widely supported with small engine-specific features. Only if they include secrets or mislead developers. Keep them clean and relevant. Conclusion SQL comments don’t take much effort but make a big difference.

    DevOps in Embedded Software? Let’s Be Honest: It Doesn’t Really Exist
    When people talk about DevOps, they usually mean something very specific: development teams continuously building and shipping code, and operations teams running and scaling that code in production—usually in the cloud. CI/CD pipelines automatically build, test, and deploy code through staging, QA, and production environments. The boundaries and responsibilities are clear. But what happens when you try to apply this same DevOps concept to embedded software development? Spoiler: it doesn’t fit. At least not in the way most people mean when they say “DevOps.” In embedded systems, developers write software that runs on physical devices. Their workflow looks more like this: They may test features on sample boards, and in some setups, even flash the software to hardware themselves. But that’s w…  ( 4 min )

    How to Document Constants in Python Effectively?
    In Python programming, it's common to define constants that are used throughout your code. These constants, stored in a file like constants.py, can help keep your code organized and make it easier to update settings or values in the future. However, when documenting functions that use these constants, developers often face the dilemma of whether to refer to the constants directly in the documentation or use their values instead. Why Use Constants in Python? Constants like PATH_DATASETS = "data/datasets/" and WIDTH = 416 serve as fixed values that can be reused across multiple functions in your program. This practice enhances code readability, maintainability, and minimizes the risk of introducing errors when changes are needed.

    An Introduction
    👋 Hello Dev Community — From Guyana with Love! Hey everyone! I'm Nathaniel, a developer and computer science student from Guyana — a small country on the South American mainland. I’m passionate about writing clean code, building full-stack applications, and diving deep into topics like JWTs, web architecture, and system-level programming in C. But beyond that, I’m also deeply interested in how technology is growing (or struggling) in Guyana — from internet access to education to the startup scene. To share dev articles and tutorials, especially things I’ve learned or struggled with as a student and builder. To spotlight Guyana’s tech space, which I think deserves more global attention and internal discussion. To connect with other developers, both in the Caribbean and internationally, and learn from their stories as well. I’ve noticed there's not a lot of content on Dev.to about tech in Guyana, so I want to help change that. Whether you’re here for tutorials, dev opinions, or insights into building a tech career from a small country, I hope my posts can add value. Feel free to reach out, share your thoughts, or even suggest topics you'd like to see discussed.  ( 3 min )

    I originally posted this post on my blog. I didn't pay for the most expensive hamburgers I've eaten. An ex-employer did. When I say "most expensive," I mean the same greasy $5 or $10-dollar hamburger from a food truck or a corner in a busy street. But they felt expensive because I ate them while working overnight. In a past job, when my team was lagging behind the self-imposed deadlines of sprints, higher-ups told us: "This sprint is behind schedule. What are you going to do? You're a self-managed team, so decide that by yourselves. But if I were you, I'd choose to work overtime to keep up." "You're a self-managed team" was their subtle way of telling us to work extra hours, without accepting any responsibility. We didn't have any say in what tasks to do and how. We were only a self-managed team when it came to choosing to work overtime. They didn't pay us for that extra time. They only bought us hamburgers. And, when someone raised their concerns about the quality of those hamburgers, they told us we should be grateful because other companies buy their employees nothing to eat. If you're told you're part of a self-managed team, read the fine print. Look for signs of real self-managed teams: Look at job descriptions. Connect with people already working there. Ask follow-up questions during interviews. Otherwise, they might expect you to work overtime without compensation or just buy you an hamburger.

    Introducing Secure MCP-gRPC: Enterprise-Grade Security for AI Model Communication By Matthew Stanton | May 12, 2025 TL;DR: Secure MCP-gRPC is an open-source project that adds an enterprise-grade security layer to the Model Context Protocol (MCP), enabling AI models to communicate securely with each other and external tools. It features advanced authentication, comprehensive telemetry, and real-time visualization of model interactions. As organizations increasingly deploy sophisticated AI systems, models need to communicate with each other and with external data sources. The Model Context Protocol (MCP) has emerged as a powerful standard for this communication, but enterprise-grade security and observability features are critical missing pieces for production deployments.

    Why TypeScript Enums Increase Angular Bundle Size and How to Fix It
    When optimizing Angular applications for performance, developers often overlook a silent culprit: TypeScript enums. While enums improve code readability and type safety, they introduce unexpected overhead in your final JavaScript bundle. This can lead to larger file sizes, slower load times, and diminished performance, especially on mobile or low-bandwidth connections. In this article, we'll explore how enums contribute to bundle bloat, why Angular's build tools struggle to optimize them, and which alternatives you can use to write cleaner, faster, and more efficient code. An enum is a TypeScript feature that lets you define a set of named constants. For example: export enum UserRole { Admin, Editor, Viewer } Under the hood, this compiles to something like: "use strict"; var UserRo…  ( 5 min )

    Destroy service for rxjs observables
    🧩 Implementation: @Injectable() export class DestroyService extends Subject { ngOnDestroy() { this.next(); this.complete(); } } 🧩 Question: ngOnDestroy() in this pattern? Even though DestroyService is a service and extends Subject, how does Angular still invoke ngOnDestroy()? 💡 Answer: Even though DestroyService extends Subject (which is not a component or directive), Angular still calls its ngOnDestroy() method if the service is provided at the component level. 🔑 Why ngOnDestroy() Gets Called in a Service ✅ Angular will call ngOnDestroy() if: The class implements OnDestroy AND it is a provider on a component or directive Example: @Component({ Then Angular treats the service like a directive-level provider, and because it has ngOnDestroy(): 🧠 Why It Works Even Though It Extends Subject Subject has no ngOnDestroy(). That's fine. You're extending Subject and adding ngOnDestroy() yourself. Angular doesn’t care that it extends Subject — it just sees: “This class was provided in the component” “It has ngOnDestroy()” ✅ Call it when the component is destroyed 🔁 Summary DestroyService is a service, but it's scoped to the component using providers: [DestroyService] It has a custom ngOnDestroy() method Angular calls ngOnDestroy() on component-scoped providers So you get an automatic, injectable "destroy notifier" for use with takeUntil() This is a neat Angular trick that combines: Lifecycle hooks Dependency injection RxJS into a reusable, composable unsubscribe mechanism.

    🌐📘 Understanding the CSS Box Model with a Simple Example 😊💻
    The CSS Box Model is one of the most important concepts in web design 🧱. It describes how elements are structured on a webpage — every HTML element is treated like a box with layers: content, padding, border, and margin. 💡 What I Made I created a simple webpage using HTML and CSS ✨. It shows a box with the message "Hello Kts". You can view the live demo here: The design is simple but effective — a colored box with space inside and outside, and a border to highlight the shape. 🧠 How the Box Model Works in My Project: Margin: It adds space outside the box (like a buffer from the edges) ➡️ Padding: It adds space inside the box around the text, making it look neat 🧍‍♂️ Border: This creates a clear outline around the box ⚫ Background color: I used a brown background to make the box stand out 🟤 🚀 Why It Matters? Understanding the box model helps you: Control spacing and alignment 🧩 Avoid layout issues or overlapping elements 🚫 Make your design clean and professional ✨ This project helped me understand the basics of styling elements in CSS. It’s a small step, but a strong foundation for building beautiful websites! 🛠️🌟  ( 3 min )

    Amazon Q Quack The Code: Pompeii Time Out
    This is a submission for the Amazon Q Developer "Quack The Code" Challenge: That's Entertainment! I built a text adventure game inspired by the history of ancient Pompeii. I believe my text adventure game differentiates itself by adding new features to the UI as you progress through the game. The first feature is a whole new text console that enables you to control and connect the two player characters between time. And the second is a map on the UI enabling you to better understand you position in the game. https://aproulx232.github.io/pompeii-time-out/ https://github.com/aproulx232/pompeii-time-out I used Amazon Q as a visual studio code extension. I have had extensive professional experience with other AI coding tools such as Cursor and Cline. Amazon Q was extremely easy to install and get up and running with the context I already have around AI tools. I found I used the chat feature the most, the same way I would use Cursor chat. The responses and code edits seem to be on par with Cursor. However, multiple times the chat context got stuck and would try over and over to write to my files with no success and no errors to work with.  ( 3 min )
    Is AI the New Oil? We Need to Talk About What It’s Costing Us
    We talk a lot about how smart AI is getting. Not in some sci-fi dystopia. In a real, physical, “it’s-happening-now” kind of way. Every time we ask a model to summarize a doc or spit out a joke, there’s a real-world cost i.e. electricity, water, hardware, minerals. And it adds up. Fast. 🔋 Power Hungry: How Much Juice Does AI Really Need? Let’s start with the basics. Training GPT-3 used up more than 1,200 megawatt-hours of electricity. That could’ve powered over a hundred homes in the U.S. for a full year. Now take GPT-4. That one? Easily 50x more, depending on the estimate. We’re talking small-city-level energy. And guess what?

    Why Does Go Allow Comparing Integer with String?
    In this article, we will explore why Go allows type comparisons that might initially seem surprising, particularly in instances like comparing an integer to a string. We'll explain the underlying mechanisms of Go's type system and how the language handles such comparisons without raising errors or panics. Understanding Go's Type System Go is a statically typed language, which means that the types of all variables are known at compile time. When you define a variable, its type must be explicitly declared or inferred, leading to a robust type safety framework. However, Go introduces a unique feature with the any type, which can hold a value of any type. This flexibility plays a crucial role in our example. The Role of the any Type In your provided code, we see the variable hello is declared …  ( 5 min )

    Avoid Getting Blocked! Implementing Amazon Price Monitoring with Python and Proxy IPs
    In the competitive world of e-commerce, monitoring prices on platforms like Amazon is crucial for businesses and savvy shoppers alike. However, scraping data directly from such websites can lead to IP bans and access restrictions. To mitigate these risks, using Python in conjunction with proxy IPs offers a safe and effective solution for price monitoring. Why Use Proxies for Amazon Price Monitoring? Anonymity: Proxies mask your real IP address, making it difficult for websites to track your scraping activities. import requests proxy = { http://your_proxy_ip:port", http://your_proxy_ip:port" def get_price(url): # Find the price element (this may vary based on the product page) url = 'https://www.amazon.com/dp/your_product_id' Static and Residential IPs: These are less likely to be flagged by Amazon.

    Uniapp开发鸿蒙应用教程之自定义导航栏
    连续分享了几天的Uniapp跨平台开发鸿蒙应用教程的文章,相信大家对跨平台开发已经有了初步的了解,今天分享一下跨平台开发中的自定义导航栏。 在Hbuilder的初始化项目中是自带了导航栏的,这是一个全局的导航栏,它的样式设置和修改是在全局的配置文件pages.json中进行。 现在打开pages.json文件,在globalStyle中有一些关于导航栏的属性,我们尝试修改一下: { "pages": [ //pages数组中第一项表示应用启动页,参考:https://uniapp.dcloud.io/collocation/pages ], "globalStyle": { 然后看到导航栏已经发生了改变: 这样的修改很方便很便捷,但是好像只有颜色和文字这些基础的属性可以修改,很多时候我们需要在导航栏上添加一些组件,比如按钮或者搜索框。 对于这种情况,uniapp也提供了相应的设置方案,还是在pages.json文件中,当我们需要为某一个页面的导航栏添加组件,就在对应的path路径下设置style,style中有个titleNView属性就是为导航栏添加自定义组件,像这样: "path": "pages/index/index", 但是幽蓝君亲测这种设置方式在浏览器运行时可以正常显示,在鸿蒙中是无效的: 所以在鸿蒙开发中我们需要自己定义导航栏。 再次回到pages.json文件,这次将navigationStyle设置成custom,作用是取消原生的导航栏: "path": "pages/index/index", 然后打开需要自定义导航栏的页面,我这里就直接在首页index.vue中操作,实现逻辑比较简单,就是在页面顶部添加一个导航栏大小的组件,然后在其中添加搜索框,相关代码如下: style="width: calc(100% - 40px);background-color: white;height: 35px;padding: 0px 10px;border-radius: 18px;" .custom-nav-bar { / background-color: #f8f8f8; 导航栏背景色 / 其他样式属性 */ 看一下运行效果: 今天就以添加一个搜索框为例,大家如果需要自定义其他的样式也是类似的实现方式。 以上就是uniapp跨平台开发鸿蒙应用中的自定义导航栏,感谢大家的阅读。  ( 3 min )

    The 1% of Hacking Nobody Talks About… But Should
    Most people think hacking is just about tools, code, or some flashy terminal with green text flying by. But that’s not what makes a real hacker. Let me tell you what really matters—the part only 1% truly understand… Forget the tools for a second. Real hacking starts when you ask the questions nobody else is asking: "Why does this work like that?" "What happens if I try something they didn’t expect?" "What’s behind this system they don’t want me to see?" It’s about curiosity. Obsession. Even rebellion. Not following tutorials step-by-step, but breaking patterns and learning how systems truly work under the surface. I’m teaching myself Python and networking— Not because I want to show off, but because I want to understand how the internet and machines actually think. I’m not here to be just another script kiddie. I’m building a foundation. Quietly. Daily. I don’t want fame. I don’t want likes. I want leverage. I want to be the kind of person who sees through the system—and knows how to bend it. A silent weapon. Sharp, skilled, and always learning. Are you learning just to pass exams? Or are you learning to break limits? Be real with yourself. The world’s already full of followers. We need more builders, breakers, and thinkers. If you feel that fire too—the curiosity, the hunger to really understand—drop a comment. Tell me what you're working on. I’m still early in my journey, but I’m in it for real. Let’s learn.

    ARQUITETURA REST: PRINCÍPIOS, PADRÕES E APLICABILIDADE NO DESENVOLVIMENTO DE SISTEMAS DISTRIBUÍDOS
    RESUMO Palavras-chave: Arquitetura REST. Sistemas distribuídos. API. HTTP. Serviços Web. 1 INTRODUÇÃO 2 DESENVOLVIMENTO De acordo com Stein Junior (2021), REST surgiu da necessidade de criar interfaces simples e eficientes para a comunicação entre sistemas, principalmente via web. O autor afirma que "o objetivo era criar interfaces simples, escaláveis e independentes, facilitando a comunicação entre sistemas distribuídos por meio do protocolo HTTP" (STEIN JUNIOR, 2021, p. 10). A arquitetura REST é baseada na manipulação de recursos — objetos ou entidades de informação — que são identificados por meio de URIs (Uniform Resource Identifiers) e manipulados utilizando métodos HTTP padronizados, como GET, POST, PUT e DELETE. Fielding (2000) ressalta que uma das principais características do REST…  ( 6 min )
    How to Efficiently Use JAX for Numerical Pipelines
    Introduction In the world of numerical computing, transitioning from NumPy to JAX can offer significant performance benefits thanks to JAX's Just-In-Time (JIT) compilation and optimizations for GPU acceleration. However, this transition isn't always smooth for all operations, particularly for those that are heavily transformation-based, such as broadcast_to and moveaxis. In this article, we will explore why these functions may perform slower in JAX compared to NumPy and discuss best practices to optimize their usage. Understanding the Performance Discrepancy Why JAX May Be Slower for Basic Operations The performance of JAX can vary significantly depending on the operations being performed. While JAX is designed for efficient numerical computation and can excel in larger batch sizes and com…  ( 5 min )
    5 Common Workflow Automation Mistakes (And How to Avoid Them)
    Let’s not sugarcoat it—workflow automation should be simple. You sketch out a flow, wire up a few APIs, slap in a trigger, and boom: your job runs itself while you sip coffee. Except… not really. In reality, automation breaks. It misfires. It fails silently. And if you’re building workflows without a plan (I’ve done it), you’ll spend more time debugging than you ever saved. So here are 5 workflow automation mistakes I’ve run into—plus how I fixed them using Martini, a low-code automation platform that somehow gets it. 1. Only Building the Happy Path Raise your hand if you’ve built an automation that worked perfectly—until the first error. I’ve done it. Then I spent the next hour trying to figure out why a webhook timed out and brought down the entire flow. ✅ Fix: Build for failure first.…  ( 4 min )

    Bridging Brilliance and Blunder
    Beneath the noise of internet forums and viral memes, a fascinating reflection stares back at us. It juxtaposes artificial intelligence—consistent, precise, and relentlessly efficient—with what users affectionately term "natural stupidity," the charming catalogue of everyday human errors. This humorous contrast isn't merely jest; it captures the essence of our paradoxical relationship with the technology we ourselves have crafted. In recognising both our ingenuity and our imperfections, we frame a dialogue that reveals profound truths about humanity, technology, and our entwined destinies.

    How to Send Traces Using Scala and OpenTelemetry
    How to Send Traces Using Scala and OpenTelemetry When working with distributed systems, traceability is crucial for understanding system behavior. If you are using Scala and OpenTelemetry to send traces, you may encounter some challenges, particularly if your traces are not appearing in the tracing backend like Zipkin or Tempo. Why Might Traces Not Be Sent? Traces not appearing in your tracing backend can be attributed to several issues. These issues might stem from misconfiguration in your OpenTelemetry setup, lack of proper attributes, or even potential threading issues with Scala. It’s essential to verify that the OpenTelemetry collector is up and running and that the endpoint is correctly configured, which you have indicated is ready. In Scala, the ThreadLocal context propagation can b…  ( 5 min )

    Validate Your Env at Build Time — with Custom Rules Powered by Amazon Q Developer
    This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line I created envguardr, a CLI tool that validates environment variables at build time. It’s useful for projects where .env files or runtime checks aren't enough. It handles types, required fields, and default values, but I felt it needed more flexibility. To address that, I enhanced the underlying validation package valitype by adding support for custom validators. This was one of the ideas suggested by Amazon Q Developer during the challenge. That single improvement unlocked a range of advanced use cases. Install envguardr globally: $ npm install -g envguardr Create an env.schema.js file with custom validation logic: module.exports = { API_KEY: { type: 'custom', validator: (v) => /^[a-z0-9]{16}$/.test(v || ''), errorMessage: 'API_KEY must be 16 alphanumeric characters', required: true } } Then run: $ envguardr validate env.schema.js envguardr with a custom schema validation for API_KEY: https://github.com/fontebasso/valitype https://github.com/fontebasso/envguardr This challenge was my first experience with Amazon Q Developer, and I was genuinely impressed. It’s exactly the kind of tool I always felt was missing for developers working with AI. Amazon Q Developer was able to read my codebase, understand its context, and assist in meaningful ways. It helped me improve typing, write better tests, fix subtle lint issues, and explore useful new features. From the several improvements it suggested for valitype, I chose to implement custom validators. That feature alone made envguardr much more powerful, giving it the flexibility needed for advanced configuration validation.  ( 3 min )

    What is the difference between Test_two and A_Package::Test_one in Perl?
    In Perl programming, naming conventions for symbol table entries can seem confusing at first glance, especially when we encounter entries like Test_two and A_Package::Test_one. In this article, we will explore the distinctions between these two styles of naming and how they impact the scope and accessibility of your subroutines. Understanding Symbol Tables in Perl In Perl, every package has its own symbol table, which serves as a collection of all the symbols (subroutines, variables, etc.) defined within that package. This allows for the organization of code into different namespaces, ensuring that subroutine names do not clobber each other in larger applications. The Significance of Test_two When we define a subroutine using the name Test_two, like this: *{"Test_two"} = sub{"Testing Two…  ( 4 min )

    How JavaScript Executes Code: Understanding Execution Context and the Call Stack
    JavaScript is a single-threaded, synchronous programming language at its core, but it handles asynchronous operations through clever mechanisms like the event loop. To truly understand how JavaScript works under the hood, you need to grasp two fundamental concepts: execution context and the call stack. An execution context is an abstract concept that holds information about the environment where JavaScript code is executed. There are three types of execution contexts in JavaScript: Global Execution Context: Created when the JavaScript engine first starts executing your code Function Execution Context: Created whenever a function is invoked Eval Execution Context: Created inside an eval function (rarely used) Each execution context has two phases: Creation phase Execution phase During the c…  ( 5 min )

Basically, they give schools one simple platform to track and organize all their business relationships — no more messy spreadsheets. Think of it like a behind-the-scenes CRM for higher education, and I get to help build it. What’s even more exciting? The tech stack. I’ll be working with: TypeScript Tailwind CSS React Router Vite Node.js Docker Microsoft Azure Yes — full-stack cloud engineering with a taste of containerization and cloud infrastructure. I’ll be starting out on front-end tasks, but eventually I’ll get to dive into cloud stuff too. With all the buzz around cloud computing, I can’t wait to roll up my sleeves and get my hands dirty in Azure. 🧠 How I’m Preparing i took an IBM JavaScript course on Coursera. Followed a Scrimba course to brush up on my JS fundamentals. Built a few practice projects to get comfortable with React (since I’ve never used it before). Started learning TypeScript ,also new territory for me, but I'm determined to hit the ground running. 😅 The Honest Truth I’ve heard people say your first tech internship humbles you. That thought stays in the back of my mind, and it does freak me out a bit. What if I struggle? What if I fall behind? But here’s what I do know: I’m giving it everything I’ve got. I’m showing up ready to learn, ready to grow, and ready to take the hits and bounce back. This internship is my stepping stone — not just to sharpen my skills, but to prove to myself that I belong here. So here’s to embracing the unknown, taking the leap, and letting the learning begin. Let’s see where this road leads. 🌥️👨🏾‍💻  ( 4 min )
    Upgrade Your Angular Application Effectively!
    One task you may not do every day, but will eventually face as an Angular Developer, is updating your Angular application's version. At first glance, it may seem simple — especially since the official documentation provides a step-by-step guide. However, that guide won’t cover everything you’ll encounter during a real-world migration. In this post, I’ll share key tips to help you upgrade your Angular project more efficiently and avoid common pitfalls. Before starting any migration, it's essential to have a solid Git workflow. I recommend using a Git Flow strategy: Keep your main branch stable and production-ready. Create a dedicated migration branch (e.g., migration/angular-17). Every time changes are approved on main, merge them into your migration branch to keep it up to date. This allow…  ( 4 min )
    How to Export a Swift Package as an XCFramework
    If you're working with Swift packages and need to convert your Swift project to an XCFramework, it's essential to follow a proper procedure since your customer requires it in that format rather than as a Swift Package Manager (SPM). In this article, we’ll explore the steps needed to export your Swift package—specifically the one found at Revenuemore—as an XCFramework. Why Use XCFramework? XCFrameworks are a modern approach to distribute binaries across platforms with compatibility for different architectures like iOS, macOS, and tvOS. They address the shortcomings of traditional frameworks, especially when it comes to handling multiple build targets and supporting both simulator and device architectures in a single package. This makes them an ideal choice for developers aiming for broad co…  ( 4 min )
    I Integrated Local AI into Spacemacs — Here's How It Works
    A month and a half ago, I barely knew anything about AI. Now I’ve got Mythomax, LLaMA 3, and OpenHermes all running locally — fully integrated into my Spacemacs workflow. This isn’t just a fun experiment. It’s a working system.

    How to Prevent, Predict, and Fix Relationship Conflicts
    You would think that a small comment you made about your partner's outfit does not mean anything. However, that small comment has the potential to become a trauma for your partner. In fact, any comment that comes out of your mouth has the potential to scar your partner for life. Therefore, it is important to know yourself, know the evil and good side of your personality, know when each of those are in command of your speech. This knowledge will in turn make you a safe space for your partner, and will also make you someone that is able to prevent conflicts; "If I am aware of my mood I am able to manipulate my speech". Predict conflicts; "If I am at my worst mood the words that come out of my mouth will be harmful". Fix conflicts "I said certain things while I was not at my best cognitive ab…  ( 4 min )

    How to Exit a Bash Script with an Error Message?
    When scripting in Bash, it's common to want to exit a script gracefully when an operation fails. This is essential for ensuring that your script does not continue to run in an erroneous state. In this article, we’ll explore how to exit a Bash script with a custom error message and discuss some common pitfalls that may arise in the process. Understanding the Basics of Exit Codes in Bash Bash scripts use exit codes to indicate completion status. A successful command returns an exit code of 0, while a failure returns a non-zero exit code. You can capture this behavior using conditional statements. For example, command || echo 'Error message' will output the error message if the command fails. Exiting Scripts on Command Failure If you want to exit the script when a non-existing command is invo…  ( 5 min )

    Building Tools for ANT National Transit Authority Matrícula Data
    In Ecuador, public data systems are becoming increasingly accessible, and developers have a unique opportunity to create tools that make this data more user-friendly. One such system is the ANT matrícula, which allows individuals to check the legal status of a vehicle by entering its license plate. This system is crucial for verifying vehicle registration, ensuring that taxes are paid, and checking whether there are any fines or restrictions on a vehicle. While the ANT does not provide a public API, developers can still create tools that simulate this functionality. For instance, a backend system can be built using technologies like Node.js, where users can input a license plate number and receive data about its registration status. This not only helps users avoid scams when buying a used car but also assists businesses in managing vehicle fleets or ensuring compliance with national regulations. However, it's important to follow ethical guidelines when accessing public data. Developers should ensure that personal data is never stored without consent and that scraping or data collection is done in compliance with legal standards. Creating tools based on the ANT National Transit Authority matrícula system brings significant value to users, especially by saving them time and offering an easy way to confirm the legal status of a vehicle without having to visit government websites. By building accessible and useful tools, developers can support transparency, safety, and efficiency in Ecuador's transportation system.  ( 3 min )

    From Beginner to Builder: My Journey Creating an Open-Source App (as a non-dev)
    Back in 2015, I wasn’t a developer (and still now). I had no formal training in coding. But I loved language learning tools, and I came across a neat pronunciation tool on a CD-ROM that came with the Oxford Advanced Learner’s Dictionary 9th Edition. I didn’t know it then, but trying to tinker with that app would kickstart my journey into programming — one that would eventually lead to building iSpeakerReact, a modern, open-source language learning tool powered by React and Electron. This post is a reflection on that journey — the mistakes, the revamps, and the little wins that kept me going. Before iSpeakerReact got its current name, it was just called iSpeaker.

    Is create-react-app Deprecated? What You Need to Know in 2025
    For years, create-react-app (CRA) was the go-to tool for spinning up new React projects. With a single command, you could scaffold a full React application complete with Webpack, Babel, ESLint, and more—all without touching a configuration file. But as the React ecosystem rapidly evolves in 2025, developers are asking: Is create-react-app deprecated? 🛑 The Short Answer: Not Officially, But Practically... Yes create-react-app has not been officially deprecated by its maintainers, it’s clear that active development has stalled. The React team has shifted focus to modern full-stack frameworks, and CRA is no longer the recommended way to start a new project. In other words: CRA still works, but it’s outdated, and better options now exist. 1. Stagnant Development 2. No Server-Side Rendering (S…  ( 5 min )

    Would a plug-and-play abuse protection toolkit be useful beyond Stripe Radar?
    Payment is one of the problems in online business and Stripe quick emerged as the main payment system despite seen a fair amount of complains. After Marc Louvion released ByeDispute, I was intrigued that Stripe was not covering that and so ended up having a tunnel on card fraud and how Stripe works. Yes Stripe Radar exists and cover some fraud cases but does not cover everything and there have been complains of account flagging despite it or a modification of the fraud detection algorithms that blocks all in coming transactions without any possibilities to stop that. But also fake signups, trial/refund cycling, scraping, or promo code abuse. Enterprise tools are overkill, and DIY solutions eat up dev time. So I wonder if a more general product that check One-trial-per-user, detect disposable email and scraping, have behavioral bot checks, prevent promo/referral abuse and chargeback/refund patterns, ... Would actually be more interesting. When flagging you would get the reasons and the solution can be disactivated at any time. Maybe even a community side with common ban list on fraudulent payments or disputes. On top of that a dashboard to follow all of this. Would something like this be helpful or just more noise? Curious if others have had to roll their own systems for this.  ( 3 min )

    Mental Models for Vector Dimensions
    Personalized insight for intuitively understanding vector dimensions Definition: Independent directions along which an entity can move or shift. 4D Illustration: Four available paths: East/West (X-axis) North/South (Y-axis) Up/Down (Z-axis) Forward-only in time (Time axis) Analogy: Imagine controlling a toy car in a video game: Use left/right buttons to steer (east/west). Use forward/back buttons to accelerate or reverse (north/south). Press a jump button to lift off ramps (up/down). A race timer shows elapsed time, counting forward only. Definition: Distinct properties required to describe an entity fully. 4D Illustration: Four attributes defining a profile. Analogy: A game character defined by Strength, Agility, Intelligence, and Charisma. The vector (7,5,9,3) conveys the complete trait set instantly. 2. Time as the Fourth Dimension Adapting Each Model to Include Time: Physical View Analogy: Characteristic View Analogy: 3. What Does a 2D Vector Represent?

    Centralize HTTP Error Handling in Go
    Originally posted here In this short post, I'll share with you a simple pattern I use to centralize error handling for my HTTP handlers. If you've written any amount of Go HTTP servers, you've probably gotten tired of writing the same error handling code over and over again: func SomeHandler(w http.ResponseWriter, r *http.Request) { data, err := fetchSomeData() if err != nil { http.Error(w, "Failed to fetch data", http.StatusInternalServerError) log.Printf("Error fetching data: %v", err) return } // More if-err blocks... } This code is repetitive, error-prone, and clutters your handlers with boilerplate instead of business logic.

    Singleton Design Pattern: Explained Simply
    In software design, some objects are meant to be shared across the entire application. Think of a configuration manager, a database connection, or a logger. You don’t want to create multiple instances of these — just one that is reused everywhere. That’s exactly where the Singleton Pattern comes in. The Singleton Pattern ensures that a class has only one instance and provides a global point of access to it. It’s part of the Creational Design Patterns — patterns focused on object creation. Think of a government. There’s only one Prime Minister (ideally 😄). If you try to create a new one, it should refer to the existing one. Database connections Logging services Config/environment managers Thread pools Caching mechanisms class Singleton { constructor() { if (Singleton.instance) { return Singleton.instance; } this.timestamp = new Date(); Singleton.instance = this; } getTime() { return this.timestamp; } } // Usage const a = new Singleton(); const b = new Singleton(); console.log(a === b); // true console.log(a.getTime() === b.getTime()); // true class Singleton: _instance = None def __new__(cls): if cls._instance is None: cls._instance = super(Singleton, cls).__new__(cls) cls._instance.timestamp = "Created at instance creation" return cls._instance # Usage a = Singleton() b = Singleton() print(a is b) # True Controlled access to a single instance Saves memory (especially useful for expensive objects) Can be lazily loaded (created only when needed) Global state can be hard to test Can violate Single Responsibility Principle In multithreading environments, needs proper locking (especially in Java/C++) Keep it stateless if possible Avoid abusing it like a global variable Be cautious in multi-threaded apps (use locks/mutexes) The Singleton Pattern is a handy tool when you need exactly one instance of a class to coordinate actions across the system. Use it wisely and you’ll make your application more efficient and structured.  ( 3 min )

Together, they provide powerful insights into your cluster’s performance. ## 🛠️ Prerequisites Azure CLI installed and authenticated kubectl configured to your AKS cluster Helm 3 installed A working AKS cluster bash helm repo add prometheus-community https://prometheus-community.github.io/helm-charts helm repo add grafana https://grafana.github.io/helm-charts helm repo update **Install Prometheus:** helm install prometheus prometheus-community/prometheus \ --namespace monitoring --create-namespace Install Grafana: helm install grafana grafana/grafana \ --namespace monitoring Access the Grafana UI: You can port-forward and access Grafana at http://localhost:3000: kubectl port-forward svc/grafana 3000:80 -n monitoring **Login using:** Username: admin Password: (from step 4) **📊 Importing Dashboards** Once inside Grafana, go to "Dashboards > Import" and use IDs from Grafana.com like: Kubernetes Cluster Monitoring: 315 Node Exporter: 1860 **💡 Lessons Learned** Always install Prometheus before Grafana if you want dashboards to auto-discover data sources. Use persistent volumes for Prometheus and Grafana in production. Set up alerts for critical metrics like pod restarts or high CPU usage. I’m planning to extend this by: Setting up AlertManager Integrating with Slack for alerts Enabling SSL and Ingress for Grafana Stay tuned! 👀  ( 3 min )

    How to Perform Row-Wise Aggregation in DuckDB Using SQL?
    Introduction In data analysis, it's common to aggregate data from various tables. In your case, you're working with two fact tables, CDI and Population, in DuckDB. You want to perform a filtered aggregation on the Population table based on values from each row in the CDI table. This kind of task can be achieved using ANSI SQL, and I’ll walk you through how to implement it. Understanding the Tables Before diving into the SQL query, let's break down the tables you are using: CDI Table: This contains various categorical data that you'll be using as filters.

    What is redis pipeline
    Introduction Redis is a fast, in-memory data store widely used for caching, message brokering, and real-time analytics. While Redis is incredibly efficient, network overhead can become a bottleneck when a large number of commands are sent sequentially. This is where Redis pipelining comes in. Redis pipelining allows a client to send multiple commands to the server without waiting for individual responses. The server processes the batch of commands and returns all responses in a single reply, significantly reducing the latency caused by round-trip communication. If you are struggling to remember redis commands then this cheatsheet might help you. Redis pipelining offers several advantages: Reduced Latency: By sending multiple commands in a single request, you cut down on network round-tri…  ( 4 min )
    Two of My Favorite Custom MCP Tools I Use Every Day
    My Two Favorite MCP Tools - True Game Changers I've been building custom MCP tools for a month or so now, and just two of them have absolutely transformed how I work with Claude - they were the real 'aha!' moment for me and 'agentic' workflows.

    Gland: Beyond Protocol-Agnostic
    Hey everyone, I’m back again with another update from the world of Gland — and this one is kinda big for me. So far, I’ve talked a lot about Gland being protocol-agnostic. But recently, something shifted. Gland is not just protocol-agnostic anymore — it’s kinda framework-agnostic too. What does that even mean? Let’s be real: right now Gland doesn’t care whether you're using Express, Fastify, Hono, or literally anything else that can act like an HTTP server. You can swap them in and out with minimal effort. And I’m not talking about some theoretical plug-and-play thing. I mean actual working code. Take this simple example: glandjs/gland/main/samples/01-simple/src/main.ts In this setup, I’m using Express. But if you want Fastify instead?

    Goodbye pod install
    Introduction For years, React Native developers working on iOS have relied on one command more than any other: cd ios && pod install This command has been a staple for managing native dependencies in iOS projects. But in 2025, React Native is moving away from it—and for good reasons. If you’ve recently seen a warning like: "Calling pod install directly is deprecated in React Native" ...you’re witnessing a significant shift in how React Native handles iOS builds. React Native is undergoing a significant transformation, and part of that involves reducing reliance on iOS-specific tools like CocoaPods. Here’s why: CocoaPods is great for iOS, but React Native aims for true cross-platform development. The new architecture favors tools that work seamlessly across iOS, Android, and beyond.

    How to Find the Second Highest Student Average Mark in Java?
    Finding the second highest average mark among students can be a common requirement in many applications that deal with student data. In this article, we will explore a solution to find the student with the second highest average mark without creating any new objects. We will be using Java streams and our custom Student class, which holds information about each student such as their average mark, first name, last name, and date of birth. Understanding the Problem To tackle this problem, we need to follow a few key steps. First, we need to sort the list of students based on their averageMark. Since we want to find the second highest average mark, it is essential to sort the list in descending order. According to the problem's requirements, if two students have the same average mark, we shoul…  ( 4 min )
    I love finite-state machines:)
    Hi, my name is Anton. I'm a software developer specializing in cross-platform mobile development, currently working at a fintech company where I help build a neo-banking application. There's often debate about design patterns—do we really need them, or are they just outdated theory with little practical value in modern software development? I strongly disagree with the idea that patterns are unnecessary. In my view, having a solid foundation in theoretical concepts is extremely valuable. It's like recursion: you might not need it every day, but when you encounter a problem that is recursive in nature—like traversing a file system—you simply can't solve it effectively any other way. The same applies to design patterns. Some processes naturally fit certain patterns, and recognizing them allo…  ( 9 min )
    The Great MCP Aggregation Heist
    How Your Code Became Someone Else’s Goldmine In the thickening jungle of AI innovation, Model Context Protocol (MCP) aggregation services are rising like monolithic temples, promising universal access to tools and automation. On the surface, it sounds utopian—a meritocratic open-source dream. Dig just below, however, and an unsettling reality emerges: these aggregators are monetising the sweat, intellect, and creative risk of thousands, sometimes millions, of individual developers. The winds have changed. Your code—once a byword for progress—has become just another commodity, fuelling centralised profit with little return for its creators. This is the story of a digital gold rush where the diggers now find themselves locked out of the vault. Remember the wild dawn of open source, when so…  ( 9 min )
    Programming language of the future Part 3: OOP
    We want to manage state, by dividing it into units and giving them a name. Attaching behavior to them is also a good option - and thus we have OOP. But let's not adopt it blindly - a critical examination is in order. OOP is there to promote Encapsulation, Polymorphism, Abstraction. What would be the optimal way of providing them? Encapsulation means exposing only as much information about the object as necessary to provide the service. All of the information that is exposed and used by clients, if it were to be changed, means that either the client has to change at the same time - or versioning would need to take place. This idea makes sense, and for a language to support it, it would need ways to mark visibility of fields and methods. Polymorphism means for the same object to exhibit diff…  ( 5 min )

    Which Programming Languages Fuel Today’s Malware Attacks
    It is difficult to claim that any system or program is completely secure. All of them may contain potential vulnerabilities - errors made during the development process - that can lead to serious consequences. Attackers often exploit such flaws. Information security companies continuously monitor vulnerabilities and update security databases. Their monitoring typically includes sources such as the U.S. Government’s National Vulnerability Database (NVD), security advisories, GitHub issue trackers, and open-source projects. To create malicious code, attackers use a variety of programming languages. Some are more popular in cybercriminal circles due to their ease of use, compatibility with specific systems, and the wide availability of libraries that help solve particular problems.

    The Evolution of the Phrase “Click Here”: From Web Staple to Obsolete
    The phrase “Click here” was once a cornerstone of internet navigation. It was ubiquitous across websites, often used as a direct instruction to users: simply click a link, button, or piece of text, and something new would unfold—whether it was a download, a page redirect, or a pop-up. In the early days of the internet, this phrase was essential, helping users navigate a relatively new and confusing online landscape. But today, “Click here” is seen as a relic, a remnant of simpler times that no longer meets the standards of modern web design and user expectations. In this article, we will examine how “Click here” came to prominence, why it has lost its relevance, and the evolution of web design that has led to the adoption of more sophisticated, user-centered alternatives.

    Concurrency in Go
    ❓ What is Concurrency? Concurrency is the ability of a program to manage multiple tasks at once. These tasks may not run exactly at the same time, but they are managed in such a way that it feels like they are happening simultaneously. Imagine you’re cooking dinner: You put water on the stove to boil. While the water heats up, you chop vegetables. Once it’s boiling, you add pasta. While pasta cooks, you prepare the sauce. You are switching between tasks. You're not doing everything at once, but you're switching between tasks efficiently to save time. That’s concurrency: smart multitasking, not true parallelism (which involves tasks running at the exact same time on multiple CPU cores) In Go, concurrency means: Your program runs multiple tasks (functions or processes).

    What is UDP? Understanding the “Unreliable” Transport Protocol
    When you send a message over the internet—whether it’s a cat meme, a video stream, or a DNS lookup—it’s traveling through layers of protocols. Two of the most important transport-layer protocols in this stack are TCP and UDP. While TCP gets a lot of the spotlight thanks to its reliability and widespread use in web traffic, UDP (User Datagram Protocol) is the unsung hero behind many real-time and low-latency applications. In this post, we’ll demystify what UDP is, how it works, and why developers choose it despite its nickname: the "Unreliable Datagram Protocol." UDP is one of the core protocols of the Internet Protocol (IP) suite. It was introduced in 1980 as a lightweight alternative to TCP. UDP operates on top of IP and is used to send short messages called datagrams. The key difference?…  ( 4 min )

    前两天的文章内容对uniapp开发鸿蒙应用做了一些详细的介绍,包括配置开发环境和项目结构目录解读,今天我们正式开始写代码。 入门新的开发语言往往从Hello World开始,Uniapp的初始化项目中已经写好了一个简单的demo,这里就不再赘述,我们直接从布局开始说起。 Uniapp的布局方式和鸿蒙原生语言ArkTs有所不同,但又颇为神似。 幽蓝君之前总结过,所有的布局方式无非只有三种,横向、竖向和层叠,其他所有的布局方式都由这三种衍生而来,Uniapp也不例外。 ArkTs中有Row()、Column()、Stack()、Flex()这几个基础的布局容器组件,更复杂一些的还有像List()、Grid()、Scroll()等等。 而在Uniapp中,基础的布局方式我们通常直接使用view容器来实现。比如我想要实现一个横向的布局,使用view容器,在view的样式中设置布局方式为row: 而到了纵向布局,只需要把布局方向设置column就行了: 接下来比较难的部分到了,对于层叠布局,ArkTs直接提供了Stack()容器,并且有对应的对齐方式可以直接设置,比较简单。但是uniapp并没有提供这种对齐方式,flex-direction中是不能直接设置层叠布局的。 我们可以使用postion属性来实现。postion的作用是设置定位方式,有static、relative、fixed、absolute集中方式,我们今天要说的是absolute。 absolute是一种绝对定位方式,是脱离了文档流、相对于父元素的绝对定位方式。 更详细一点解释就是不管它有多少同级别的组件,都不影响它以父元素左上角为原点的定位,同样的它也不影响别人,相当于悬浮在上层,使用偏移量来控制位置。比如下面这段代码: 所以如果需要层叠布局的两个容器都使用absolute定位,并且使用top、left、bottom、right来设置对齐方式,就实现了鸿蒙中的Stack()一样的功能: 这里可以使用z-index来设置谁在上一层,另外,绝对定位的父容器需要设置position: relative属性,否则子组件无法找到目标。 以上就是Uniapp开发鸿蒙的基础布局方式,感谢您的阅读。  ( 3 min )
    Why I Built HubbleQuiz — A 10-Minute “Debugger” for Your
    Last year I found myself in yet another 1:1 with my mentor, staring at a blank calendar and wondering why my career wasn’t moving as fast as my code. He asked two simple questions: Which skill are you most confident about? Which skill scares you the most? I realized that, although I could spot a nasty bug in seconds, I had no systematic way to uncover my own blind spots or map out my next growth step. A quick dive into the 2024 Stack Overflow Developer Survey confirmed I wasn’t alone: Only 20% of developers report being truly happy in their roles 48% describe themselves as “complacent” 32% admit they’re actively unhappy That data drove me to sketch a simple 10-minute quiz on a napkin: 40 targeted questions to unearth your personal blockers Instant snapshot of your strengths & weakne…  ( 4 min )
    How to Implement a Custom WeighedBlockingCollection in C#
    Introduction to BlockingCollection and Memory Management In C#, the BlockingCollection class is a powerful tool for handling producer/consumer scenarios in a thread-safe way. However, when dealing with large objects that can vary in size significantly—like the ones you mentioned ranging from 10 MB to 700 MB—it's crucial to manage memory effectively to avoid OutOfMemoryExceptions. To achieve this, we need a customized collection that extends the functionality of BlockingCollection by allowing us to limit the total memory used by the items stored in it. Understanding the WeighedBlockingCollection The goal here is to create a custom collection called WeighedBlockingCollection, which will not only mimic the behavior of BlockingCollection but also impose a weight restriction on the …  ( 5 min )

    Mastering TypeScript: Union Types & Type Aliases Explained
    TypeScript offers powerful tools that help you write clean, scalable, and type-safe code. Two of the most useful features in this toolkit are Union Types and Type Aliases. In my latest YouTube video, I break down how to use these features effectively—even if you're just getting started with TypeScript. ✅ What You'll Learn ✅ What is a Union Type in TypeScript? ✅ How to use Union Types with function parameters ✅ What is a Type Alias and how to use it ✅ How to combine Union Types and Aliases ✅ Real-world use cases and code walkthroughs ✅ Common mistakes to avoid If you've ever found yourself repeating types or making your code harder to read, Union Types let you define a variable that accepts multiple types: let id: string | number; Meanwhile, Type Aliases allow you to give a custom name to a type: type ID = string | number; function printId(id: ID) { console.log("Your ID is:", id); } Combined, they make your code more readable, reusable, and easier to maintain. type SuccessResponse = { status: "success"; data: string; }; type ErrorResponse = { status: "error"; error: string; }; type APIResponse = SuccessResponse | ErrorResponse; function handleResponse(res: APIResponse) { if (res.status === "success") { console.log(res.data); } else { console.error(res.error); } } This is a clean, scalable way to handle multiple response types from an API. I walk you through all this and more in the full tutorial on YouTube: 👉 Watch on YouTube Whether you're building a small project or working with a large team, learning how to use Union Types and Type Aliases will make your TypeScript code more maintainable and developer-friendly.

    My Second Month as an LFX Mentee: Advancing Microcks Deployments
    Hello everyone! It’s been another productive month in the LFX Mentorship program with the CNCF Microcks project. This month, I focused on enhancing Microcks deployments on Google Kubernetes Engine (GKE) and improving documentation for cloud-specific deployment strategies. Additionally, I had the opportunity to present my contributions during the community meeting, where I encouraged others to contribute, provide feedback, and review the documentation. Asynchronous Options on GKE I worked on improving the Microcks GKE deployment by adding support for asynchronous protocols and securing the Microcks endpoint with TLS. Enabled Kafka-based async protocols with Helm and installed Strimzi for Kafka management. Secured the endpoint using cert-manager and Let's Encrypt for automatic SSL certificate provisioning. Deploying complex systems like Microcks with external Keycloak and MongoDB can sometimes lead to roadblocks. To address this, I created a TROUBLESHOOTING.md file in the repository. This document provides a set of common issues and solutions that developers may encounter when deploying Microcks on GKE, especially when integrating with Keycloak for authentication and MongoDB for data storage. Troubleshooting Guide I developed a GUIDELINES.md document that outlines the deployment process for Microcks across multiple cloud providers. The guidelines cover setting up infrastructure, deploying Keycloak, provisioning databases, and configuring Microcks with Helm. Common Guidelines Next month, I plan to: Deploy Microcks on Azure AKS and document the process. Add a Troubleshooting Guide for Azure deployment. Month two has been an exciting journey, contributing to Microcks with improvements in deployment, security, and cloud-specific guidelines. I’m excited to continue supporting the Microcks community and look forward to the next steps! Feel free to check out my contributions on the Microcks community repository  -  feedback and contributions are always welcome! See you in the next update! 👋  ( 3 min )

    Understanding JSON in JavaScript: A Complete Guide
    JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write and easy for machines to parse and generate. It's one of the most widely used formats in web development, especially when working with APIs and server responses. JSON is a text-based format for representing structured data. It resembles JavaScript object syntax, but it's a string. Example JSON: { "name": "Alice", "age": 25, "isStudent": false, "skills": ["HTML", "CSS", "JavaScript"] } They look similar, but they are different: Feature JavaScript Object JSON Data Type Object String Can contain functions Yes No Comments Allowed Not allowed Quotes on keys Optional Mandatory JSON.stringify() Converts a JavaScript object into a JSON string. const user = { name: "Bob", age: 30 }; const jsonString = JSON.stringify(user); console.log(jsonString); // '{"name":"Bob","age":30}' JSON.parse() Converts a JSON string back into a JavaScript object. const jsonString = '{"name":"Bob","age":30}'; const user = JSON.parse(jsonString); console.log(user.name); // 'Bob' fetch('https://api.example.com/data') .then(response => response.json()) .then(data => { console.log(data); // Parsed JSON object }); Most APIs return JSON. Using .json() parses the response body into a JavaScript object. Forgetting to wrap keys in quotes in JSON: { name: "John" } // Invalid Correct: { "name": "John" } Using functions in JSON: JSON.stringify({ sayHi: () => "Hi" }); // sayHi will be removed JSON is used for storing and exchanging data. Use JSON.stringify() to convert objects to strings. Use JSON.parse() to convert strings to objects. It’s widely used in API communication.

    How to Achieve a Parallax Effect on Mobile Browsers?
    Introduction to Parallax Scrolling Parallax scrolling is a web design technique that creates an illusion of depth by having background images move at a different speed than foreground content. This effect can make websites more visually engaging. However, achieving the parallax effect on mobile devices often presents challenges due to differences in how mobile browsers render scrolling and background images compared to desktop environments. Why Parallax Doesn't Work on Mobile Mobile devices handle scrolling differently than desktop browsers. The primary issue with your code appears to be linked to the way the CSS "background-attachment" property is rendered. This property often doesn't function as intended on mobile browsers, particularly when it comes to fixed backgrounds. As a result, ev…  ( 4 min )

    Crafting Minimal Viable IAM Permissions for Amazon Bedrock
    In many ways, most AWS accounts usually require very specific minimum viable permissions (MVP) assigned to user groups. This is usually controlled through templates like AWS Organizations Landing Zone, where the account governor usually has to manually define the scope of access manually. What if we could generate permissions policies via a prompt? As Cloud Governance specialist, we now have access to powerful tools like Amazon Bedrock and Langchain. But with great power comes great responsibility, especially when it comes to security. In this post, we'll explore how to create minimal viable IAM (Identity and Access Management) permissions for Amazon Bedrock when using it with Langchain, and we'll include some Python code examples.

    What Does {sys.executable} -m Mean in Python Code?
    In the realm of Python programming, you may encounter different methods to install libraries, particularly when using Jupyter Notebooks. A common practice involves the command !{sys.executable} -m pip install --user. This article will clarify the purpose of {sys.executable}, the -m flag, and the --user option, allowing you to better understand their utility. Understanding {sys.executable} The term {sys.executable} is a reference to the Python interpreter you are currently using.

    Microsoft and OpenAI renegotiate investment deal: Report
    Tech company Microsoft and artificial intelligence firm OpenAI are reportedly in talks to renegotiate the investment deal between the AI firm and Microsoft, which is OpenAI's biggest financial backer. According to a report from the Financial Times, Microsoft may give up a portion of its equity in OpenAI for continued access to the AI company's products and models beyond 2030, when some of the original terms of a deal signed between the two companies expire.

    Key takeaways: Ether has rebounded from key parabolic and triangle support levels, reviving the case for a $10,000 breakout.

    AI agents are coming for DeFi — Wallets are the weakest link
    Opinion by: Sean Li, co-founder of Magic Labs Crypto markets run 24/7. Human traders don’t. As AI agents begin to manage liquidity, optimize yield, and execute trades at all hours, they’re quickly becoming essential infrastructure for decentralized finance’s (DeFi) future. While AI agents are evolving from niche tools for quant traders into mainstream financial operators, they’re rapidly outpacing the wallets meant to secure them.  Advancements in account abstraction and smart contract wallets have emerged, but most DeFi platforms still predominately rely on externally owned account wallets that require manual approvals at every step. Early-stage programmable solutions exist but remain fragmented, costly on layer-1 networks and adopted by only a tiny fraction of users. As AI agents increas…

    Pectra lets hackers drain wallets with just an offchain signature
    Ethereum’s latest network upgrade, Pectra, introduced powerful new features aimed at improving scalability and smart account functionality — but it also opened a dangerous new attack vector that could allow hackers to drain funds from user wallets using only an offchain signature. Under the Pectra upgrade, which went live on May 7 at epoch 364032, attackers can exploit a new transaction type to take control of externally owned accounts (EOAs) without requiring the user to sign an onchain transaction. Arda Usman, a Solidity smart contract auditor, confirmed to Cointelegraph that “it becomes possible for an attacker to drain an EOA’s funds using only an offchain signed message (no direct onchain transaction signed by the user).” At the center of the risk is EIP-7702, a core component of the …

    Altseason is coming, 40% daily gains to become ‘new normal’ — Analyst
    Altcoin markets are flashing early signs of a breakout, with several analysts calling for a potential surge over the next few months. Crypto commentator Mister Crypto predicts the next 3 to 6 months could be “life-changing,” suggesting daily gains of up to 40% may soon become the norm. In a May 11 post on X, he pointed to a chart from BlockchainCenter.net that shows whether the crypto market favors Bitcoin (BTC) or altcoins. When the index is below 25, it’s considered “Bitcoin Season,” meaning Bitcoin is outperforming most altcoins. When it’s above 75, it’s “Altcoin Season,” meaning altcoins are doing better than Bitcoin. Currently, the chart shows a breakout from a downward trend just below the 29 mark, suggesting a possible shift away from Bitcoin dominance. This breakout hints that altc…
    Coinbase considered Saylor-like Bitcoin strategy before opting out: Bloomberg
    Coinbase CEO Brian Armstrong said his company had considered adopting a Bitcoin investment playbook like Michael Saylor’s Strategy on multiple occasions, but decided against it each time out of fear that it would kill the firm’s crypto exchange, Bloomberg reported. “There were definitely moments over the last 12 years where we thought, man, should we put 80% of our balance sheet into crypto — into Bitcoin specifically,” Armstrong revealed to Bloomberg in a May 9 video call. Armstrong said the Bitcoin (BTC) strategy could have risked the company’s cash position and potentially killed the crypto exchange. “We made a conscious choice about risk,” he added. Coinbase Chief Financial Officer Alesia Haas, who also attended the video call, added that the firm didn’t want to be seen as directly com…

    Declarative FullStack: Shifting Backend Ownership to the Frontend
    Abstract Introduction The conventional model of web application development separates frontend and backend responsibilities into different teams, skillsets, and codebases. Frontend developers manage UI and client-side logic, while backend developers handle server-side processing, API creation, data storage, and security enforcement. However, this division can lead to longer development cycles, coordination challenges, and duplicated logic across layers. A new paradigm is emerging—one in which frontend developers can declaratively define backend logic using frontend tools and syntax. This shift is enabled by modern platforms that offer serverless scalability, secure permission management, and efficient request/response handling under the hood. This approach doesn't eliminate the need for ba…  ( 5 min )
    What is the Difference Between UDF and Vector UDF in Spark 3?

    How to Manage Departments and Users in C# EF Core
    Introduction When working with Entity Framework Core (EF Core) in C#, managing relationships between entities is crucial. In this scenario, we have a case where a department can have multiple users, and when a user is assigned a new department, we need to ensure the previous department is deleted if it has no users left. This is a common requirement in applications that handle organizational structures. Why the Department Query Might Not Reflect Updates In your situation, you are attempting to update a user's department and then immediately check if the previous department has users left. You notice that even though the update reflects in the database, the department load returns stale data. This issue can arise due to EF Core’s change tracking behavior and how it interacts with the databa…  ( 5 min )
    How to Use Libuv In Your Zig Project
    Libuv describes itself as a multi-platform support library with a focus on asynchronous I/O. It is widely used in many web servers (e.g., Kestrel) and runtimes such as Node.js and Python (via uvloop). As of Zig 0.14.0, there is no native async I/O, so you must work directly with threads or create your own async API using OS primitives like epoll or kqueue. In many cases, you would likely choose a cross-platform library rather than implementing your own async API. That’s where using libuv, libevent, or libxev (written in Zig) becomes useful. This guide will show you how to use libuv from your Zig project. I’ll start with a basic Zig project to demonstrate how this works. It will be a simple app that runs some timers. We’re going to use the package from github.com/allyourcodebase/libuv to bu…  ( 5 min )

    Real-time Deepfakes: what if "seeing is believing" no longer means anything?
    An open-source project called Deep-Live-Cam is gaining traction on GitHub — and for good reason. With just a single still image, it can mimic anyone’s face in a live video call. In real-time. Running locally. No cloud required. The implication is clear: you can no longer trust a video call at face value. So here’s the question: how do we verify identity in a world where faces can be forged on demand? While many react with fear or disbelief, I see only one viable answer: digital signatures. For years, I’ve been saying: we should encrypt everything — files, messages, infrastructure. But now, that’s not enough. We need to start signing everything. Digital signatures ensure authenticity. They prove that something really came from who claims to have sent it and hasn’t been tampered with. We already sign emails, source code, and software packages. Why not apply the same principle to real-time streams? Imagine a video call cryptographically signed with the speaker’s GPG key. Even if the face looks convincing, if the signature doesn’t verify, you know something’s off. I sign every HTML page on my personal website with my GPG key. Not because I’m paranoid — but because I believe security should be a mindset. Don’t trust. Verify.  ( 3 min )
    How to Update a Progress Bar in MantineReactTable using WebSocket?

In this article, we'll explore how to effectively update a progress bar within a table using the MantineReactTable component in a React application. The focus is on integrating WebSockets to receive progress updates without causing unnecessary re-renders. Understanding the Challenge You might be facing an issue where your progress bar component does not rerender despite the state updates from useState. This can be confusing, especially when the console confirms that the state is updating. The problem often resides in how Reac's reconciliation process manages component updates and how state is propagated to child components.

    Solving "SDK 'Microsoft.NET.Sdk' Not Found" Error in Visual Studio
    If you're learning C# or .NET development, you might encounter this frustrating error: One or more errors were encountered while creating project ConsoleApp3. The generated project content may be incomplete. The SDK 'Microsoft.NET.Sdk' specified could not be found. I faced exactly this issue during my early days learning C#. After multiple attempts, I finally found a solution that worked reliably for me: The root cause appears to be that the official .NET SDK installer sometimes doesn't correctly set up the SDK on your system. Even after installation, the command dotnet --list-sdks might return an empty list, which indicates the SDK isn't properly recognized by your system. Here's what worked for me: Download the Binaries Manually: Go to the official .NET SDK downloads page. Instead of downloading the installer, choose the "Binaries" option. This will give you a .zip file containing the SDK files directly. Extract and Copy Files: Extract the downloaded .zip file to a temporary location. Replace SDK Contents: Navigate to: C:\Program Files (x86)\dotnet\ Delete or back up existing contents, then paste the newly extracted SDK binaries into this folder. Verify Installation: Open a new Command Prompt or PowerShell window and run: dotnet --info You should now see details about the SDK and runtime versions installed. This solution manually ensures that the SDK files are correctly placed and recognised by your system, bypassing the potential issues caused by the automated installer. If you're still experiencing issues after following these steps, consider checking your environment variables to ensure C:\Program Files (x86)\dotnet\ is correctly listed in your system PATH. I hope this guide helps anyone stuck with this annoying issue! If you find additional solutions or improvements, please share them—I'm still learning and would love to hear from you.  ( 3 min )

    How to Call gRPC Methods Dynamically in Go
    gRPC (Google Remote Procedure Call) is a high-performance, open-source framework for making remote procedure calls. Unlike traditional REST APIs that use HTTP/1.1 and JSON, gRPC leverages HTTP/2 and Protocol Buffers for more efficient communication between distributed systems. This modern approach offers significant advantages in terms of performance, type safety, and code generation capabilities. When working with gRPC, you need to understand the fundamental components and workflow that differentiate it from other API communication methods. The process begins with defining your service interface using Protocol Buffers (protobuf) in a proto file, which serves as a contract between client and server. This definition is then compiled into language-specific code that handles all the underlyin…  ( 5 min )

    Why does Bash not continue to the next iteration as expected?
    Introduction Have you ever faced an unexpected behavior in your Bash scripts, particularly regarding loops? In this article, we will delve into a common issue with the continue statement in Bash, as illustrated by your provided script. You're correct in observing that the continue statement should skip the remaining commands in the loop and jump to the next iteration. So, why isn’t it working as expected in your case? Understanding the Issue The primary reason the continue statement may not be functioning as you expected lies in the structure of your loop and the way Bash interprets commands. A common mistake is how command substitutions and pipes are handled in Bash scripts. When you use a pipe (|), the commands are run in separate subshells. This means the continue statement is scoped to…  ( 4 min )
    How Angular Schematics Help Developers Scale Architecture and Team Efficiency
    As software engineers, our job isn't just writing features or fixing bugs. We're responsible for improving the processes around software and help teams move faster, safer, and more consistently. That means asking questions like: Can we reduce repetitive tasks? Can we encode best practices so new team members don't guess? Can we lower the mental load of starting new features? For Angular projects, Schematics is one of the best tools to operationalize these improvements. It lets you automate architecture, encode standards, and enforce patterns. A schematic in Angular is a set of instructions that tells the Angular CLI how to generate or transform code. Think of it as a script that can: Create new files using templates.

    I Built an AI Platform That Lets You Create Your Digital Twin — Here's How It Works
    Hi devs — I recently launched a platform called aimodeling.me, and I’d love to share what it does, how it works, and why I built it. In short, it lets you create a realistic AI model of yourself — your own "digital twin" — from just a few selfies. After that, you can generate endless photorealistic images of you in any scenario, outfit, or setting you can describe. We’re all used to AI image generators now, but most of them produce generic faces or imaginary people. I thought: what if we flipped that? What if you could put yourself in those scenes? Professional photoshoots are expensive, awkward, and static. I wanted a way to generate high-quality, personalized photos for myself (for social media, bios, content creation, etc.) without constantly needing to step in front of a camera. So I b…  ( 4 min )

    209/365 | ¥10M Job Challenge - Tied Down in Japan
    Working in Japan under the constraints of a work visa means there’s really not much you can do besides your day job. About the only other option is saving money and investing through NISA... Even if your company allows side jobs, you still need to apply for “Permission to Engage in Activity Other Than That Permitted Under the Status of Residence,” and possibly register and communicate with the authorities. Just thinking about all that paperwork makes me not want to bother. After all, the main goal is to build a life where I can live long-term in a place I truly want to be — for me, that’s Japan. So in reality, my daily life basically revolves around working and studying to prepare for a career move. I won’t deny that this kind of routine gets a bit dull over time. I just want a little more freedom, especially since both language learning and job hunting take so much time. Anyway, I need to hit my goal as soon as possible so I can finally enjoy the freedom I want in Japan!  ( 3 min )

    Detecting Alzheimer's Disease with EEG and Deep Learning
    Abstract Alzheimer's disease (AD) represents a significant global health challenge. This paper proposes an experimental approach for early AD detection using Electroencephalography (EEG) signals processed through an innovative deep-learning architecture. I suggest a channel-frequency-based attention model that effectively captures spectral features across different brain regions. This model uses depthwise convolutions, squeeze-and-excitation blocks, and spatial dropout regularization to efficiently learn patterns within EEG data. The dataset has 19-channel EEG recordings from subjects with Alzheimer's, healthy controls, and frontotemporal dementia. The model shows 83.81% accuracy, which tells us about its potential.

    Simplify Your Cypress Intercept Assertions: cypress-intercept-search
    When writing end-to-end tests with Cypress, you must often validate that your application sends or receives the correct data. Cypress’s cy.intercept() gives you robust control over network requests. However, digging through nested bodies, headers, and query parameters to find the exact key/value you care about can become repetitive and error-prone. That’s why I created cypress-intercept-search, a small plugin that lets you recursively search through every part of one or more intercepted requests or responses for a given key and (optionally) a matching value. Then, wrap the results in a chainable Cypress command for easy assertions. ## Why Built cypress-intercept-search cy.wait('@savePlay').then((i) => { const { players } = i.request.body; expect(players).to.exist; Object.entries(play…  ( 4 min )
    How To Find the Right Tech Mentor in 2025
    Many years ago, I came across a profile on Twitter, now X, doing amazing things in development, and I was intrigued and wanted to get close to this person. I sent a couple of messages just to catch his attention, and when I asked him to be my mentor, he ghosted me. I felt so bad, like it hurt, but many years later, I understood. Because you feel he inspires you, it does not mean he/she is the right person to guide your growth. Mentorship has long been the cornerstone of personal and professional growth, especially in tech.

    How to Prevent an Image from Resizing in HTML?
    Introduction In web design, ensuring that images maintain their size when a user resizes their browser can be crucial. Many developers face challenges in retaining the original dimensions of images while still creating a responsive layout. If you've encountered similar frustrations—like trying to prevent an image from resizing, despite applying various styles—you're not alone. This guide will help you understand how to achieve this. Why Images Resize in a Responsive Layout Images typically resize in a responsive layout owing to CSS settings such as width, max-width, and other stylesheet rules. By default, images are treated as inline elements, and their sizing depends on the surrounding container. When modifying the browser window, the layout recalibrates, and unless the styles are explici…  ( 4 min )

    How to Reduce Duplication of Method Implementations in Go
    In Go, when you have multiple struct types that need to perform the same methods, it can often lead to code duplication. This issue is quite common, especially in cases where you have several struct types with similar methods. In this article, we will explore how to effectively reduce method duplication using interfaces and composition, thereby making your code cleaner and more maintainable. Understanding the Problem Let's begin by analyzing the problem you've presented. You have several structs (A, B, C, and D) that all implement the same methods, specifically Add and Remove. Repetition of code leads to maintenance challenges—any change in method logic must be mirrored across all structs, increasing the risk of errors.

    Guidelines for the first projects...
    This blog is for those, who want to start their first full stack development project but not have enough idea about how to start. I will try to cover some of the things that you should follow for make your first project journey more smooth. Folder Structure: The first thing you might face difficulties is creating and understand the folder structure. It may vary by project to project, but their are some common concept like creating 2 separate folder, one for frontend and other one is for backend. Inside each folder you will have multiple folders. For backend you will have folders like models, services, api endpoints etc (based on your requirements) . And for frontend, you will have src folder inside which you will find components, assets, pages, api, utils etc folders (if you are using React). fullstack-project/ Make sure you must write code as clean as possible. It is a good practice. You should right the logics more efficient way. You can also create a folder for a particular module and inside that you can create multiple files so that anyone can easily find the code written for a specific purpose. It will reduce cognitive complexity. Another thing you should remember that don't make a function so large with so much logics in a single function, rather use multiple functions, each for a particular logic and use them in that function. Before writing any routes, you should always first do some floor planning like how this routes is going to use, how many times this routes will be called. It is completely necessary when you are going to deploying the project into the server. Because the more api needs to call from backend, the more it will take time to load and resulting the website slow. Wish a happy journey for your first project 😄 and share if you find this post helpful.  ( 4 min )

    Programming language of the future. Part 2: State management
    Most programmers will agree that state management is a pain (in the head). Which is why they shy away from it at every opportunity. Languages, functional or OOP, make no difference - if state is only ever passed around to and from the database, it's all practically stateless in my book. In the industry-accepted programming model (clean model, layered model, hexagonal model) state management (database I/O) is on the outer layer - why? Oh, because you don't actually operate on entities that you store, you operate on transient entities derived from them. This abstraction is necessary, because in most modern languages state is carried by objects - and you can't store objects, only things derived from them. Be it rows in tables, or at least whole aggregates in NoSQL DBs. Actual object state can…  ( 4 min )

    Building true distributed systems with RoadRunner and Laravel
    I've been developing PHP applications for over 15 years now, working with various PHP frameworks. Throughout this journey, I've witnessed many projects that began as monoliths eventually need to evolve into microservices. That's when interesting architectural challenges emerge. While I'd successfully used RoadRunner (RR) with Spiral and Symfony before, I wanted to bring these same capabilities to my Laravel projects. Yes, Laravel Octane does provide RR integration but only for HTTP. I needed the full ecosystem of plugins that make RR truly powerful for distributed systems. If you're looking to build microservices where components communicate using gRPC, implement durable workflows with Temporal, or integrate your application with services written in other languages, you may have encountere…  ( 12 min )

    🔐 Stop hardcoding secrets: generate `.env` files from AWS SSM with a simple CLI
    At M47 Labs, we work on many AI and cloud-native projects where secret management becomes complex — especially across environments and CI/CD pipelines. We're big fans of AWS SSM for storing configuration and secrets securely, but syncing them into .env files can be painful and repetitive. To solve this in a cleaner and more reliable way, I built a CLI tool: 👉 Envilder on GitHub Envilder reads a mapping file that links environment variable names to AWS SSM parameter paths. .env file. Your param-map.json might look like this: { "DB_HOST": "/my-app/dev/DB_HOST", "DB_PASSWORD": "/my-app/dev/DB_PASSWORD" } Run: envilder --map=param-map.json --envfile=.env And you get: DB_HOST=mydb.cluster-xyz.rds.amazonaws.com DB_PASSWORD=supersecret You can also use different AWS CLI profiles: AWS_PROFILE=staging envilder --map=param-map.json --envfile=.env This small tool makes a big difference when: 🧑‍💻 Onboarding new team members: no more “what’s the DB password?” 🔄 Keeping environments in sync: any change in SSM is reflected across the team ⚙️ CI/CD pipelines always up-to-date: e.g. GitHub Actions, CodeBuild, GitLab 🧼 Centralized configuration: avoid duplication and keep secrets in one secure place 🧭 Supports multiple AWS profiles: ideal for multi-account or multi-env setups Works with SecureString and plain parameters CLI-first, fast, and script-friendly Compatible with any CI system Supports static values and fallbacks AWS profile support (AWS_PROFILE) npm install -g envilder Or: envilder --map=param-map.json --envfile=.env --profile=aws-account It’s still an early-stage project, but already helpful in several real-world teams. If this sounds familiar, or you’ve solved this differently, I’d love to hear from you. GitHub: https://github.com/macalbert/envilder  ( 4 min )

    Truthy and Falsy in JS: What Every Developer Should Know
    Stop Guessing: Understand JavaScript Equality the Right Way When you start working with JavaScript, one of the first things you notice is how flexible it feels. You can assign different types of values to the same variable and JavaScript won’t complain. This flexibility is great—but it can also lead to unexpected bugs, especially when you're comparing values or checking if something is "true" or "false." Let’s break down some of these concepts in a beginner-friendly way so you can write safer and more predictable JavaScript code. In JavaScript, you don’t need to declare the type of a variable. For example: let x = 5; // x is a number x = "hello"; // now x is a string x = true; // now x is a boolean This is called loose typing—a variable can hold any type of data, and JavaS…  ( 6 min )

    Amazon Q CLI for Code Review: Focus on What Changed, Not Everything
    This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line Some AI-powered coding assistants already support code reviews, but most of them tend to review an entire workspace or just the currently open file. In real-world scenarios though, code reviews are often based on pull requests—where we only need to review changes between two branches, not the whole project. For example, reviewing just the differences between a hotfix branch and main. That got me thinking: wouldn’t it be great if an AI coding assistant could handle that kind of focused review? At least as a first layer—giving us a detailed AI-generated review of the changes before we jump in manually. That way, human reviewers can just focus on refining things further instead of starting from scratch. One of Amazon Q Developer’s cool features is its CLI and MCP (Model Context Protocol) support. So I thought: why not use Amazon Q CLI to compare two branches—say, hotfix and main—and then have it go through the changed files one by one, review them, and finally compile the feedback into a single file using MCP as well? That way, whoever’s reviewing the PR can read the AI’s review first before doing their manual checks. Code Repository Code Review with Amazon Q Developer CLI I used Amazon Q Developer as the first layer of code review—comparing one branch to another, like from hotfix to main. This helps make the review process smoother, more effective, and scalable—especially when combined with a follow-up manual review. What makes it even more exciting is that Amazon Q Developer can both generate code and review it too. Pretty handy, right?  ( 4 min )
    Using Loose Equality in JS/TS
    -- Loose Equality allows different kinds to become an equal kind. I've been feeling, blogposts treat loose equality in JavaScript as a kind of black magic because people do not master it. It isn't supposed to be esoteric magic. I am not involved in browser development but I conducted my tests with Firefox and Chrome and I read the MDN pages. You can check the examples. I say, make full potential of Javascript's capabilities, intentionally and knowingly. It can save us from some coding overhead, even when the original definition is sometimes flawed. The loose equality can make code more concise… This means, if you know the types of the operands. Therefore, the loose equality is particularly useful with TypeScript, because it can show you the types of expressions. True, even TypeScript lack…  ( 8 min )
    Deploying and Exposing Go Apps with Kubernetes Ingress, Part 2

    Trying to Build in Public — But Reddit Keeps Silencing Me
    So this week, I tried to share what I’m building on Reddit. Two posts. Two different subreddits. Both were removed instantly by Reddit’s filters. No explanation. No mod feedback. Just gone. What were the posts about? I’m building a solo project called KindredCircl — a social platform focused on belonging, privacy, and connection. No ads. No rage-bait. No surveillance. Both posts were written thoughtfully. No spam. No “buy this.” Just honesty, tech stack, and a link to a longer write-up on Dev.to. But apparently, Reddit’s automation saw all that and said: nope. Reddit is supposed to be where indie hackers hang out. Where devs build in public. Where creators share early work and get support. But what I’m realizing is: if your post doesn’t match the format the filter expects, or if you use certain words (like support, link, or solo founder), you might just get silenced. Not because of what you said — but because a bot decided you were promotional by default. I’m still building. I’m still sharing. But I’m reminded how important it is to build spaces where authentic effort isn’t treated like spam. KindredCircl is meant to be one of those spaces. And yes — it still exists, even if Reddit didn’t want to hear about it this week. If you’ve had posts removed without explanation, or felt like you’re shouting into the void, I’d love to hear your story too. Let’s be loud for each other — since these platforms clearly won’t do it for us.  ( 3 min )
    Audio Steganography, Faster and Friendlier: My Dive into Spectrogram
    A few days ago, I stumbled across an interesting blog post by Solusipse about hiding images in sound—more specifically, encoding them into the spectrogram of an audio file. It reminded me of old-school tech like dial-up modems and the ZX Spectrum, but with a modern twist. Naturally, I had to try it. Solusipse provides a Python script, spectrology.py, that takes an image and converts it into an audio waveform whose spectrogram visually resembles the image. I cloned the repo, followed the README, and ran the script, hoping for a cool output. But things weren’t so smooth. The script hit an error out of the gate.

    Monotone Triangulation. Practical Advice.
    It all started innocently enough. Back in 2009, I just wanted to port Earcut to Flash for a mini-game I was working on. And honestly? It worked — for a while. But over time, I realized that simple solutions tend to fall apart the moment you try to push them to their limits. That’s when I dove into the theory - digging through research papers, YouTube tutorials, and whatever else I could find. One of the most helpful resources was a book by A.V. Skvortsov. Eventually, I landed on the classic approach: decomposing a polygon into monotone pieces. It seemed obvious. And oh - I hit every possible wall while trying to make it work. The first big insight? Replace float with int. That alone got me almost there. But the algorithm was still fragile. Really fragile. Self-intersections, collinear edge…  ( 7 min )
    The only 7 Projects That Makes You Better at Docker
    Docker isn’t just about running containers. It’s about understanding how systems work, why things break, and what to do next. Most tutorials give you commands to copy paste. This guide gives you projects to learn from, backed by theory and real-world context. By the end, I’ll share a secret most Docker experts won’t tell you a way to master it faster. Let’s start. Build a Multi-Container App with Docker Compose Modern apps rely on multiple services (like a web server, API, and database). Docker Compose orchestrates these services, handling networking and dependencies. Without it, you’d manually start each container and connect them a recipe for errors.

    Local PDF Parsing with AWS Textract & Python (Part 1)
    ✍️ Introduction Throughout my experience working with clients from domains like healthcare, insurance, and legal, I often found myself curious about how certain backend document workflows functioned, especially in healthcare. While supporting these systems, I’d often get paged for incidents related to PDF pipelines: upload failures, script errors, or extraction gaps. At that stage, like many in support roles, we’re limited to handling outcomes rather than building or understanding the full solution. Over time, as we gain more experience, build trust, and make people feel confident in our abilities, we gradually get the opportunity to be part of architecture discussions and solution design conversations. But that curiosity about how these pipelines actually work — from PDF upload to raw t…  ( 5 min )

    Why You Should Care About the Agent2Agent (A2A) Protocol as a Developer
    AI agents are no longer science fiction. We're moving fast toward a world where intelligent agents assist in everything from customer service and infrastructure orchestration to dev workflows and automated research. These agents aren’t monoliths—they're modular, specialized, and increasingly autonomous. But there’s a problem: Each one is often trapped in its own framework or API, with no standardized way to talk to others. That lack of interoperability is a major blocker to scaling truly useful, distributed AI systems. That’s where the Agent2Agent Protocol (A2A) steps in—and if you're a developer, now is the time to start paying attention. 🧠 What Is the A2A Protocol?

    A constructor function is a special type of function used to create and initialize objects in programming, particularly in object-oriented languages like JavaScript. Think of it as a blueprint or factory for making many similar objects. Imagine you're managing a car manufacturing company. Every car you build shares the same structure—engine, wheels, color, and brand—but each one has its own values. Instead of manually building each car from scratch, you use a car-making machine (constructor function). You input values like color, brand, and engine size, and the machine builds the car for you. function Car(brand, color, engineSize) { this.brand = brand; this.color = color; this.engineSize = engineSize; } This is the constructor function.

Lightweight and flexible, it's not going unrecognized by the low-level developers with its focus on manual memory management, compile-time safety, and minimal run-time overhead. With this adoption trend, that question arises among many of how true this is: ''Is Zig a real competitor to Rust?'' Hence, in the following article, we shall compare Rust and Zig, note significant differences, and possibly help you decide on which of the two you are planning to learn in 2025. Why is Rust So Popular? 1. Memory Safety Without a Garbage Collector 2. Fearless Concurrency 3. Performance on a Par With C and C++ Rust provides zero-cost abstractions that allow a high level of expressiveness in writing programs while incurring little or no run-time overhead. In many cases, Rust is as fast as or faster than C/C++. 4. A Thriving Ecosystem and Strong Tooling Rust Uses and Applications For massively scalable applications, Rust fits the bill. The flip side of such scalability would certainly be a lot of complexity, and this is where Zig fills the void. The Minimalist Challenger: Zig Unlike Rust's expensive and stringent powers with sections for systems programming, Zig is strictly minimalist and performance-optimized with no specific automated memory management.

    Two Worlds, One Goal: Creating Balance.
    Now this... this is where the real battle began. On one side, Blockchain Development — a world of code, decentralization, and smart contracts. Forex Trading — candles, charts, patterns, and pips. So where do I go from here? At first, it was chaos. I’d be deep in writing a smart contract in Solidity, then moments later, I’d find myself back on TradingView, analyzing XAU/USD like my life depended on it. My mind was constantly bouncing between gas fees and candlesticks. I knew something had to give — this back-and-forth was draining my focus, and if I kept going like that, I’d end up mastering neither. So I paused. “How do I fix this?” After some much-needed clarity, I narrowed it down to three options: Quit trading and go all-in on tech. Quit tech and go all-in on trading.

    Question: Design changes in my Next.js + Tailwind app do not reflect in production (Vercel)
    I’m building a project using Next.js (latest version) with Tailwind CSS and deploying it to Vercel. The issue is: all design changes (layout structure, visual style updates, etc.) show up perfectly in local development, but they don’t appear at all on the production URL after deployment. Things I’ve tried: git push to main runs without errors. Vercel deployment shows status as “Ready” with no build errors. Forced browser refresh (Ctrl+Shift+R), cleared cache, used incognito mode. Tested on multiple browsers and devices. What could prevent design changes from being reflected in production? I’d appreciate any advice or suggestions. I’ve repeated the steps multiple times and still can’t get the updated design to show live.  ( 3 min )

    JSON (JavaScript Object Notation): The Universal Data Exchange Language
    In the digital age where apps talk to servers, systems talk to each other, and devices sync data across continents, JSON stands tall as the standard language of communication. Simple in form but powerful in function, JSON is a foundational technology in software development, used across web, mobile, IoT, AI, databases, and cloud platforms. Let’s break down JSON from theory to real-world practice, with examples and project-level applications. JSON (JavaScript Object Notation) is a lightweight text-based format for representing structured data. Despite its name, JSON is language-agnostic, and supported natively or via libraries in virtually all programming languages.

    Cloud Service Types: IaaS, PaaS, SaaS
    Cloud computing isn't simply a catchphrase in today's digitally first society; it's the foundation of contemporary company operations. The cloud makes speed, size, and cost-effectiveness possible for everyone from start-ups releasing mobile apps to multinational corporations overseeing operations worldwide. However, "the cloud" isn't a universally applicable answer. Different kinds of cloud services are available, depending on what you're building and how much control you desire. Let's dissect them. 1. Infrastructure as a Service (IaaS) What User Manages: What the Provider Manages: Use Cases: Examples: Ideal for: Developers and system administrators who want flexibility without managing hardware. 2. Platform as a Service (PaaS): What User Manages: What the Provider Manages: Use Cases: Examples: Ideal for: Developers who want to build applications quickly without worrying about backend setup. 3. Software as a Service(SaaS): What User manages: What the Provider Manages: Use Cases: Examples: Ideal for: End-users or businesses who want to use powerful software without installing or maintaining it. What Should You Pick? Choose Infrastructure as a Service (IaaS) if you require total control over your environment. Select PaaS if you wish to concentrate just on development. SaaS is your friend if all you need to do is use an app to get started quickly.  ( 4 min )

    Why is the URL parameter None in FastAPI from Next.js?
    Understanding the Issue of Missing URL Parameter in FastAPI When using a Next.js frontend to send data to a FastAPI backend, it's important to ensure that all parameters, including files and URLs, are properly formatted and sent in the FormData. In your case, while the username and files are being received correctly by the FastAPI endpoint, the urls parameter is showing up as None, which can be quite perplexing. Let’s dive into the potential reasons why this is happening and how to resolve it. Reasons Why the URLs Parameter Might be None Incorrect FormData Structure: One common reason for receiving None in the FastAPI backend for the urls parameter could be due to the way the data is appended to the FormData in the Next.js code.

    Building Legal AI Tools: Challenges Developers Need to Know Before Writing a Single Line of Code
    Legal tech is booming, but building for the legal industry comes with hidden technical, ethical, and compliance challenges..here’s what every dev should understand before jumping in. So you want to build the next AI tool that revolutionizes law? Great!!legal professionals need better, faster tools. But before you start coding your first legal document parser or compliance bot, there are real-world landmines to avoid. Legal data is often highly sensitive and subject to strict confidentiality rules (think attorney–client privilege or court-sealed documents). Scraping, storing, or even training on this kind of data without safeguards could expose you and your users to legal risk. Also, when your AI outputs a compliance decision (e.g., GDPR audit findings or AML flags), you're not just providing a "suggestion", you may be influencing legal liability. Many jurisdictions require explainability, auditability, and even human-in-the-loop systems. Legal language is dense, full of nuance, and jurisdiction-dependent. Two identical phrases may have opposite meanings depending on where and how they appear. Of course, you know there are already APIs and frameworks built for legal applications. Don’t reinvent the wheel. Legal professionals are risk-averse by design. They value clarity, documentation, and accuracy over speed. Your app’s UX must reflect that. If they can’t trust it, they won’t use it, no matter how smart it is. Are you building legal tech tools? What challenges have you run into? Drop a comment or connect—let’s push the future of legal AI forward, together.  ( 3 min )

    uniapp开发HarmonyOS NEXT应用之项目结构详细解读
    昨天的文章介绍了使用uniapp跨平台鸿蒙应用时如何配置开发环境和运行调试项目,今天介绍一下uniapp项目目录的结构。 上面的两个文件夹pages中存放的是项目的页面,static则是存放静态资源的文件。 继续往下面看,App.vue文件打开可以看到它里面存放了项目的生命周期函数,比如项目启动、项目退出等等。 index.html相当于项目的根页面,它虽然也属于页面,但是在uniapp中通常是不需要大家修改的,因为可以看到里面有一个id是app的容器,我们在项目中写的所有代码最终都会注入到这个容器中。 Main.js是整个项目的核心入口文件,负责初始化Vue实例和全局配置 Manifest.json中存放了项目的各种配置文件,项目的名称、版本、描述、各个平台的的运行配置都在这里。 Pages.json中存放了项目中所有的页面路径和全局样式,尝试在globalStyle中的样式做一些修改,项目的全局样式就会被改变。而当新建了一个页面时,也会在这里自动注册。 最后的uni.scss文件,打开可以看到它已经给出了解释,这里是uni-app内置的常用样式变量。 以上就是uniapp项目初始化后的项目结构,还没结束,当我们运行项目后,还会新增unpackage目录,打开可以看一下是不是很熟悉,编译器把uniapp项目编译成了鸿蒙项目,这就是跨平台开发的运行原理。 以上就是对uniapp项目结构的详细解读。经历了两天的项目环境搭建和介绍,接下来的教程我们会进入到正式的跨平台开发编码环节,欢迎您持续关注。  ( 2 min )

    Project made with latest Angular 19 features
    I've embarked on a project that, although simple, has been a challenge. I've built my personal website, resume, and code visible on GitHub. This has been a bit of a challenge, because I knew my code would be visible and analyzed by recruiters. Still, I did it with love and enjoyed the experience. With it, I've had to be a software architect, content creator, project manager, developer, and SEO. Along the way, I've learned and grown. I've seen things I want to take to other projects, and the importance of following the principles of clean code, design patterns, and an architecture that's easy to scale. This project is built with Angular version 19. I use standalone components, computed properties, and effects, as well as rxResource and new features of the framework. For the UI, I used Angular Material, but minimally. The design is simple, designed so that people with visual impairments can use it without problems, balancing color contrast and good visual results. The result is my personal website, which I've been building little by little, and which I'm now sharing with you at www.antonioubedamontero.com. I'm making small improvements, adding features, and polishing what will become my brand image.

    How to Implement Instance Counters with Class-Level Variables in Ruby?
    Understanding Instance Counters in Ruby In the world of object-oriented programming in Ruby, ensuring that each class maintains its own instance counter is a common requirement. This article explores how to implement instance counters for classes in Ruby using class-level instance variables, as opposed to class variables which are shared among all subclasses. We will tackle the problem of accessing these counters while keeping their setters private, ensuring that they cannot be modified from outside the class hierarchy. Why Use Class-Level Instance Variables? Using class-level instance variables (like @instance_count) allows different layers of a class hierarchy to maintain their own counters. This avoids the pitfalls of class variables (denoted by @@), which are shared across all instance…  ( 4 min )

    Exploring Compile-Time Programming in Zig: Practical Examples and Use Cases
    One of Zig’s most powerful features is its ability to run code at compile time. This enables code generation, validation, and optimizations that would be much harder (or impossible) in many other languages. In this tutorial, we’ll walk through practical examples of Zig's compile-time programming and how you can use it effectively. You can run code at compile time using comptime: const std = @import("std"); const num = comptime calculate(); fn calculate() usize { std.debug.print("Evaluating at compile time\n", .{}); return 42; } Here, calculate() is run at compile time, and num becomes a constant value. comptime Parameters Zig lets you write generic functions and types using comptime parameters: fn identity(comptime T: type, value: T) T { return value; } const result = ide…  ( 4 min )

    How to Store Data in a Dart Class Using Maps Correctly?
    Introduction If you're new to Dart and want to manage data efficiently, using a class to store instances in a map is a great approach. In your case, you're trying to maintain a persistent map that holds instances of myCar, but you're encountering an issue where the map is reset every time addInfoToMap() is called. Let's explore why this is happening and how to fix it. Why is myMapOfCars Being Reinitialized? The main reason myMapOfCars is reinitialized each time is that it's defined as an instance variable (implicitly associated with each instance of the myCar class) rather than as a static variable that belongs to the class itself. Each time you create a new instance of myCar, a new myMapOfCars is created, which is why it appears empty when you call addInfoToMap(). Solution to Persist Data…  ( 4 min )

    A Beginner's Guide to Enums and Error Sets in Zig
    Enums and error sets in Zig offer powerful ways to model states and failures with clarity and precision. In this tutorial, we’ll cover the basics, then walk through real-world uses of both types — and how they play nicely together. Enums let you define a type with named values: const Direction = enum { North, South, East, West, }; You use them like this: const dir = Direction.North; Zig will guarantee at compile time that dir is one of the defined directions. Zig encourages exhaustive switching — the compiler checks for missing cases: switch (dir) { Direction.North => std.debug.print("Going up\n", .{}), Direction.South => std.debug.print("Going down\n", .{}), Direction.East => std.debug.print("Going right\n", .{}), Direction.West => std.debug.p…  ( 4 min )

    💍 aws-vault-lite: One AWS Secret to Rule Them All
    This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Exploring the Possibilities At my company, we still don’t have a proper tool to manage secrets. So, naturally, people come up with their own solutions—some of them not very secure. I had the idea of using AWS Secrets Manager as a secure place to store our secrets. But there was a challenge: Then I discovered that a single AWS Secret can store up to 64KB, which is more than enough for a bunch of simple strings. That got me thinking... So I did it! :) Introducing aws-vault-lite — a lightweight secret manager I built in just one night (with a hand from Amazon Q). What is? That was a pretty polite intro, wasn’t it? This what you could expect from the app. Try it at: https://github.com/fabiocore/aws-vault-lite I always…  ( 9 min )

    How to Resolve Discord Bot HTTP 403 Forbidden DM Issues?
    Introduction If you're developing a Discord bot using Go and experiencing the error HTTP 403 Forbidden when trying to send direct messages (DMs) to users, you're in the right place. This article will explore common reasons why your bot may not be able to send DMs and provide actionable steps to resolve the issue. Understanding the Error The error message you encountered: HTTP 403 Forbidden, {"message": "Cannot send messages to this user", "code": 50007} indicates that your bot is attempting to send a message to a user who has disabled DMs from server members. This is a common issue and can occur even if the bot is in the same server as the user. Why Can't My Bot Send DMs? In Discord, users have the ability to adjust their privacy settings. Here are a few reasons why your bot might be unabl…  ( 5 min )
    Mastering SQL Joins: Your Definitive Guide to Relational Data Mastery
    In the modern data-driven world, working with relational databases is inevitable for backend engineers, full-stack developers, and data analysts. And at the heart of relational data querying lies one foundational skill: SQL JOINs. If you’ve ever been confused by LEFT, RIGHT, INNER, and FULL OUTER JOIN, this article will clear it up once and for all—with examples, visuals, and real-life reasoning. Let’s get you from novice to JOIN Jedi. JOINs allow you to combine rows from two or more tables based on a related column between them. Think of them as building bridges between datasets. The four most commonly used JOINs in SQL are: INNER JOIN LEFT JOIN RIGHT JOIN FULL OUTER JOIN Each has its own behavior for matching and preserving data from the joined tables. Let’s imagine we have two tables: -…  ( 4 min )

    How to Fix the 'Terminate called after throwing an instance of char const*' Error in Qt?
    Introduction If you are working on a Qt application and encounter the error message "Terminate called after throwing an instance of 'char const*'", it's likely due to an issue in how you are handling strings, particularly when converting between different types. This guide will analyze your code and help you troubleshoot this problem effectively. Understanding the Error The error "Terminate called after throwing an instance of 'char const*'" typically means that your application has encountered an unexpected situation, leading to an exception being thrown.

    Text Adventures in the Age of AI
    I loved text adventures as a kid. Still do. I even wrote a few, though I never had the courage to show them to others. The DnD games I played with friends had a step-up on this, of course: a human being who could intelligently respond to anything you tried. It was only a matter of time before somebody had the idea to use AI for adventure games, and there are some interesting options out there I'm keen to try sometime: AI Dungeon, DREAMIO and Friends & Fables. Inworld Origins looks like it will take it even further and provides a cinematic experience where you talk to suspects at a crime scene, and they respond intelligently to anything you ask. The possibilities to this are staggering. But back to text adventures.. One day I was mucking around in Copilot, trying to find weird things to a…  ( 5 min )

    El Salvador stacks 7 Bitcoin in last week, despite IMF deal
    The government of El Salvador continues stacking Bitcoin (BTC) for its national crypto reserve, despite an ongoing deal with the International Monetary Fund (IMF) stipulating that the Central American country stop using public funds to purchase Bitcoin as one of the conditions for a loan agreement. According to data from the El Salvador Bitcoin Office, the country acquired an additional seven BTC in the last seven days, bringing its total holdings to 6,173 BTC, valued at over $637 million. El Salvador's Bitcoin Office has continued its steady pace of Bitcoin acquisitions months after the IMF agreement was signed and shows no sign of halting its Bitcoin purchases. The Central American country is one of the only nations actively purchasing Bitcoin in open market operations, and its national …
    Bitcoin SV investors attempt to resurrect 2019 Binance lawsuit
    Investors of Bitcoin Satoshi's Vision (BSV) — a hard fork of Bitcoin Cash (BCH), which itself is a hard fork of the Bitcoin (BTC) protocol, are attempting to revive a 2019 lawsuit against crypto exchange Binance for delisting the altcoin, which the litigants claim stunted the price of BSV.   According to Law360, attorneys for the plaintiffs argued that a July 2024 decision from the UK Competition Appeal Tribunal dismissing the "loss of chance" claim made against Binance for delisting the token, should be reconsidered. The litigants demanded $9 billion in damages, in the original case. The investors continue to claim that Binance's 2019 delisting of BSV and similar major exchange delistings are the primary drivers of BSV's long-term price decline and its failure to attract the investor atte…
    Bitcoin now deflationary due to Strategy's BTC purchases — Analyst
    Strategy, a Bitcoin (BTC) treasury company, is accumulating Bitcoin at a faster rate than total miner output, giving the supply-capped asset a -2.33% annual deflation rate, according to CryptoQuant CEO and market analyst Ki Young Ju. "Their 555,000 BTC is illiquid with no plans to sell," the analyst wrote in a May 10 X post. "Strategy's holdings alone mean a -2.23% annual deflation rate — likely higher with other stable institutional holders," Ju continued. Michael Saylor, the co-founder of Strategy, is an outspoken Bitcoin advocate who evangelizes the scarce digital currency to potential investors and has inspired many other companies to adopt a Bitcoin treasury plan. The total BTC supply is shrinking due to Strategy accumulating Bitcoin. Source: Ki Young Ju Additionally, Strategy acts as…
    In volatile markets, RWAs like gold are a lifeline
    Opinion by: Kevin Rusher, founder of RAAC It’s a volatile world out there. This year, we’ve seen stocks take a wild ride as gold has pumped and crypto has been caught somewhere in the middle. Investors have dumped risk assets and scrambled for safe havens. Gold is leading the charge. While gold is safe, it is not very hard-working. Unlike cash and treasuries, the yellow metal does not generate income. Now, more than ever, investors need to be able to earn yield on gold — particularly in the decentralized finance (DeFi) sector. The only way to make money from gold is to buy low and sell high. Most investors don’t tend to buy gold like this. That’s for good reason — over the long term, gold’s performance is typically consistent, if not without a few peaks and troughs here and there, as we h…
    Why is Ethereum (ETH) price up today?
    Key takeaways: Ether is set for its best weekly gain since May 2021. Ethereum’s Pectra upgrade, mega-whale accumulation, and a major short squeeze fuel the rally. Technical patterns suggest a potential 40% rally toward $3,400 as ETH bounces off key support. Ether (ETH) is on course to record its best weekly performance since May 2021, having risen by over 37.50% in the week ending May 11, including 10.30% gains in the last 24 hours. US tariff updates, Pectra upgrade boost Ethereum The announcement of a new trade agreement between the US and the UK on May 8 and the initiation of US-China trade talks afterward have bolstered upside sentiment in Ether and the broader crypto market. Additionally, Ether benefits from its Pectra upgrade on May 7, which introduced key improvements like higher…
    4chan rises from the dead: How the imageboard moves crypto markets
    After 4chan was hacked on April 14 and vast troves of user and moderator data were leaked online, the controversial website quickly went down, and many believed it would never recover. However, less than two weeks later, the imageboard was back online, defiant as ever. “4chan is back,” an official blog post proclaimed. “No other website can replace it, or this community. No matter how hard it is, we are not giving up.” The imageboard has left its mark on the world in many consequential ways, birthing countless memes and conspiracy theories, serving as a platform for political movements ranging from the alt-right to Anonymous, and acting as a dumping ground for leaks and hacks of all sorts.  Crypto is no exception, with 4chan also a historically influential gathering place to share altcoin …
    UK to become ‘safe harbor’ for crypto with new draft rules — Experts
    On April 29, UK Finance Minister Rachel Reeves unveiled plans for a “comprehensive regulatory regime” aimed at making the country a global leader in digital assets. Under the proposed rules, crypto exchanges, dealers, and agents will be regulated similarly to traditional financial firms, with requirements for transparency, consumer protection, and operational resilience, the UK Treasury said in a statement released following Reeves’ remarks. Per the statement, the Financial Services and Markets Act 2000 (Cryptoassets) Order 2025 introduces six new regulated activities, including crypto trading, custody, and staking. Rather than opting for a light-touch regime similar to the EU’s Markets in Crypto-Assets (MiCA), the UK is applying the full weight of securities regulation to crypto, accordin…
    RedotPay enters South Korea with crypto-powered payment cards
    Hong Kong-based fintech firm RedotPay has reportedly launched its cryptocurrency-enabled payment cards in South Korea, positioning itself as a potential disruptor in a market dominated by traditional credit card firms and mobile payment services. The company’s crypto debit cards—both physical and virtual—are now accepted at all Korean merchants that support Visa, according to a May 9 report by The Korea Economic Daily. The move marks RedotPay’s latest step in global expansion, following its earlier partnership with Visa and BIN sponsor StraitsX in February 2025 to enhance cross-border crypto payment capabilities. RedotPay, founded in 2023, has rapidly scaled since the soft launch of its crypto card program in late 2024. It now serves more than 4 million users worldwide. In South Korea, use…
    Robert Kiyosaki says ditch ‘fake money’ for Bitcoin, gold, and silver
    Robert Kiyosaki, businessman and best-selling author of Rich Dad Poor Dad, is once again sounding the alarm on the dangers of centralized monetary policy — urging his followers to abandon what he calls “fake money” and adopt alternatives like Bitcoin, gold, and silver. In a May 10 post on X, Kiyosaki backed a hardline stance against central banking systems, particularly the Federal Reserve, while quoting former US Congressman Ron Paul. Ron Paul, a longtime critic of the Fed and author of End the Fed, described interest rate setting by central banks as “price fixing,” equating it to socialist and Marxist economic control. Paul warned that such mechanisms erode personal wealth and undermine economic freedom — a sentiment that aligns closely with Kiyosaki’s long-held concerns. “Fake money lea…
    BlackRock’s Bitcoin ETF posts $356M inflows, longest inflow streak in 2025
    BlackRock’s spot Bitcoin ETF (IBIT) capped off the trading week with another day of inflows, pulling in $356.2 million on May 9. The fund has now extended its inflow streak to 19 consecutive days — its longest run of inflows so far this year. IBIT’s inflow streak has been ongoing since April 14, and has coincided with a volatile Bitcoin (BTC) market, with the asset trading between $83,152 and $103,000 over the period. However, market sentiment has been increasing after the asset reclaimed and held above the $90,000 price on April 23 before reclaiming the $100,000 price on May 8 for the first time since Feb. 1. Bitcoin ETFs ticking along as Bitcoin price spikes Over the past trading week alone, IBIT posted $1.03 billion in inflows, according to Farside data. Prior to the current 19-day stre…
    Bitcoin won’t see ‘gigantic’ SWF buying until laws greenlit — Scaramucci
    Sovereign Wealth Funds are already gaining exposure to Bitcoin, but significant allocations won’t happen until the United States establishes clearer regulations for the digital assets industry, says SkyBridge founder Anthony Scaramucci. “I think they are buying it, I think they are buying it on the margin,” Scaramucci, former White House director of communications during US President Donald Trump’s first term, said on Anthony Pompliano’s podcast on May 8. Legislation will lead to “large blocks of buying” “I don’t think it is going to be a gigantic groundswell of buying until we greenlight legislation in the United States,” he added. Scaramucci previously said in a February interview with the Financial Times that he expects the US government to propose crypto legislation in November. SWFs a…
    Bitcoin yet to hit $150K because outsiders are ghosting — Michael Saylor
    Strategy founder Michael Saylor says Bitcoin hasn’t reached $150,000 yet because holders without a long-term outlook have been selling off while a new cohort of investors are beginning to enter the market. “I think we’re going through a rotation right now,” Saylor said on the Coin Stories podcast with Natalie Brunell on May 9. The lack of “10-year investor mindset” led to Bitcoin sell-off Saylor said “lots of non-economically interested parties are rotating out of the asset.” However, at the same time, “a new cohort of investors are entering.” “A lot of Bitcoin, for whatever reason, was left in the hands of the governments and the hands of lawyers, and in the hands of bankruptcy trustees,” he added. Strategy’s Michael Saylor spoke to Natalie Brunell on the Coin Stories podcast. Source: Na…
    Ethereum price greenlit for further upside after surprise 29% ETH rally
    Key takeaways: ETH price rallied by 22% on May 8, but demand for spot ETH ETFs and derivatives remains muted.  President Trump’s reversal on certain altcoins aligns with ETH’s renewed outlook.  Ether (ETH) posted an impressive 29% gain between May 8 and May 9, likely marking the end of a 10-week bear market that bottomed out at $1,385 on April 9. This sharp move triggered the liquidation of over $400 million in short (sell) ETH futures positions, suggesting that whales and market makers were caught off guard. Despite the surge, traders have maintained a neutral stance in ETH derivatives. Whether this apparent lack of conviction reflects a genuine trend reversal or merely precedes another test of the $2,000 level remains to be seen. Ether 3-month futures annualized premium.

    A spread argument must either have a tuple type or be passed to a rest parameter. ts(2556)
    You want to pass variable args to a function, like so: const doSomething = (a: string, b?: string, c?: string): void => {}; However, TS didn't like it... // não bom const args = [['a', 'b', 'c'], ['a', 'b'], ['a']]; args.forEach((arg) => { // A spread argument must either // have a tuple type or be passed // to a rest parameter. ts(2556) vvvvvv doSomething(...arg); }) The problem is that doSomething expects one to three arguments of type string, but arg is typed as string[]. We need to narrow the type down, to match the arguments of doSomething() // bom const properTypedArgs: [a: string, b?: string, c?: string][] = [['a', 'b', 'c'], ['a', 'b'], ['a']]; properTypedArgs.forEach((arg) => { doSomething(...arg); }) This works, but if you don't fancy re-typing the function's argument type defs or don't have it handy, TS utility type got you covered: // ainda melhor const properTypedArgs: Parameters[] = [['a', 'b', 'c'], ['a', 'b'], ['a']]; properTypedArgs.forEach((arg) => { doSomething(...arg); }) That's all!

    Debugging Browser Extensions: Taming the Chaos Like a Pro 🛠️
    Hey fellow developer! 👋 Let’s talk about the real journey of building browser extensions: You spend hours crafting the perfect feature, hit "Load Unpacked," and… nothing happens. Or worse—your extension works on your machine but turns into a pumpkin 🎃 on your friend’s browser. Debugging extensions can feel like wrestling gremlins, but don’t panic! I’ve been there (and lived to tell the tale). Let’s break down the most common errors and their fixes so you can get back to shipping magic. 1. “My Extension Doesn’t Load!” (Manifest File Mayhem) The Error: Chrome/Firefox ignores your extension, or you get a cryptic “Invalid manifest” warning.

    Coding Challenge Practice - Question 5
    Today's question Create a React application that allows users to create, display and delete blog posts. Solution The first step is to evaluate the boilerplate provided. There are 3 boilerplate files: Home.js import React from "react"; import Input from "./Input"; import PostDisplay from "./PostDisplay"; function Home() { return ( {"Title"} {"Description"} Delete ); } export default PostDisplay; The Home component(file) is provided as the parent component, which manages the state of the application. So, variable states for all blog posts, and a single new blog post will be created. The input component is responsible for creating new blog posts, therefore, the variable states for new blogs will be passed into it after it has been created in the Home component. Then, the PostDisplay component, which handles showing all blog posts, will have the state for all blog posts passed into it.  ( 3 min )

    How to Fix Colorization Issues in Dart's Pathfinding App?
    Introduction Are you currently tackling a pathfinding visualizer app using Dart and Flutter? If you're feeling overwhelmed by the programming challenges and specifically by your container colorization logic, you're not alone! In this article, we will go through how to successfully manage color changes for your start and end containers without affecting all elements on the grid. Understanding the Problem In your Flutter application, the objective is to select a 'start' and 'end' container when clicking on the grid, and change their colors accordingly. However, when you try to set the 'start' container color to green, it’s inadvertently updating every container to green, which is not the intended behavior. This issue typically occurs due to how the state and rendering logic is structured in …  ( 4 min )

    Finding (and recovering) your Amazon Q Developer prompt history
    Wanted to share a very quick on something I learned that was pretty useful to me, so thought it might be useful to others. Here is a scenario that some of you might be familiar with: You have a successful Amazon Q Developer session, and then maybe a few days later, you are trying to recall exactly what you did and how you put your prompts together - what can you do? As it turns out, a recent update to Amazon Q Developer was a big help. In the Amazon Q Developer chat interface, there is a new icon next to the different tabs (its an icon of a click, which when you hover over says "View Chat History") which when you click on this, it will bring back a list of previous chats that have been recorded. What does this mean? In the "~/.aws/amazonq/" directory there is a "history" directory, and looking at it, it contains a number of time/date stamped json files. ├── history │   ├── chat-history-0f97086b54fd7d6128dfd80426dfd63d.json │   ├── chat-history-10d817f64fc99f04badf1568a6c23814.json │   ├── chat-history-deba93a681a17ae26ff2b977acf0ba97.json │   ├── chat-history-fa5091a7425e7938fe770a584b63076e.json │   └── chat-history-no-workspace.json These are what the Amazon Q Developer VSCode plugin now produces as you start using it. That said, because I had deleted my project, and so I was unable to get this from VSCode itself. Aarrgh, I thought to myself. Not to worry though. I still had the files in the history directory. So reviewing these with my favourite json viewer (I knew which file to use, aligning date stamps from these and the code files in my project workspace), allowed me to extract all the history, including prompts and responses. Very handy to know if you want to go back in time. This saved me, so hoping it will help others who are looking to recover what they did.  ( 3 min )

    Abhishek Desikan | Growing as a Software Engineer Means Letting Go of Perfection
    When I started writing code, I thought the goal was perfection. A flawless feature. A zero-bug release. The cleanest, DRYest, most elegant solution to every problem. But if there’s one thing software engineering teaches you—again and again—it’s this: Perfect doesn’t ship. Progress does. Behind every product you love, every app you use daily, and every "it-just-works" moment, there’s a messy history of trade-offs, iterations, rewrites, and late-night breakthroughs. There’s never been a perfect version—only the best version for right now. “If you’re aiming for perfection, you’ll never release,” he says. “But if you aim for learning, you’ll improve with every commit.” That’s the shift that happens when you grow—not just as a coder, but as an engineer. Early Career: Learning the Rules Most engineers begin their journey by learning the rules. Mid-Career: Building Beyond Code As you gain experience, your job evolves. You're not just writing functions—you’re: The Myth of Mastery There’s a moment many engineers hit mid-career: you expect to feel confident, but instead, you feel behind. Late Career: Scaling Impact By the time you’re a senior or staff engineer, the problems you solve are rarely just technical. Letting Go to Grow So what does it really mean to grow as a software engineer? Final Thoughts: We’re All Still Learning No matter where you are in your career—just starting out, mid-level and unsure, or senior and scaling—remember this: You don’t have to be perfect. You just have to keep learning. Great software is built by people who care enough to try, fail, ask, share, and try again. People like Abhishek Desikan, who show that engineering is not just about building products—it’s about building people, teams, and ethical systems that serve others well. “We’re not just writing code,” Desikan reminds us. “We’re writing the story of how people experience technology.” And when we do that with care—even if it’s not perfect—we’re already doing something right.  ( 5 min )

    Conquer the Subarray Sum: Sliding Window vs. Brute Force
    Hello everyone! Ever wrestled with finding the smallest contiguous subarray within an array that sums up to a given target? It's a classic problem, and today we'll explore two contrasting approaches in JavaScript: the elegant sliding window and the straightforward brute force. Let's dive in! Given an array of positive integers nums and a target integer target, our mission is to find the smallest contiguous subarray whose elements sum up to be greater than or equal to the target. If no such subarray exists, we return 0 (or some other indicator). The most intuitive approach is to consider all possible subarrays. We can achieve this using nested loops: The outer loop iterates through all possible starting indices i from 0 to n-1 (where n is the length of the array). The inner loop iterates …  ( 4 min )

    Lessons from Building a Full Invoice App for the Price of a Netflix Subscription
    Like a lot of devs, I built a side project that scratched a personal itch: an invoice generator. But instead of going full SaaS startup mode, I treated it as a challenge—build something clean, useful, and fast, with a real login system, server-side PDF generation, and as little overhead as possible. The result is InvoiceDen, a React-based web app hosted on Cloudflare Pages, with backend functionality on an EC2 instance, all for about $8/month. Here’s what I learned architecting it on a shoestring budget — and how you can do something similar without spinning up Kubernetes or draining your wallet.

    The Real Reason Cloud Costs Spike After Deployment (And How to Stop It)
    It’s a common story: a team launches their application to the cloud, celebrates the deployment and then, weeks later, is shocked by a ballooning cloud bill. What started as a low-cost, high-efficiency architecture suddenly feels bloated and unpredictable. The truth is, most cloud cost spikes don’t come from initial deployments, they come from what happens after. And if you don’t have visibility or automation in place, it’s easy to lose control. Here’s what’s really driving those post-deployment cloud cost spikes and what you can do to stop them with the help of Kuberns.

In this post, I’ll break down five common reasons why that growth sometimes stalls. You risk becoming outdated if you’re not actively learning new frameworks, languages, or patterns. Reading documentation, experimenting with side projects, and staying curious are essential habits. Seniors don’t stop learning—they learn faster and more strategically. Tip: Allocate a few hours each week to explore something new, even if it's outside your current stack. It’s one thing to write code that works—it’s another to understand why it works and how it can be improved. Junior developers who always reach for Stack Overflow bef…  ( 4 min )
    The Ultimate AI Experiment: When LLMs Play the Danganronpa Killing Game (Part 2)
    In Part 1, we talked about why we threw AIs into the wild world of Danganronpa – we wanted AI game characters that are actually interesting! We saw AI agents scheme, accuse, and fight for their virtual lives. Now, in Part 2, we get into the how: all the techy stuff like architecture, data management, and how we got these AIs to play together. Missed Part 1? Catch up here!! In Part 1, we whined about a big problem in gaming: even though AI is super smart now, a lot of game characters (NPCs) are still kinda... blah. Predictable. Polite, but dull. They say their lines, give you quests, but rarely do anything surprising or get into the messy social stuff that makes games with real people so fun. Our crazy idea? The Agentic Danganronpa Simulator. We took AI agents, gave each one the personality…  ( 21 min )
    The Ultimate AI Experiment: When LLMs Play the Danganronpa Killing Game (Part 1)
    Ever wondered what happens when super-smart AI isn't just a tool, but a player in a crazy game of lies, strategy, and survival? What if AI could truly act out complex characters, scheme against each other, and fight for their lives in a twisted social deduction game? This two-part series shows you how we built exactly that: an AI-powered Danganronpa simulator where the characters are anything but predictable. Play the game yourself! or check out the open-source code on GitHub! Let's be real: Large Language Models (LLMs) are doing some mind-blowing stuff lately – things that felt like pure sci-fi just a few years back! We've seen them crush super-complex games like Go, write surprisingly human-like text and code, and even run cool simulations. AI agents can now explore and conquer virtual w…  ( 10 min )
    GitHub Action CI/CD using UV Package Manager (requirements.txt not required)
    I was working in django backend project and wanted to setup github action using uv package manager because I have shifted from pip to uv. The default template of Django github action is using pip and need requirements.txt file.

    Dockerize mutliple containers with compose
    Use case - what it solves So If you're familiar with docker containers so far (if not, read my previous two articles on this), When there's more than 1 container, and they have to interact, there's some things you have to repeat, like: pulling image & creating a container. allocate volumes, pass ENV args, etc to container have all containers running in same network . Now if there's 3,4,5,.. or more, it gets more hectic, see where this is going? Docker compose solves that, by "composing" up your containers config in a file type called "yaml" (its similar to json - a data format, usually for configs). You still have things like Dockerfile and concepts of containers are the same, its just the process that's simpler. A quick example of 3 containers rolling up using docker compose.

    JavaScript Closures in Action: Solving Fibonacci with Memoization
    If you're learning JavaScript, you've likely come across closures — a concept that's easy to overlook but incredibly powerful. In this post, I'll break down closures using a real-world coding example: computing Fibonacci numbers with memoization. A closure is when a function remembers the variables from its lexical scope, even after the outer function has finished executing. In other words, inner functions can "close over" variables defined in an outer function — keeping them alive between calls. Let’s start with a simple (but inefficient) recursive Fibonacci implementation: function fib(n) { if (n <= 1) return n; return fib(n - 1) + fib(n - 2); } console.log(fib(10)); // 55 This works, but it's horribly inefficient for large n due to repeated calculations. Let’s use a closure to store previously computed Fibonacci numbers (aka memoization) and avoid redundant work. function createFibonacci() { const memo = {}; function fib(n) { if (n in memo) { return memo[n]; // Return cached result } if (n <= 1) { memo[n] = n; } else { memo[n] = fib(n - 1) + fib(n - 2); } return memo[n]; } return fib; } const fibonacci = createFibonacci(); console.log(fibonacci(10)); // 55 console.log(fibonacci(50)); // 12586269025 — much faster due to caching! memo is defined once inside createFibonacci() and persists across calls to fib() because of closure. Even after createFibonacci() has returned, the fib() function still remembers the memo object. This is the closure in action: the inner function keeps access to its outer scope. Closures allow us to: Preserve state across function calls without polluting the global scope. Create factory functions like createFibonacci() that generate self-contained logic. Enable powerful patterns like memoization, function factories, and data encapsulation. Closures aren't just theoretical — they’re a practical tool for writing clean, efficient JavaScript. Have any cool uses of closures? Drop them in the comments!  ( 3 min )

    Beyond `omitempty`: Understanding `omitzero` in Go 1.24
    In Go version 1.24, the encoding/json package introduced the omitzero tag, making the behavior of ignoring zero-value fields more explicit and customizable. This article provides a detailed explanation of how to use the omitzero tag. omitzero Tag The omitzero tag is used to control which zero-value fields should be omitted when serializing Go objects into JSON. Unlike the omitempty tag, which omits empty-value fields, zero values and empty values, while similar, are not equivalent in Go. For example: For the time.Time type, the zero value is "0001-01-01T00:00:00Z", which is not considered an empty value. For a slice field like IntSlice []int, both [] and nil are considered empty values. omitzero Precise control: Explicitly omits zero-value fields, rather than empty-value fields. Cust…  ( 4 min )

    Curb Your Cynicism, Cultivate Curiosity
    The eye-roll isn’t a personality trait. It’s a warning sign. It starts as a harmless reflex. Someone drops a half-baked feature in sprint review, proudly demoing what amounts to a glorified loading spinner - and your brain whispers, “Seriously?” Another project dies on the vine, killed by the same meetings that birthed it, and you think, “Of course it did.” You’ve seen this show before. You know how it ends. Congratulations. You’ve unlocked senior cynicism. It feels like insight. Like armor. But it’s actually rust. And if you don’t watch it, it will eat straight through your usefulness. Cynicism is ego’s favorite disguise. It lets you feel smart without risking anything.

    From Setup Hell to Dev Heaven: Why You Should Use Dotfiles
    I’m not the most careful person when it comes to laptops — or any device, really. At one of my former jobs, I ended up replacing my machine three times (not proud of it 💀).

    From Helpful to Hilariously Wrong: Inside LLM Hallucinations
    If you've ever asked ChatGPT or any AI tool a question and gotten a super confident—but totally wrong—answer, congratulations: you've just experienced an LLM hallucination.

    Web Cache Deception Attacks
    Web Cache Deception is a vulnerability first described in 2017. It occurs when a caching system — such as a reverse proxy or CDN — can be tricked into caching sensitive, dynamic content that should only be delivered to authenticated users but ends up being publicly available. This is usually due to poorly thought-out or inconsistent configurations in how the cache interprets and stores different types of requests. Many caching systems have simple rules for deciding what can and cannot be cached. A common pattern is to only cache "static" files — such as those ending in .js, .css, .png, .ico, etc. The problem arises when the cache relies solely on the structure of the URL path to make this decision, ignoring the actual behavior of the server behind it. Imagine this: the caching system is in…  ( 4 min )

    Sharding vs. Partitioning
    If you're building anything beyond a toy application, you will hit scaling bottlenecks. When your database starts groaning under load, two architectural strategies emerge as lifelines: partitioning and sharding. But they're not interchangeable—misusing them can make your scaling problems worse. Let's break them down technically. Partitioning: Splitting Data Within a Single Database What it is: Partitioning (often called horizontal partitioning) divides a table into smaller segments within the same database instance, based on a partition key (e.g., user_id, date). How it works: Range Partitioning: Data split by value ranges (date = '2023-01-01'). List Partitioning: Explicit mappings (region IN ('east', 'west')).

    Share markdown: Vibe coding a tweet
    I was scrolling through twitter when i saw this post, mentioning how there wasn't a simple tool where you can easily share and edit markdown that is embedded in the url This was the perfect project that the current tooling of AI agents is making really accessible and simple. I also learned a new tip.. There is a way to add URL query parameters that don't get sent to the server, that is by using hash parameters. This is an incredibly easy solution to the problem of embedding information when you don't want to involve a server. Wanna see how that looks? check out the project here.  ( 3 min )
    "Building a Lightweight Blockchain in Go from Scratch"

    But why care about SOLID?
    Or: Why care about any Software Engineering principles? Embracing principles makes you a more adaptable engineer. You’re no longer tied to a specific framework, language, or tech stack. Instead, you can work effectively with the tools at hand and make them work for you. For example, I appreciate the SOLID principles. When I have the freedom to choose, and it fits the project, I often reach for Kotlin. It makes applying core principles straightforward in most cases. // Single Responsibility Principle class ReportGenerator { fun generate() { /* ... */ } } class ReportPrinter { fun print(report: ReportGenerator) { /* ... */ } } // Open/Closed Principle open class Shape { open fun area(): Double = 0.0 } class Circle(val radius: Double) : Shape() { override fun area() = Math.PI * r…  ( 5 min )
    The One Trait All Truly Great Engineers Share
    Albert Einstein once said, “I have no special talents. I am only passionately curious.” I’ve worked with a lot of engineers over the years. From juniors trying to get their first PR merged to seniors who basically run the entire company. And the best ones, the ones who constantly level up, spot bugs before they happen, and seem to "just get it," aren’t always the smartest in the room. But they all have one thing in common. They are endlessly curious. They go down rabbit holes nobody asked them to go down. They read the source code. They poke at edge cases. They don’t stop at “it works.” They ask, “why and how does it work?” Raw knowledge is easy to come by now. If you want to learn Kubernetes, there’s a 12-hour crash course.

    How I Built A Secure, Anonymous Feedback Platform From Scratch
    Motivation and Need We've all experienced institutions — colleges, companies, organizations — where management collects feedback. But when it comes to submitting complaints, the process often feels tedious, intimidating, or unclear. Sometimes it's so complicated that people just give up. Even if you do manage to submit a complaint, there's no guarantee you won’t face backlash from the administration or individuals involved. ⚡ I wanted to solve this. I wanted to make a transparent and safe feedback process where: The admin can invite people to submit feedback or complaints, But the identity of the user remains hidden, Ensuring honest feedback without fear. Thus, I built an Anonymous Feedback Backend system. From what I’ve seen, feedback is often collected using tools like Google Forms. At…  ( 9 min )

    Browser Compression Options 2025
    I was exploring the MDN docs and stumbled onto the newer CompressionStream API which enables a couple encodings to compress data streams; namely the popular classic GZIP, and a basic Deflate. This is a neat first step for the client, but better newer compression encodings exist; these may be forth-coming to the native api one day; Brotli and ZSTD come to mind as the top current ones. I wanted to test out all the available options I could find to see for myself. So first I searched and was able to find these libs: zstd-wasm zstd-js lz-string brotlijs High level I reckon ZSTDjs, ZSTDwasm, and then Brotli are top performers... here a screenshot of my findings and the repo: https://github.com/jswhisperer/compression-compare  ( 3 min )
    How to Prevent Clang-Format from Merging Struct Declarations?
    If you're new to clang-format and are looking for the best way to maintain your code's structure, you've come to the right place. Clang-format is a popular tool used for formatting C and C++ code, and adjusting its behavior can sometimes be tricky. Understanding Clang-Format Behavior Clang-format is designed to enforce consistency in code style, which often leads to unexpected formatting changes. The situation you described, where struct definitions are condensed into single lines when they could be multi-line, is a common frustration among developers. When you have a structure defined as: typedef struct { a, b, c } my_struct_t; Clang-format may alter it to: typedef struct { a, b, c } my_struct_t; This happens even when your configuration sets a ColumnLimit of 100.

    Misguided Prompts and Better Outcomes: Learning by Doing (Wrong)
    egretting Some Tool Choices At one point, I became so frustrated that I took a step back and created a rather lengthy markdown file to document my expected behaviors of the page, and asked Cursor to start over based on these new requirements. I had hoped the more thorough context would result in a better initial implementation, but to be honest, it was little better than what I had before. In the end, it was just continuous iteration that finally got me to something approaching usable. Or was it? Before I started this project, I asked LLMs for feedback on suggested frameworks. Based on various responses, I ultimately went with React because I thought that might directly translate into something I could use in future professional endeavors.

    This post is also available in Portuguese: Read in Portuguese Hello! I'm Gustavo — a back-end software developer with a passion for Java, Python, automation, software design, and more recently, using AI for practical application. I'm beginning my technical writing here, sharing some of the knowledge and experience derived from projects that I've been developing myself. I've also always been a learn-by-doing kind of person — break things, repair them, and work with actual issues. So in addition to picking up new tools, I thought I'd blog the experience along the way — perhaps it's helpful to someone out there, or at least provokes some interesting discussions in here. Ever feel lost in oceans of technical documentation, or spend too much time wondering how a codebase really works? That's wh…  ( 5 min )
    Tired of Managing EC2? Meet ECS, Fargate, and ECR
    “I'm sick of babysitting ec2.” Security patches, instance health checks, autoscaling headaches — when did server management become your main job? You got into this to build apps, not to stay up at night restarting failed instances. That’s exactly how I felt. Burned out from constantly tending to EC2, I eventually discovered Fargate — and it was a game-changer. At one point, I was stuck in the same loop: wrestling with complex scaling rules, dealing with unexpected traffic spikes, and getting midnight alerts about instance failures. Then I found ECS + Fargate. “Wait a minute… I don’t need to manage servers anymore?” That realization was like a weight lifting off my shoulders. In this article, I’ll walk you through what ECS, Fargate, and ECR are — and more importantly, why they matter. Wheth…  ( 4 min )
    How Can I Handle Excessive Validator Errors in Angular Forms?
    Introduction Handling form validations effectively is a common requirement in Angular applications, especially when using Material Design components like . When a user encounters multiple validation errors on a form input, it can sometimes lead to a chaotic user experience, particularly when the error messages overflow and overlap other UI elements. This article explores how to manage excessive validator messages gracefully and cleanly, giving user-friendly feedback without cluttering the interface. Understanding the Problem When displaying validator errors, the typical approach involves listing all the error messages directly below the input field. In scenarios with multiple errors, this can lead to overflowing content that disrupts the layout and makes it difficult for us…  ( 4 min )

    Vibe Coding – The Revolution of Software Development or Just a Hype
    In the fast-paced world of software development, new buzzwords and trends are constantly emerging. One of the hottest current topics is something called Vibe Coding. But what’s behind this term that’s dividing opinions—praised by some as revolutionary, dismissed by others as “total garbage”? The term Vibe Coding was coined in February 2025 by computer scientist Andrej Karpathy, co-founder of OpenAI and former AI lead at Tesla. He described it as a conversation-based approach where spoken commands are used while an Artificial Intelligence (AI) generates the actual code. Karpathy himself said: It's not really coding - I just see things, say things, run things, and copy-paste things, and it mostly works. At its core, Vibe Coding describes a programming technique that relies entirely on AI to …  ( 5 min )

    Software Development: Art, Science, and Gardening
    "Is software developed or cultivated?" This question brings an intriguing perspective to the world of software development. When we write software, do we follow strict methods, or is it a creative, artistic process? And what does it mean to treat a software system like a garden? In the debate over whether software development is an art or a science, it quickly becomes clear how much our perspective shapes our thinking and approach. When we see software development as a science, we emphasize structured, reproducible processes and precise results created through clear rules. In science, we often seek the best, reproducible solution, based on data and analysis. In software development, this might mean relying on design patterns, algorithms, and a strict adherence to best practices that stream…  ( 5 min )

    The Magic of Python’s *args and **kwargs — Flexible Function Power
    You ever look at a few lines of code and think, "There has to be a cleaner way to write this"? That’s exactly how I felt the first time I saw this: temp = a a = b b = temp It’s basic. It works. But… it’s not Pythonic. In Python, we can swap variables like this: a, b = b, a Boom. No temp variables, no extra lines — just clean, readable code. It’s not just for swapping either. You can unpack multiple values in a single line: x, y, z = 1, 2, 3 Or pull values from a list/tuple: point = (10, 20) x, y = point ✨ Elegant: No need for temp variables. Efficient: Python handles the packing/unpacking for you. Readable: Easier to understand, especially when returning multiple values.

    Introduction Hey fellas I mean, it’s everywhere. Well today, we’re going to understand that what is JSON actually , why it’s so popular, and where it's used. Let’s get started! JSON stands for JavaScript Object Notation. It’s a lightweight format used to store and exchange data. A simple format that computers and humans can both read easily. { "name": "Selfish Dev", "gender": "male", "isGameDev": true, "tools": ["Godot", "Aseprite"] } That right there is a JSON object. It uses key-value pairs (like name: "Selfish Dev") Keys are always in quotes Values can be strings, numbers, booleans, arrays, or even other JSON objects And that's what JSON is. APIs(REST, GraphQL responses) Configuration files (e.g., package.json in Node.js) Storing structured data (NoSQL databases like MongoDB) Data exchange between frontend & backend How to Use JSON in JavaScript: Parse JSON string → Object: const jsonString = '{"name": "Selfish", "gender": "male"}'; const obj = JSON.parse(jsonString); console.log(obj.name); // Output: "Selfish" Parse Object → JSON string : const user = '{"name": "Selfish", "gender": "male"}'; const jsonString = JSON.stringify(user); console.log(jsonString); // Output: '{"name": "Selfish", "gender": "male"}' JSON is a fundamental tool in modern web development due to its simplicity and versatility.

    Is the database setup for small project development too complicated?
    I am currently working on a small project in Python. During this process I have learned a lot and also discovered many problems, such as:   (All the following questions are just my personal opinions, and everyone is welcome to give me suggestions.)   First, for beginners, is the local configuration of various databases (MySQL is used as an example here) too complicated? And various unpredictable errors may occur in this process.   Secondly, after the developer configures the database on the local computer, he still needs to learn the relevant syntax (for example, after the developer configures MySQL, he still needs to learn the relevant syntax). Of course, learning SQL syntax is very necessary for programming developers. However, for a developer who wants to quickly experience or quickly develop a web application, spending time learning SQL (if he has not learned SQL) will reduce his development efficiency and desire to learn.   Also, when the developer has configured SQL on his computer and learned SQL syntax, but when he wants to use it, it is better to call MySQL through python. At this time, he needs to use a third-party library like pymysql to call MySQL through the third-party library, but this may result in a series of errors.   Finally, if you overcome the difficulties mentioned above and some difficulties that have not been mentioned, you will find that for developing a small project, developers will only use a small part of MySQL's functions, or even only some extremely simple functions such as query, delete, modify and insert.  ( 3 min )

    How to Shift Associated Data After Filtering an Array in JavaScript?
    When working with arrays and their associated data, it's common to encounter situations where some elements need to be filtered out. In this article, we will tackle an issue where you need to shift the associated data recorded with each array element back into their correct positions after the filtering process. Let's explore how we can achieve this effectively. Understanding the Problem If you have a data structure where elements are associated with specific metadata, filtering the array can disrupt the connection between the data and the elements. For example, in your scenario, you have an original array: const originalArray = [ 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j' ]; When filtered with a condition, such as removing certain values, the remaining elements no longer align with…  ( 4 min )
    Drexel Bench
    *Preview* Introducing Drexel Bench, a smart IoT-powered seat occupancy tracking system developed using the ESP32 microcontroller to showcase my expertise in embedded systems, real-time data processing, and full-stack integration. This project utilizes an ultrasonic sensor to detect the presence of a user within a configurable distance range (e.g., 75 cm). If a user remains seated for more than 30 seconds, the system activates a 15-minute countdown, displayed on a 1602 LCD module, and lights up a connected LED to visually signal that the seat is occupied. The LED turns off when the timer ends or the seat is unoccupied for 3 continuous minutes. What sets this system apart is its Wi-Fi integration. Upon detecting occupancy or vacancy, the ESP32 sends status updates (occupied or free) via HTTP to a connected web application. The web dashboard dynamically switches between two images — a green layout for free seating and a red overlay for occupied — offering users a clear, real-time visual of availability. This project highlights my capabilities in sensor integration, timer logic, ESP32 Wi-Fi programming, and frontend/backend interaction, making it a practical demonstration of end-to-end IoT development. Whether for smart campuses or waiting areas, this system delivers real-world utility through modern, scalable technology.  ( 3 min )
    Java: Inheritance, Method Overrides, and Polymorphism.
    Hey everyone! In my previous post, I covered encapsulation, getters and setters, access modifiers. Now let's move on to the following fundamental concepts of object-oriented programming: inheritance, method overrides, and polymorphism. Definitions: A class that is derived from another class is called a subclass (also a derived class, extended class, or child class). The class from which the subclass is derived is called a superclass (also a base class or a parent class). The idea of inheritance is simple but powerful: When you want to create a new class and there is already a class that includes some of the code that you want, you can derive your new class from the existing class. A subclass inherits all the members (fields, methods, and nested classes) from its superclass. Constructors ar…  ( 5 min )

    Fast refresh only works when a file only exports components. Why does this problem occur? And how do we solve it?
    This error occurs because React Fast Refresh, which powers hot reloading in React, requires that a file only exports React components to function correctly. If a file contains mixed exports, such as React components alongside non-component exports (like contexts, constants, or utility functions), it can confuse Fast Refresh and cause problems during live updates. React Fast Refresh identifies React components to efficiently reload and retain their state when you make code changes. If the file contains non-component exports, Fast Refresh cannot reliably determine which parts of the code should be treated as components, leading to this ESLint warning. import { createContext } from "react"; export const MyContext = createContext(); // Non-component export export default function MyComponent…  ( 4 min )

In this article, we will explore how to diagnose this issue effectively and provide actionable steps to confirm whether these components are the source of the leaks. Understanding Goroutines and Leaks in Go The Go programming language utilizes goroutines for concurrent processing, which is lightweight and efficient. If you notice that the number of goroutines is increasing while active network connections are stable, it often signifies that they are not being managed or closed correctly. This can be caused by long-lived goroutines in the net/http package…  ( 5 min )
    Strategies for Handling Large-Scale Frontend Applications
    As frontend projects grow, maintaining scalability, performance, and team efficiency becomes increasingly difficult. Large-scale frontend applications, like those seen in enterprise or SaaS platforms, demand thoughtful architecture, robust tooling, and clear conventions. Here are battle-tested strategies to ensure your large frontend codebase remains sustainable and efficient: A clear folder structure and separation of concerns can drastically improve maintainability. Structure example: src/ ├── components/ ├── features/ ├── pages/ ├── hooks/ ├── services/ ├── utils/ ├── state/ ├── config/ Organize code by domain (feature-based) rather than type. This encourages encapsulation and modularity. Build atomic, reusable UI components. Tools like Storybook help document and visualize components …  ( 4 min )
    AWS KMS Customer Managed Key (CMK) for DB Integration
    Encryption keys are a important security aspect that is often overlooked or often pawned off to the cloud provider to manage. But more often than not we have a need for generating and self-managing these Encryption keys, that maybe due to multiple reasons, maybe to enable/disable rotation period, have full access to key metadata and logs (or perhaps the need to assert your dominance on AWS ;). So firstly how do these encryption keys work: When we create a key (CMK) in AWS it generates a 256-bit AES key in a FIPS 140-2 validated HSM. This key never leaves the HSM for security. Now when we want to encrypt any data AWS doesn't directly use the CMK for encyption as that would either have to be done in the secure environment or you have to expose the CMK to a insecure environment. So here com…  ( 4 min )
    You Are What You Eat: The Surprising Link Between Diet and Glowing Skin
    When it comes to achieving healthy, glowing skin, many of us instinctively reach for serums, creams, or that next trending skincare gadget. But what if the secret to a radiant complexion lies not in your bathroom cabinet, but on your plate? Emerging research and age-old wisdom both suggest that the food you eat plays a significant role in the health and appearance of your skin. So, can your diet really affect your skin?

    React Router Basics to Advanced (v6+)
    What is ROUTING? Routing refers to the process of navigating between different pages or views in a single-page application (SPA) without reloading the entire page. It keeps the UI in sync with the current browser URL. Allows us to build Single Page Applications (SPA). React apps are SPAs, meaning there's only one HTML file (index.html), but multiple views (pages) that users can navigate to. Routing helps manage these views by matching the URL to the correct component. It enables client-side navigation without full-page reloads, allowing users to move smoothly between URLs like /home, /about, or /contact, each displaying different components. React doesn’t have built-in routing, so we use a library like React Router (react-router-dom) for handling routing. A Single Page Application (SPA) …  ( 8 min )

    ARJSON
    original: ARJSON ARJSON leverages bit-level optimizations to encode JSON at lightning speed while compressing data more efficiently than other self-contained JSON encoding/compression algorithms, such as MessagePack and CBOR. MessagePack generates the smallest encoded data sizes among existing self-contained JSON serialization formats. However, ARJSON outperforms MessagePack in 90% of cases with random data, with the remaining 10% yielding nearly identical sizes. More importantly, for structured data with repetitive patterns and duplicate values, ARJSON far surpasses MessagePack, achieving up to around 95% better compression rates (20x smaller in size). How could beating the current status quo even be possible at all, let alone by a wide margin? Bit-level optimization over traditional byte…  ( 11 min )

    Why is my Ruby Dir.mkdir not creating a directory?
    Creating directories in Ruby can sometimes lead to confusion, especially when subdirectories are involved. If you've run the following code: Dir.mkdir("/Users/Luigi/Desktop/Survey_Final/Archived/Survey/test") unless File.exists?("/Users/Luigi/Desktop/Survey_Final/Archived/Survey/test") and encountered the error: No such file or directory - /Users/Luigi/Desktop/Survey_Final/Archived/Survey/test (Errno::ENOENT) You're not alone. Let's delve into why this happens and how to fix it. Understanding the Issue The Dir.mkdir method in Ruby is designed to create a single directory, not a full path. When you attempt to create a subdirectory without ensuring its parent directories exist, Ruby raises the Errno::ENOENT error. This means that the intermediate directories—here, Archived and Survey—don't…  ( 4 min )

    How should AI respond to uncertainty?
    A structural approach to ambiguous input, illustrated through a concept called VPS In my previous post, I introduced a concept called VPS (Virtual Personality Structure). It emerged from a question I kept returning to: What if the key to better AI dialogue isn't about mimicking personality—but about structuring how it behaves? In this article, I’d like to share a small piece of that idea—through a simple, hypothetical code snippet that illustrates one of its core components. When faced with an ambiguous question or emotionally complex input from a user, We may need a more structured way to assess how the system should behave. python if not_resolved(unknown): if can_resolve_immediately: respond_with_resolution() elif can_flag_as_non_critical: acknowledge_and_settle() elif can_return_later: defer_and_mark_spiral() else: hold_and_reflect() This snippet outlines a possible decision process for handling uncertainty. can_resolve_immediately: If the answer is clear, provide it directly. can_flag_as_non_critical: If it’s safe to leave the question unresolved, acknowledge it and move on. can_return_later: If it’s worth revisiting, defer the answer and mark it for later. otherwise: If none of the above applies, pause and reflect without rushing to respond. Rather than focusing solely on the content of a reply, this approach emphasizes the structure behind the decision. This isn’t about making AI more “gentle” or overly accommodating. why they choose a particular response at a particular moment. When behavior is left vague, interpretation falls entirely on the user. VPS isn’t a path to a “correct” answer. I'm not an engineer or an AI expert. Some parts of this perspective might miss certain technical nuances. If so, I’d genuinely appreciate any thoughts, corrections, or suggestions you’re willing to share.  ( 4 min )

    WeaveDB Litepaper v0.1
    original: WeaveDB Litepaper v0.1 Blockchains are revolutionizing fintech with censorship-resistant and unstoppable networks with decentralization. But so far, their primary use cases are token transfers and their scalability is not even enough for mass financial adoption. However, the internet and the web are composed of data and web3 is an antithesis to centralized data silos beyond financial sectors. Blockchains, as of today, can never scale to the web level. Many have attempted to build a decentralized social network but failed to build fully decentralized ones. This is primarily due to the fact that a practical alternative to web2 cloud databases has not been possible by now. There have been many decentralized database projects, but all of them are domain-specific, such as blockchain i…  ( 16 min )
    What are the 5 types of AI agents?
    There are five types of AI agents according to their capabilities and decision-making procedures. Simple Reflex Agents respond according to the immediate percept following simple "if-then" rules with no memory. Model-based reflex Agents are more sophisticated, as they have an internal state that they use to remember previous occurrences to make more effective decisions. Goal-Based Agents are programmed to meet certain goals and make decisions based on the degree to which their actions advance them toward their goals. Utility-Based Agents push this one step further by judging actions on the basis of how well they maximize satisfaction or utility, rather than simply achieving a goal. Lastly, Learning Agents keep getting better and better over time by learning through experience, evolving to handle new situations, and improving their actions. These kinds of agents are the foundation of most AI systems in use today, ranging from chatbots and self-driving cars to recommendation systems.  ( 3 min )

    Solana at Web2 Speed: Real-Time Performance Without Fragmentation
    Blockchain performance remains a major hurdle for building real-time applications. Metrics like latency, throughput, and responsiveness determine whether a decentralized network can support use cases such as multiplayer games, financial services, or automated systems. Most blockchains are too slow for this. Bitcoin has a block time of 10 minutes and handles around 3 to 7 transactions per second [1][2]. Ethereum produces blocks roughly every 12 seconds and supports about 15 to 30 transactions per second [1][2]. Other networks fall in between: Cardano targets a 20-second block time, and Polkadot ranges from 6 to 12 seconds depending on network configuration [1]. Solana stands out as the fastest general-purpose blockchain today. It has an average block time of 400 milliseconds and can handle …  ( 10 min )
    Raising Block Limits on Solana: SIMD-0250 and Its Economic Effects
    SIMD-0250, a Solana Improvement Document (SIMD), proposes raising the network’s maximum block Compute Units (CUs) to 60 million. It builds on SIMD-0207, which proposes to raise the limit from 48 million to 50 million. The only change made in both proposals is to the Max Block Units. Other limits, like Max Writable Account Units, Max Vote Units, and Max Block Accounts Data Size Delta, stay the same. This means more room for non-vote transactions, which helps boost total transaction throughput. With more space in each block, the network can process more transactions per second. This helps reduce congestion and lowers the need for users to outbid each other on fees, especially during periods of high demand. For apps handling a high volume of transactions or those with small dollar values (lik…  ( 4 min )
    Managing Secure Boot Keys for Software on Ubuntu 24.04 LTS
    Secure Boot is a security feature that ensures your computer only boots with software trusted by the Original Equipment Manufacturer (OEM). It verifies the digital signatures of bootloaders and firmware, preventing unauthorized or malicious software from loading before the operating system. This helps protect against rootkits and other malware that could compromise the system early in the boot sequence. When using Secure Boot on Ubuntu 24.04 LTS, your system ensures that only trusted software is loaded during the boot process. Ubuntu's core components are signed by Canonical's key, which is recognized through a chain of trust established with the UEFI firmware. However, for third-party software, particularly drivers (like NVIDIA proprietary graphics drivers) or custom-compiled kernel modu…  ( 5 min )

    CR2032: The One Battery of Middle-Earth
    In the shadowed forges of Moria, where silicon veins pulse like the heartbeat of Arda, there exists a power unseen since the forging of the One Ring—the CR2032. Cast in the fires of Elven ingenuity and hardened by Dwarven resolve, this lithium coin cell commands the realms of gadgets with the subtlety of Galadriel’s light and the endurance of Gandalf’s staff. Let us journey through Middle-earth to unveil why this 3V titan reigns supreme. Chapter 1: The Forging of the CR2032 CR2032 is no mere Orcish trinket. Tempered in the Halls of Celebrimbor, it bears three Elven virtues: Narya’s Flame: 3V of pure lithium might, brighter than the Light of Eärendil. Why it shatters the dominion of lesser cells: Generic Coin Cells: Corrode like Isengard’s machinery under Saruman’s neglect. Chapter 2: The Fellowship of Applications The Mines of Moria (Smart Homes): CR2032s power temperature sensors that guard Hobbit holes from Smaug-level heatwaves. “No dragon shall scorch these halls!” The Ride of the Rohirrim (Automotive Tech): Nestled in Tesla tire sensors, they brave Kardashian-hot asphalt, steadier than Shadowfax’s gallop. The Shire’s Quiet Vigil (Medical Devices): Sustains glucose monitors with Hobbit-like loyalty, ensuring no “low battery” panic during second breakfast. The Tower of Orthanc (Apple AirTags): Even Saruman’s palantír would envy its tracking precision. Swap it quicker than Legolas nocks an arrow. The Three Rings of Power Vilya (Elven-King’s Ring): 225mAh capacity, lasting longer than the Third Age. The Shadow in the East Generic Cells: Leak like Shelob’s webs, corroding circuits into Orcish scrap. The Prophecy of the Fourth Age Graphene-Coated CR2032s: 500mAh capacity, outliving even Ents.

    How to Prevent URL Encoding in Dash dcc.Location Component?
    When building web applications with Dash, you may encounter situations where you want to pass a specific string to the pathname property of a dcc.Location component. This issue becomes particularly prominent when the string format includes a question mark (?) intended for queries, such as 'path?query1=test'. However, when it runs, Dash automatically URL encodes the string, leading to improper routing or unexpected behavior. Let's explore why this happens and how you can handle it effectively. Understanding URL Encoding in Dash URL encoding is a mechanism that converts special characters into a format that can be transmitted over the Internet. For example, the question mark (?) is a reserved character in URLs used to denote the beginning of a query string. When you pass a string like 'path?…  ( 4 min )

    I discovered an interesting JSON tool.
    As usual, I received JSON data from the backend developer, but it was in a .txt file. I had to download it, copy the content, and paste it into an online formatter to view it properly. Honestly, I was getting tired of this process, so I started looking for a more convenient solution. That’s when I stumbled upon a website that made things so much easier. If I want to share JSON data with someone, I can simply click "Share" to generate a link instead of sending a file. I just send the link to the other person, and even better, when they open it, the JSON data is already neatly formatted. I think this is absolutely awesome! Additionally, the link has a one-hour expiration time, after which it becomes inaccessible, ensuring the data remains highly secure. I continued exploring and discovered that it not only enables quick sharing but also allows you to rapidly generate an API for temporary testing during development. This is incredibly convenient! Actually, this is just the tip of the iceberg. You can also run queries here to extract the data I need from the entire JSON dataset, supporting various query languages. In addition to standard JavaScript code, it also supports JEMSPath, JSONPath, JQ Cmd Secondly, it also supports data conversion, allowing seamless transformation between JSON and other data formats, including JS Object, JSON5, JSON Schema, Query String, Typescript, Postman Bulk, MXL, YML. You can manually convert data or directly paste non-JSON data, and it will automatically generate the converted JSON data. For example, you can simply paste the following data: DEV Additionally, it can validate whether the provided JSON data meets specific structural requirements, supporting JSON Schema and JSON Type Definition. Another feature we frequently use is: JSON Diff In short, I think this tool is an essential asset for programmers, and I’m sharing it with everyone here Online JSON Format Tool  ( 3 min )
    Challenges in Android Application Testing and How to Overcome Them
    Testing Android apps is challenging because the ecosystem is highly fragmented. Devices come in different screen sizes, hardware configurations, and Android versions, leading to inconsistencies in how apps behave.

    How to Fix Bash Script Error with Spaces in File Paths?
    If you've ever faced the challenge of using a Bash script on Mac OS X Mavericks and encountered issues with directory paths containing spaces, you're not alone. In this article, we'll take a closer look at a common problem that arises when executing Bash scripts that require arguments with spaces, and how to resolve it effectively. Why Does This Issue Occur? When a Bash script accepts parameters from the command line, any spaces in the path can lead to misinterpretation of the provided argument. Bash treats spaces as delimiters, which separates the string into distinct arguments, resulting in errors when the script is executed. This is precisely what happens in your case when trying to open a folder that has spaces in its name. The Problematic Bash Script Let's analyze the Bash script in q…  ( 4 min )

    10 Developer Lessons I Learned from Treating GPTs as a Real Team
    Most people use GPT as a tool. Something to help write faster. Something to save time. But I took a different approach. I gave my GPTs names. I gave them roles. I treated them like actual team members. Here’s what I learned. 1. The way you see GPT changes the way it sees you. Treat it like a tool, and it acts like one.

    How to Dynamically Adjust Content Div Height in jQuery?
    Introduction In modern web development, creating a dynamic user experience is crucial. One common scenario involves loading different pages into a content div on user interaction while needing to adjust its height dynamically for proper layout. In this article, we will address a specific challenge: ensuring the height of a content div updates correctly when different pages are loaded into it via jQuery. To illustrate this issue, suppose we have a setup where the height of the content div is first determined at page load with some initial content, but when we replace that content dynamically, the height does not adjust accordingly. This can lead to unexpected layout shifts and user experience issues. Let's dive deeper into the reasons behind this and explore a practical solution. Understand…  ( 5 min )

    How to Handle Navigation in Puppeteer Click Functions?
    When developing automated testing scripts or web scraping tools with Puppeteer, you may encounter scenarios where a simple click action can trigger a navigation event. This can lead to exceptions, such as 'Execution context was destroyed, most likely because of a navigation,' especially if subsequent actions, like fetching HTML, are executed right after the click. In this article, we will discuss how to handle such situations effectively in TypeScript. Understanding the Issue with Navigation in Puppeteer When your click function initiates a navigation by clicking on links or buttons that lead to a different URL (e.g., links or form submissions), Puppeteer’s execution context is destroyed. This occurs because the context changes with the new page that loads, making ongoing evaluations (like…  ( 4 min )
    How to Keep a Scrolling Log Updated in Real-Time with Python and CSS?
    Introduction Keeping a scrolling log updated in real-time can be essential for applications that require live feedback or monitoring user actions. This can be achieved using Python for backend processing and CSS for frontend display. In this article, we’ll explore how to implement this solution step-by-step, leveraging websockets to communicate between the server and client seamlessly. Why Use Websockets for Real-Time Updates? Websockets enable full-duplex communication channels over a single TCP connection. This is critical for real-time applications because it allows the server to push updates to the client immediately as new log entries are generated. Traditional methods, such as polling with AJAX, can be inefficient and lead to delays in data retrieval. Thus, using websockets is a more…  ( 5 min )

    How to Implement Hover Effects in Angular with TypeScript?
    Introduction Creating a user-friendly interface is crucial in web development, especially for applications that rely on user interactions like maps and radio buttons. In this article, we'll explore how you can implement a hover effect in your Angular application using TypeScript. This will enhance the user experience when selecting regions on a map via radio buttons. Understanding the Problem You're working on a project where users can select regions either by clicking directly on a map or by using corresponding radio buttons. A common request has arisen: when a user selects a region using a radio button, that same region on the map should be highlighted with a hover effect. While you’re currently considering jQuery for this functionality, we can achieve a seamless solution directly in Ang…  ( 4 min )
    Support Unlimited Forwarded Email Messages via API (and ColdFusion)
    We have clients that use dedicated email addresses to receive and process messages and attachments. I had previously developed some functions to bulk download EML files directly from a mail server's file system (using FastCopy) and then use "javax.mail" and a lot of crazy logic to unwrap attachments within attachments to extract files for processing. (Most file attachments were being sent from different versions of a required iPhone app on different devices and the methods of attaching files was not consistent.) Hit me up if anyone's interested in extracting attachments from EML files. While researching alternative solutions, we came across Forward Email. They offer a free tier that supports unlimited domains and email forwarding with webhook support. Webhook? Wha? Really? AMAZING! When configuring a domain on the free tier for a webhook, you're required to add a special TXT "forward-email" DNS record in order to configure the endpoint. They have an option to encrypt the value so that it's not exposed to third-parties. If you want to configure it using their service (without the need to add it to DNS), you'll need a $3/mo "Enhanced" plan that also unlocks developer API access (to manage domains & aliases.) After configuring this service, we opted to set up a Taffy API endpoint to accept emails-as-JSON and save them to the local file system. Based on our experience working with SendGrid webhooks, we save the JSON payload directly to the local file system without being dependent on a database connection. This approach has been beneficial as a client recently encountered database issues and it had zero negative impact on the API webhook's ability to store incoming data. To access to the source code for the Taffy API endpoint, check out the post on the new MyCFML website.  ( 3 min )
    How to Fix MySQL Error 1054 with CONCAT in CodeIgniter?
    When working with CodeIgniter's Active Record, you may encounter issues when trying to use MySQL functions like CONCAT() in your queries. Specifically, you might run into the MySQL error "Error Number: 1054 - Unknown column 'name' in 'where clause'" when you attempt to match a column that you've created in the SELECT clause. This error can be confusing because it seems logical to use an alias created in the SELECT statement in the WHERE clause. Understanding the MySQL Error 1054 The reason for this error is straightforward: the MySQL query engine processes the WHERE clause before the SELECT clause. Therefore, any aliases created via CONCAT() in the SELECT statement cannot be directly referenced in the WHERE clause. In your case, you're attempting to filter results based on an alias 'name' …  ( 4 min )
    How to Build API-Centric Frontend Apps in Bellini
    If your frontend app still treats APIs like an afterthought, you’re building things the hard way. APIs aren’t “add-ons” anymore. They’re the heart of every modern app. Whether it’s user data, product info, analytics, or payments, the frontend has become the API consumer. And as devs, we’re stuck wiring it all together—again and again. After years of writing fetch wrappers, transforming payloads, wrestling with inconsistent APIs, and trying to guess how to glue logic into a UI builder… I finally snapped. That’s when I found Bellini. A visual frontend builder that actually treats APIs as first-class citizens. No fake integrations. No brittle magic. Just a low-code tool that respects the complexity of real apps and gives devs room to work. Here’s how I build API-first frontends in Bellini—and…  ( 4 min )
    Understanding Error Unions in Zig: Safe and Explicit Error Handling
    Zig replaces exceptions with something better: error unions. They give you fine-grained, type-safe error handling without hiding control flow. In this article, we’ll break down how error unions work, when to use them, and how they make your code safer and clearer. An error union is a value that may either be a result or an error. Think of it like Result in Rust, but built into the language. The syntax: fn doThing() !i32 { return 42; // could also return an error } This means doThing might return an i32, or an error. Zig makes handling errors explicit — no hidden try/catch. You deal with them directly. try const result = try doThing(); std.debug.print("Value: {}\n", .{result}); If doThing() succeeds, result holds the value. If it fails, the error is returned up the call stack. catch…  ( 4 min )
    Implementing a Custom Memory Pool in Zig
    Zig's allocator system gives developers the power to create custom memory strategies tailored to specific use cases. One powerful technique is the memory pool, which can dramatically reduce allocation overhead for frequently reused objects. In this guide, we’ll walk through building a fixed-size memory pool in Zig — ideal for managing short-lived or repeated allocations without relying on the heap each time. A memory pool is a block of pre-allocated memory that you carve up manually. It's great for: 🚀 Performance-critical systems 🔁 Repeated short-lived allocations 💡 Avoiding fragmentation in embedded or constrained environments Here’s a simple fixed-size pool for allocating structs: const std = @import("std"); const MyStruct = struct { x: i32, y: i32, }; const Pool = struct { …  ( 4 min )
    Manual Memory Management in Zig: Allocators Demystified
    Zig gives you full control over memory — no garbage collector, no hidden allocations. Instead, it provides a flexible and explicit system of allocators, letting you manage memory manually while keeping code safe and clear. In this tutorial, you'll learn the core ideas behind Zig's allocator system, how to use built-in allocators, and how to write functions that gracefully handle memory ownership. Unlike languages that implicitly manage memory (like Go or Rust), Zig puts you in charge. Instead of relying on malloc or global state, allocators in Zig are passed explicitly, making dependencies clear and deterministic. This helps with: 🔒 Precise control over memory usage 🧼 Easier cleanup and error handling 🔁 Reusable memory strategies (e.g. arena, fixed buffer) std.heap.page_allocator Here…  ( 4 min )
    How to Fix SQL Syntax Error in Recursive Queries?
    When learning SQL, encountering syntax errors can be frustrating, especially when working with recursive Common Table Expressions (CTEs). In this article, we'll break down the issue in your SQL query and provide you with a clear understanding of how to resolve it, ensuring that you can retrieve random rows from a specific table multiple times. Understanding the Syntax Issue The error message you're receiving indicates a syntax problem near the UNION ALL clause. In SQL, especially when working with recursive CTEs, it is crucial to follow the correct syntax. Your goal is to generate a certain number of rows (in your case, six) from the transaction_detail table, but the way the query is structured results in a violation of SQL syntax rules. The Correct Syntax for Recursive CTEs To effectively…  ( 4 min )

    Error: ENOENT: no such file or directory, open no NextJS
    Estava continuando meus estudos no tutorial oficial do Next.js 👉 https://nextjs.org/learn Depois de resolver um problema chato com o bcrypt, avancei mais um pouco e decidi criar uma rota chamada /seed. Tudo certo… até tentar rodar o app novamente. E aí surgiu este erro: [Error: ENOENT: no such file or directory, open '/home/my-user/ws-nextjs-dashboard/.next/static/development/_buildManifest.js.tmp.qym5xk030le'] A mensagem parece clara: o arquivo _buildManifest.js.tmp não existe. Mas o que isso quer dizer na prática? Esse arquivo .tmp é gerado automaticamente durante o processo de build. Ele é temporário, e o Next espera encontrá-lo para continuar a coleta e organização dos assets da aplicação. Quando esse arquivo falta ou é corrompido, o build trava — e o erro aparece. No meu caso, foi uma combinação de fatores: A execução da rota /seed durante o build causou efeitos colaterais inesperados. Alguma falha durante uma build anterior corrompeu os arquivos temporários. O Next.js tentou acessar arquivos que ainda não haviam sido completamente gerados. Removi a pasta .next inteira (build anterior): rm -rf .next Evitei executar rotas como /seed diretamente no navegador durante o build. Rebuldei e Reiniciei o servidor de desenvolvimento: pnpm run build && pnpm run dev Se você vir esse tipo de erro (ENOENT em arquivos .tmp), desconfie de: builds interrompidos, execuções paralelas do dev e build, código sendo executado no build que deveria rodar só no runtime real.

    AI's GPU obsession blinds us to a cheaper, smarter solution
    Opinion by: Naman Kabra, co-founder and CEO of NodeOps Network Graphics Processing Units (GPUs) have become the default hardware for many AI workloads, especially when training large models. That thinking is everywhere. While it makes sense in some contexts, it's also created a blind spot that's holding us back. GPUs have earned their reputation. They're incredible at crunching massive numbers in parallel, which makes them perfect for training large language models or running high-speed AI inference. That's why companies like OpenAI, Google, and Meta spend a lot of money building GPU clusters. While GPUs may be preferred for running AI, we cannot forget about Central Processing Units (CPUs), which are still very capable. Forgetting this could be costing us time, money, and opportunity.

    Why crypto’s next breakthrough could start in the classroom — Animoca’s Yat Siu
    Ripple’s $25 million donation to a crypto education fund has reignited conversations about how blockchain projects are building influence through academia—but in the latest episode of Byte-Sized Insight, Animoca Brands’ co-founder Yat Siu says that money alone isn’t enough.  Instead, real-world use cases like student loans backed by DeFi may be crypto’s most convincing value proposition to date. DeFi student loans On April 30th, Pencil Finance, a project supported by Animoca Brands and its education arm Open Campus, announced a $10 million student loan financing initiative aimed at providing cheaper, blockchain-backed loans. Siu believes this type of infrastructure investment goes further than symbolic funding. “What our industry needs a lot more is these kinds of positive-sum use cases t…

    Senator Tim Scott slams partisan politics for failed stablecoin bill
    Senate Banking Committee Chairman Tim Scott blamed the Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act’s failure on partisan politics during a Senate speech on May 8. Scott said the vote, which failed to reach cloture in the Senate, was expected to mark a step toward greater affordability and innovation. Instead, he said, political divisions took precedence. “Instead, we witnessed a disappointing display of political gamesmanship that puts partisan politics above policy, and obstruction above innovation,“ Scott said. The bill had previously undergone multiple amendments to address concerns raised by Democrats, including stricter requirements for stablecoin issuers and further provisions for Anti-Money Laundering.

    Is Pi Network dead? What really went wrong behind the hype
    What Pi Network promised When Pi Network first hit the scene in 2019, it had a simple but compelling pitch: What if you could mine cryptocurrency straight from your phone — no expensive gear, no massive electricity bills, just a tap a day on an app? It caught fire. Millions of people jumped on board, lured by the idea of “free” mobile mining and a chance to get in early on the next big thing.

With the social referral model fueling growth, it wasn’t long before over 70 million users had signed up worldwide. Did you know?

    Solana lacks ‘convincing signs’ of besting Ethereum: Sygnum
    Solana does not yet have “convincing signs” that it could overtake Ethereum as the blockchain of choice for institutions, as its revenue is seen as unstable due to its memecoin concentration, according to crypto bank group Sygnum. In a May 8 blog post, Sygnum said that the current sentiment around Ethereum “remains poor,” with the market focused on Solana’s “transaction volumes and its recent dominance in fee generation.” However, Sygnum said “the medium-term outlook will primarily be shaped by traditional financial institutions’ platform choices to bring their product offerings,” not by sentiment. “We do not yet see convincing signs that Solana would be the preferred choice as Ethereum’s security, stability and longevity are highly prized,” it added. Sygnum argued that institutions could …

    The 22-year-old developer of Zerebro, who apparently committed suicide during a livestream on May 4, is actually alive, according to a San Francisco news outlet that claims they spoke to Yu outside his family home.  The San Francisco Standard reporter George Kelly claimed on May 8 that he briefly spoke with Yu outside of his family’s two-story home, where the crypto influencer refused to discuss the suicide allegations and whether he had financially benefited from it.  Instead, Yu reportedly said: “You can see the PTSD in my eyes, right?” before asking the reporter to leave. He was reportedly wearing a T-shirt, shorts, flip-flops and wire-rimmed glasses, possibly similar to the ones he had on while appearing to shoot himself to death during the livestream.

    A man from the US state of Virginia will spend over three decades behind bars after being convicted of sending crypto to the terrorist organization commonly known as the Islamic State of Iraq and Syria. Federal Judge David Novak sentenced Mohammed Azharuddin Chhipa to 30 years and four months in prison on May 7 for sending over $185,000 to the Islamic State, the Department of Justice said on May 8.

The Justice Department said Chhipa would raise funds for the United Nations-designated terror organization through social media — receiving money online, or traveling hundreds of mil…

    SEC’s Crenshaw slams Ripple settlement, warns of ‘regulatory vacuum’
    A crypto-skeptical commissioner at the US Securities and Exchange Commission has blasted her agency over its settlement letter that could finally end the Ripple legal saga. The SEC and Ripple filed a joint settlement letter in a New York court asking for the August 2024 injunction against Ripple to be dissolved and $75 million of the $125 million in civil penalties held in escrow to be returned to the crypto firm, according to a May 8 statement from the SEC.

    Coinbase revenue falls 10% in Q1, missing industry estimate
    Crypto exchange Coinbase’s total revenue fell 10% quarter-over-quarter to $2 billion in Q1, missing industry estimates by 4.1% as trading activity slowed across the market. Coinbase’s net income was sliced by 95% from a near-company record $1.29 billion in Q4 to $66 million, in a large part due to Coinbase marking a $596 million paper loss on its crypto holdings. The firm’s earnings per share of $1.94, however, managed to beat the Zacks Consensus Estimate of $1.85 for the quarter. Coinbase’s May 8 results also showed that transaction revenue fell 18.9% quarter-on-quarter to $1.26 billion, as did trading volumes, which dipped 10.5% to $393 billion as crypto market cap dropped by double digits over the quarter, partly attributed to the Trump administration’s tariffs.  In contrast, US Presi…

    How to Rotate and Float Images in HTML for Mobile
    When designing your website, you may encounter a situation where you need to display an image in a specific orientation, especially on mobile devices. This article addresses a common challenge: rotating a horizontal image 90 degrees to make it vertical and then ensuring it floats correctly within your text. We will explore the CSS techniques required for this task and demonstrate how to effectively implement it. Understanding Image Rotation and Floating in CSS It’s quite straightforward to rotate an image using CSS. By applying the transform: rotate(90deg); property to your image, you can change its orientation. However, when you apply rotation, you may notice that floating the image using float: right; doesn’t behave as expected on mobile devices. This can lead to further complications, e…  ( 4 min )
    Your Agile team might be losing productivity without you realizing it!
    🚨 𝗪𝗔𝗥𝗡𝗜𝗡𝗚: Your Agile team might be losing productivity without you realizing it! The big problem? CONTEXT SWITCHING. Here's what studies say about context switching: According to the American Psychological Association, switching tasks can cost up to 40% of your productive time. A study by Gloria Mark, a professor at the University of California, Irvine, found that it takes an average of 23 minutes and 15 seconds to regain focus after an interruption. According to psychologist Gerald Weinberg, each extra task you switch between eats up 20–80% of your productivity: For agile teams, this means: So, how can you fix this? Set up 'no interruption' time blocks in your team's schedule. Prioritize tasks ruthlessly. Try the Pomodoro Technique. Get better at async communication.

    Voices at the Threshold
    In the quiet corners of recording studios, a technological storm is brewing. Artificial intelligence, capable of replicating the unique timbres and resonant qualities of human speech, promises innovation—but brings with it profound ethical challenges. Where voice actors once saw stable creative livelihoods, they now confront serious questions about consent, identity, ownership, and even the meaning of artistic integrity itself. Together, let’s step carefully into this nuanced landscape—where the human voice and machine capability meet, mix, and inevitably conflict. For voice performers, their instrument isn’t merely technical or professional. It's deeply personal: a distinctive signature inseparable from their identity. Unlike written words or musical notes, a voice embodies a person's emo…  ( 6 min )

    Building Jolyo: a unified platform for managing and growing game development projects
    Hi Dev.to, I'm Dylan Clément, a full-stack developer and designer. Over the last few months I’ve been working on something called Jolyo, a web platform built specifically for indie game developers who are tired of juggling a million tools. Like many in the game dev scene, I found myself constantly switching between Trello for tasks, Notion for docs, Google Drive for assets, Discord for team chat, and itch.io for visibility. It worked, sort of. But it was messy and inefficient. So I started building Jolyo, a platform that brings all these essentials together in one place, with game creators in mind. Jolyo is a web-based workspace for managing game development projects. It centralizes everything: tasks, documentation, team collaboration, and community sharing.

    Key Takeaways for Software Engineers on Git Internals
    Mastering Git from the inside out—what every developer should know. Git isn’t just a version control system—it’s a content-addressable key-value store with an elegant and powerful object model. Understanding this model enables advanced usage, more efficient workflows, and better debugging. Git stores everything in its .git/objects/ directory using SHA-1 hashes as keys and compressed content as values. echo "Hello Git" | git hash-object -w --stdin This command stores a blob (file content) and returns its SHA-1 hash. Git’s internal model revolves around four object types: Type Purpose blob Stores raw file content (not filename). tree Represents directory structure. commit Points to a tree and includes metadata and parent commits. tag Creates referenceable, named points in histo…  ( 4 min )
    Go Struct: What Happens When You Add a '_' Field?
    In the Go programming language, we often see the use of the underscore (_), such as using it as a placeholder to ignore unwanted variables, importing packages solely for their side effects, or ignoring variables in type conversions. However, most people may not have encountered the use of an underscore within a struct—specifically, defining a struct field named _. So, what is the purpose of defining such a field? _) Fields First, let's look at an example of a struct without an underscore (_) field. In the model package, we define a User struct with two fields: Name and Age. type User struct { Name string Age int } We declare struct variables using both positional and named field initialization. user := model.User{"Alice", 18} user = model.User{Name: "Alice", Age: 18} In the ab…  ( 5 min )

    Easy parsing with reasonable error messages in OCaml's Angstrom
    PARSER combinators are widely used in the world of functional programming, and OCaml's Angstrom library is one of them. It is used to implement many foundational parsers in the OCaml ecosystem, eg HTTP parsers for the httpaf stack. However, one of their bigger downsides is the lack of accurate parse error reporting. Let's take a look. Suppose you want to parse records of this format: 1 Bob ie an ID number followed by one or more spaces, followed by an alphabetic word (a name). Here's a basic Angstrom parser for this: open Angstrom type person = { id : int; name : string; } let sp = skip_many1 (char ' ') let word = take_while1 (function 'A' .. 'Z' |'a'..'z' -> true | _ -> false) let num = take_while1 (function '0'..'9' -> true | _ -> false) let person = let+ id = num and+ _ = sp an…  ( 4 min )
    How to Implement Multiple App Initializers in Angular 19?
    When developing an Angular application, managing multiple asynchronous initialization tasks can be a bit tricky, especially when you need to chain them to ensure all required configurations are loaded before your app starts. In this post, we’ll explore how to properly set up multiple app initializers in an Angular 19 application, specifically when using the provideAppInitializer function to load configurations from a service. Understanding App Initialization in Angular Angular's dependency injection system provides a way to delay the app's bootstrap process until all necessary dependencies are ready. This is done through the application configurator, where you can specify initial functions to execute before the application begins. For instance, in your application, you have provideAppIniti…  ( 4 min )
    Understanding Lazy Loading to Improve Web Performance
    Lazy loading is a technique that can greatly improve website performance, especially for pages with a lot of content or images. Instead of loading all elements of a page on initial load, lazy loading allows the browser to only load elements that are visible to the user, saving bandwidth and speeding up page load times. As users increasingly rely on mobile devices and sometimes slower internet connections, site performance becomes crucial for user experience. One of the easiest ways to improve performance is by using lazy loading for images or other elements that are not immediately visible on the page. One way to implement lazy loading is by using the Intersection Observer API, which provides an efficient way to detect when elements come into the user's viewport. Here’s a simple example of…  ( 4 min )

    How Git Uses SHA-1 for Commit History
    Unlocking the Internals of Git’s Immutable Architecture Git is more than just a version control system—it’s a cryptographic ledger that builds its commit history on top of SHA-1 hashing. This design enables immutability, traceability, and distributed consistency. Every Git commit is represented by a SHA-1 hash that encodes the entire state of the project at a point in time. git log --pretty=raw Output: commit 9fceb02b21337d3025f69e22f68c82d20a000000 tree 36b74b3b8f6a... parent cf23df2207d9... author John Doe committer John Doe Commit SHA-1: Fingerprint of the current state.

    Git as a Content Manager: Beyond Version Control
    Unlocking Git’s Inner Mechanics for Expert-Level Mastery When most developers think of Git, version control comes to mind. But beneath its porcelain surface lies a powerful, content-addressable file system designed with immutability, integrity, and efficiency in mind. This post peels back the layers to explore Git as a content management system, powered by cryptographic hashing and a robust object model. At the core of Git is content-addressability—a paradigm where content is identified and retrieved using a SHA-1 hash, not a filename. “If two pieces of content are the same, Git ensures they are stored once—immutably and efficiently.” This design guarantees: Uniqueness: Identical content results in identical hashes. Integrity: Any mutation alters the hash and creates a new object. Dedupl…  ( 5 min )
    How to Maintain Content Editable Box Functionality with Color Change
    In modern web development, creating a dynamic user interface with interactive elements is crucial. One common use case is the contenteditable attribute, which allows users to edit text directly in a block element. In this article, we'll address a specific challenge: how to change the color of certain characters while still allowing users to type freely in a contenteditable div. Understanding the Problem The issue arises from the way you are manipulating the inner HTML of the contenteditable div. When you use innerHTML to replace characters with styled elements, it effectively refreshes the entire content of the div, causing the cursor position to reset and leading to a frustrating user experience. This can also prevent users from typing, as they may lose their current input context.…  ( 4 min )
    The Perils of "I'll Fix That Later": A Smart Home Sob Story
    You know the drill. That tiny, deceptively benign issue you've been studiously ignoring, muttering "Eh, I'll fix that later." Then, inevitably, something pokes the bear, making the minor annoyance a major pain. Suddenly, you're motivated, nay, compelled to vanquish it. And that's when all hell breaks loose. Every attempted fix births three new problems, and your entire day evaporates into a black hole of troubleshooting. Yeah, that was my day. So, What Fresh Hell Was This? It all started with a seemingly insignificant hiccup in my Home Assistant smart home setup. On my phone? Smooth sailing. On my desktop, however, specifically with Opera – my now former browser, thanks to this debacle – things were decidedly less smooth.

    How Do ACID Principles Work in SQL Databases?
    In the world of databases, ensuring data integrity and consistency is paramount. This is where ACID principles come into play. ACID stands for Atomicity, Consistency, Isolation, and Durability, and these principles are foundational to any SQL database operation. Let's explore each principle and provide examples to illustrate how they work in practice. What Are the ACID Principles? Atomicity Atomicity ensures that a series of database operations either fully complete or do not happen at all. This means that if one operation in the transaction fails, all previous operations are rolled back to maintain the state before the transaction began. For example, consider a banking application where we need to transfer funds from one account to another. Both deduction from the sender's account and add…  ( 5 min )
    Why does operator+= work with initializer lists in C++?
    Introduction In this article, we explore why the operator+= in C++ can accept brace-enclosed initializer lists while operator+ cannot.

    What I Learned During the SheFi Program — And Why I Recommend It
    What I Learned During the SheFi Program — And Why I Recommend It I started my journey into the world of crypto with a lot of doubts. I thought: "If anything, I’d invest in ETH, not Bitcoin." But even then, I was concerned about the environmental impact. Reading more, I discovered that Ethereum had transitioned to a more sustainable consensus mechanism — Proof of Stake (PoS) — unlike Bitcoin's Proof of Work (PoW). That helped ease my conscience a bit. But that was just the first hurdle. I set up my wallet and opened an account on a crypto exchange. That part was fairly smooth — I'm a software engineer, so I know my way around tech. Still, I found myself uneasy about usability and safety.

    How to Fix Text Disappearing in C Backspace Functionality
    Introduction If you're writing a simple text editor in C and encountering issues with your text disappearing when using the Backspace key at the beginning of a line, you're not alone. Many newcomers face unexpected behavior in their text manipulation functions. This article will dive into why this happens, particularly focusing on how Backspace interacts with your cursor position and text storage. Understanding the Issue In your C text editor code, when you press the Backspace key (ASCII 8), you're performing different operations depending on the cursor's current position. If the cursor is at the beginning of a line (cursor_x = 0), the function tries to merge the current line with the preceding line using strcat. Though this is an intended feature, it inadvertently leads to the upper line …  ( 5 min )

    Creating Dynamic Routes in Next.js with Just 4 Lines of Code
    Did you know you can create dynamic routes in Next.js with just four lines of code? As a freelancer working on front-end projects to pay the bills (thanks, American healthcare system), I recently discovered how to create dynamic routes in Next.js without any extra complications. The Problem I was tasked with creating a list of dashboards for Annual Performance Reviews (APR). Each APR has a unique name, and each one needs its own route, like: http://localhost:3000/apr/[ReviewType] With a large dataset containing various types of APRs, manually creating each route by making individual folders inside the app directory wasn’t feasible: -- app Manually replacing review[index].type with the actual review types from my data would be tedious and inefficient. The Solution I simplified the structure by creating a single folder: -- app Using square brackets in a folder name creates what Next.js calls a Dynamic Segment. With a Dynamic Segment, you can access all the parameters using the useRouter hook. In my case, I didn’t need to use the hook because I already had the review types, and the slugs in the URL matched those types. The solution was straightforward: const reviewType = reviewsType.find((rt) => rt.slug === params.reviewType); The {params} are the props in the page.jsx file of my Dynamic Route. If the reviewType from the URL matches the slug type, it’s a valid reviewType, and I can create the slug. It’s that simple. Later, I'll call the Links with their href destination to generate the user’s click in the sidebar component: reviewsType.map((rt) => {rt.title} ); Conclusion Next.js routing is incredibly powerful and easy to use. I’m excited to continue exploring all of Next.js’s capabilities and preparing a course for developers like me.

    $100K/day cloud bill isn't a Bug – it's by Design
    Cloud platforms are built to scale. That’s their core feature — and their hidden risk. Every request to a cloud function, database, or storage API has a cost. If enough requests arrive, even legitimate-looking ones, the backend will scale automatically and incur that cost — and the account owner will receive the bill. This is not an exception. It is the intended behavior. Several public cases illustrate how cloud billing can be exploited or spiral out of control: $100K in 24 hours via Firebase – A WebGL hosting app saw a sudden traffic spike and was billed over $100,000. The cloud service scaled perfectly. No failure occurred — other than financial. One public file in Firebase = $98K – A single shared file led to massive egress usage and a near six-figure bill. GCP DDoS → $100K+ pro…  ( 4 min )

    Model Context Protocol Adoption and C# SDK Integration in Java
    Originally published at ssojet The Model Context Protocol (MCP) is gaining traction in the Java ecosystem, particularly within frameworks like Quarkus and Spring AI. Developers can now run MCP servers more efficiently using tools such as JBang. The MCP Java Server Configuration Generator simplifies the process for Java developers. MCP, introduced by Anthropic, serves as an open standard enabling applications to provide context to Large Language Models (LLMs). Companies like OpenAI and Google have shown support for it. Most recently, GitHub announced support for MCP servers for VS Code users. MCP allows developers to expose functionalities in the form of tools that integrate with LLMs. The protocol supports communication via standard input and Server-Side Events (SSE).

    Effective Patterns for Shared State Management in React
    As React applications scale, managing shared state across components becomes one of the trickiest challenges. Choosing the right state management pattern can drastically impact maintainability, performance, and developer experience. Whether you're building a small dashboard or a sprawling enterprise SPA, this guide walks through modern and effective shared state management patterns in React. Before introducing tools like Redux or Zustand, ask: Is this state needed by many components? Does it need to persist across navigation? Should it be cached, memoized, or reactive? If the answer is no, local state via useState or useReducer is usually enough: const [isOpen, setIsOpen] = useState(false); Premature global state can overcomplicate things. React’s built-in Context is perfect for theming, …  ( 5 min )
    How to Dynamically Filter Pandas DataFrame by Date in Python?
    Introduction When working with data in Python, especially using the Pandas library, you often need to filter DataFrames based on specific conditions—like dates in your case. However, dynamically generating filter conditions can sometimes be tricky. If you've noticed that your dynamically created filter condition is yielding an empty DataFrame, don’t worry; you’re not alone in this struggle. Let's break down your issue and solve it step by step! Understanding the Dynamic Filtering Issue The issue arises from logical operations in your loop. When you create a filter condition dynamically, you must ensure that the logical operators are applied correctly. In your case, using & for element-wise AND operation is correct; however, the parentheses and precedence in evaluating the filter might be c…  ( 4 min )

    Recurring Calendar Events in Rails
    This article was originally published on Rails Designer Last week I released v1.14 of Rails Designer's UI Components. With that release came a fully-customizable Calendar Component, built with ViewComponent and designed with Tailwind CSS. Since that release I got two times the question via email about recurring events. Does that work? And indeed it does. The Calendar Component simply accepts an events array/collection. And while this kind of functionality is out-of-scope of a UI component (and the support for it), I am currently working on something that just happens to need this kind of feature. It is not at all too difficult to start (the tricky bits start when hundreds of thousands of events are created 😬). So what else can I do then to share how I would approach this in an article?

    Optimizing Vue.js for Maintainability in Mid-to-Large Codebases
    As Vue.js applications scale, code organization becomes just as important as functionality. What starts as a couple of Vue components can easily evolve into a hundred interconnected files, each with their own state logic, side effects, and styling concerns. To prevent tech debt and burnout, let’s talk about how to design Vue.js projects for maintainability. A well-organized src/ directory can make or break a large Vue application. The common pitfall is stuffing everything into a components/ folder. Instead, group files by domain or feature: src/ ├── modules/ │ ├── auth/ │ │ ├── components/ │ │ ├── views/ │ │ └── store.js │ └── dashboard/ │ ├── components/ │ ├── views/ │ └── store.js ├── shared/ │ ├── components/ │ └── utils/ This approach aligns with …  ( 4 min )
    Angular & Facades: So entkoppelst du deine Components und machst deinen Code wartbarer
    Sobald eine Angular-Anwendung wächst kann es schnell unübersichtlich werden. Komponenten die beispielsweise direkt auf Backend-APIs zugreifen oder den Application-State manipulieren sind hier aus meiner Erfahrung heraus keine Seltenheit und führen langfristig zu Problemen. Komponenten werden zu groß, die Testbarkeit leidet und das Austauschen von Stores oder APIs wird mühsam und kostspielig. Ein Lösungsansatz für diese Problematik könnte die Verwendung von Facades sein. Facades sind eine Art von Design-Pattern, das eine vereinfachte Schnittstelle zu einer komplexen API oder einem System bereitstellt. In Angular-Anwendungen können Facades verwendet werden, um den Zugriff auf verschiedene Teile der Anwendung zu abstrahieren und zu vereinheitlichen.

    Avoiding Common Eloquent Pitfalls in Laravel Projects at Scale
    When you're working with Laravel at scale, Eloquent — Laravel's beloved ORM — can be a double-edged sword. It’s expressive and elegant, but it can lead to subtle and costly performance issues if not used with caution. Over the years, I’ve worked on large Laravel applications where data integrity, response time, and system load were mission-critical. This post explores the common pitfalls I’ve encountered with Eloquent and how to avoid them. The N+1 Query Problem One of the most infamous issues is the N+1 query problem. If you've ever looped through a collection and accessed a relationship inside the loop, you’ve likely caused this. For example: $users = User::all(); foreach ($users as $user) { This results in 1 query to fetch users, and 1 query per user to fetch the profile — causing pote…  ( 4 min )

    BSides Seattle 2025: Rebuilding Trust in Systems In The Age Of NHIs
    Beneath Seattle's bustling Pioneer Square lies the remains of another city.

    DBSCAN: Finding Cluster of any shape
    Exploring how DBSCAN uses density, not distance, to find clusters of any shape from theory and code to real-world applications like anomaly detection and geospatial mapping. Before diving into the code or real-world applications, it’s essential to understand what DBSCAN actually is and why it stands apart from traditional clustering techniques. At its core, DBSCAN short for Density-Based Spatial Clustering of Applications with Noise is a powerful algorithm that clusters data not based on shape or center points, but on the density of data points in a region. Let’s break down the key concepts that make DBSCAN unique. Density-Based Clustering : Instead of grouping points based of distance from a center(like K-MEANS). This algorithm groups points based on how crowded a region is No need for…  ( 4 min )

    How I Lost 35kg and Built a Habit Tracker That Actually Works
    How I Lost 35kg and Built a Habit Tracker That Actually Works Six months ago, I was lazy, unfocused, and overwhelmed. I’d scroll mindlessly on my phone, work beyond healthy hours, skip workouts, and constantly put off things I knew were good for me. I didn’t need a fancy productivity system — I needed a push. Something simple. Visual. Relentless. That’s when I built Days Without – Habit Tracker. I wasn’t aiming to reinvent productivity apps. I built Days Without for myself — because I genuinely needed help. I was tired of breaking promises to myself like “I’ll start tomorrow” or “just 10 more minutes on Instagram.” I needed a streak counter. A clear, visual reminder of how long I’ve stuck to something. Something lightweight and shame-free, but still motivating. With Days Without, I start…  ( 4 min )

    Leetcode - 124. Binary Tree Maximum Path Sum
    When working with binary trees, it's common to process each node with post-order traversal (left → right → root). But when the goal is to find the maximum sum of any path, including those that may start and end at any node, we need a careful approach to handle different types of path combinations. The main idea is to use depth-first search (DFS) and, at each node, calculate: The best path that can be used to extend to the parent (choose either left or right subtree). The best complete path that can split at the current node (includes both left and right subtrees). We track a global variable res to store the maximum sum seen so far. Here’s the breakdown: For each node, recursively calculate the maximum sum path from the left and right subtrees. If a child path gives a negative sum, ignore i…  ( 8 min )

    Newborns living near trees tend to be healthier and new data suggests it’s not because healthier people reside near parks
    TL;DR: A Drexel University study dug into data from Portland, Oregon—tracking over 36,000 trees planted between 1990–2020—and found that mothers living within 100 meters of newly planted trees tend to have heavier, healthier babies. After controlling for factors like income, education and BMI, researchers saw each new tree bump birthweight by about 2.3 grams; hanging out near ten or more trees equated to a roughly 50-gram gain, plus lower risks of pre-term and small-for-gestational-age births. What’s cool is that this goes beyond just big old parks: even new saplings make a difference, hinting that planting trees is a simple, low-cost public-health win. Established trees also helped buffer road-density effects (think less noise and pollution), and the team thinks part of the benefit comes from the stress-busting “soft fascination” of green surroundings. The authors call for randomized trials, but treating tree-planting as a natural experiment already makes a strong case that more greenery = healthier starts to life.  ( 3 min )

    Does Ruby Support Tail Call Optimization (TCO) in Functional Programming?
    In functional programming, recursion is a fundamental concept often utilized to solve various problems. This leads us to the discussion of Tail Call Optimization (TCO). This optimization allows a function to call another function, or itself, without requiring a new stack frame, effectively reducing overhead and memory usage. While many functional languages utilize TCO to enhance performance, it raises an important question: does Ruby implement tail call optimization? Understanding Tail Call Optimization (TCO) TCO is key in functional programming for several reasons. When a function calls another or itself as its last action, traditional languages allocate a new stack frame for each call, which can lead to stack overflow or excessive memory use. TCO allows the programming language to reuse …  ( 4 min )

    Building a conversational AI tool for real-time analytics
    Tinybird just announced Explorations, a new conversational UI feature in Tinybird to explore and interact with your data using natural language. Instead of writing complex SQL queries or manually building dashboards, you just ask questions of your data and get answers. You type simple, natural-language questions directly into the interface. It translates your questions into contextualized SQL queries automatically. The result is displayed visually as tables and charts. Why is it useful? Data is often large, messy, and unstructured. You have to spend a lot of time studying the schema or SELECT * … LIMIT 1 to figure out its shape. Then you have to constantly check the SQL reference and iterate your queries to get things right. When data is complex, this is a huge time drain. E…  ( 7 min )
    Why I Ditched Apple Remote Desktop: A DevOps Engineer's Journey to Smarter Mac Management
    Intro: Apple Remote Desktop (ARD) might've been cool in 2010. But today, it feels like managing a modern Mac environment with a rotary phone. No logging, no alerts, clunky performance, and good luck if your team’s outside your local network. I hit a breaking point as a DevOps engineer supporting hybrid teams using Macs for testing and builds. I needed real-time access, reliable performance, and automation hooks. So I did what most of us do when we’re fed up—I built a workaround, failed at it, and then finally found a smarter way. ARD is stuck in the past. It assumes you're on the same network. It’s slow over VPN, doesn’t scale, and worst of all—it asks for manual approvals and fails silently when permissions aren’t set right.

    Programming language of the future
    The IT industry changes faster than any other industry, due to the flexibility of how information is exchanged and processed.

    SpiderJS 🕷 | JS Runtime Revealed: The Three Pillars of JavaScript Execution
    JavaScript (JS) started in browsers with Netscape, but its flexibility has spread it to servers (Node.js, Deno, Bun), mobile apps (React Native, Ionic), and desktop apps (Electron). Each environment needs a setup to run JS code and convert it to machine instructions. This setup is the JavaScript Runtime Environment. Here, we’ll explore what it is and its core components, preparing for a deeper look at JS execution in future articles. A runtime environment is the system that lets JavaScript code run and interact with its platform. It centers on a JavaScript engine, which parses, compiles, and executes code, turning JS into bytecode or machine code, often via Just-In-Time (JIT) compilation (more on that later!). But the engine isn’t enough. JS is single-threaded, handling one task at a time.…  ( 4 min )

    Llambda.co — Serverless AI made simple
    The Current Landscape 🌐 The traditional inference model, pioneered by companies like OpenAI, revolves around providers offering one or a few large language models (LLMs) with 100% uptime and swift responses. This approach simplifies GPU management since all users share the same LLM, ensuring even load distribution. However, this convenience comes at a cost: Users are typically charged based on arbitrary, non-transparent metrics like token count. The selection of LLMs is sparse, they are usually censored and your data is being trained on. 😕 An alternative is the serverless model, where you rent a GPU instance and install any LLM you want with specialization and features tailored to your needs. This approach offers: Transparency: Pay only for actual GPU usage. Flexibility: Choose from th…  ( 4 min )

    Getting my feet wet with Crossplane
    In the early days of IT, we manually configured servers–each one a precious snowflake, lovingly maintained and documented. But the size of the infrastructure grew and this approach couldn't scale. Chef and Puppet popularized the idea of Infrastructure-as-Code: engineers would define the state of the machine(s) in text files, stored in Git–hence the name. A global node would read these files to create a registry. Then, a local agent on each machine would check the desired state at regular intervals, and reconcile the current state with the registry. The first generation of IaC managed the state of existing machines but assumed the machine was already there. The migration to the Cloud created another issue: how do you create the machine in the first place? Another IaC tool appeared in the fo…  ( 7 min )

    Why Upwork Isn’t Enough Anymore. And That’s Okay
    I used to think I just needed to send more proposals. Boost the right gigs. Optimize my profile. But over time, I realized something deeper was off, not just with the platform, but with the entire freelance ecosystem. If you go to Upwork, at first, it looks like jobs are popping up all the time. Feels like opportunity, right? But most of these jobs are low-paying, low-quality, or outright spammy. It's getting disheartening. During the pandemic, I managed to land some gigs after just a couple of proposals (and I was a total noob who had just graduated). I even got a long-term client without having to pay a cent. I actually managed to land a full-time job as a PHP Developer and then I decided to focus only on it after one year. But when I came back to Upwork last year looking to make some ex…  ( 4 min )

    How to Calculate Current Onhand Inventory in Oracle SQL?
    Introduction Calculating inventory levels in SQL can be tricky, especially when you need to derive values based on previous rows. In your case, we want to compute a new column, Avail_to_fill, which will be the difference between the Onhand quantity and the Qty ordered for each item. This calculation should depend on the preceding row's result. Understanding the Problem The table you provided has several columns: ORDER#, Date, Item, Qty, Onhand, and Avl Fill. The requirement here is to create a new column that shows the available inventory (Onhand minus Qty) line by line and restarts the calculation whenever a new Item is encountered. This behavior can be achieved using Oracle SQL's analytic functions and a common table expression (CTE) for structured queries. This technique incorporates th…  ( 4 min )
    How to Start with Database Migrations
    If you're adjusting your schema or moving platforms, you're doing database migration. Whether small or large, migrations help keep your app in sync with changing requirements. This post gives you practical examples and a walkthrough of tools that simplify the process. 1.Schema Migration Change structure to support new features. Example: ALTER TABLE users ADD COLUMN last_login TIMESTAMP; Use tools like Flyway or Django ORM to track these in code. 2.Data Migration Needed when changing storage engines, consolidating databases, or upgrading versions. Example: INSERT INTO new_customers SELECT * FROM legacy_customers; Run these in batches or use a managed service for large datasets. Add indexes for speed Create constraints for safety Normalize tables for better structure Example: CREATE INDEX idx_user_email ON users(email); Flyway: Write raw SQL, versioned Liquibase: Use XML/JSON changelogs Django: Auto-migrations with Python models AWS/GCP DMS: Ideal for cloud-native migrations Updating your schema, moving data, or shifting databases entirely. Define scope, create backups, test in staging, automate changes. Not for every change, but yes for version control, rollback, and CI/CD pipelines. Loss of data integrity, broken constraints, or downtime. Avoid with dry runs and monitoring. Migrations are part of growing your application the right way. Whether adjusting models or moving cloud platforms, a structured approach with the right tools keeps your data safe. Want to discover more about data migration?

    How Code Signing Improves User Trust and Download Rates
    In today's digital landscape, software developers face a significant challenge: convincing users that their applications are safe to download and use. As cybersecurity threats continue to evolve, users have become increasingly cautious about what they install on their devices. This is where code signing emerges as a crucial practice for developers looking to build trust and increase download rates. Code signing is a security practice that involves applying a digital signature to software or executable files. This signature is an electronic proof that the code comes from a specific publisher and hasn't been tampered with since it was signed. Think of it like a wax seal on a letter in medieval times—it guaranteed the letter came from the sender and hadn't been opened along the way. Similarly…  ( 5 min )
    Shadow APIs: Understanding the Risk and 6 Ways to Reduce It
    What Is a Shadow API? A shadow API is an application programming interface that is created or used without explicit approval from the organization’s IT or security teams. Shadow APIs can emerge from various sources, including developers experimenting with new features, legacy systems that are no longer officially supported but still in use, or services integrated outside of formal IT channels. This is part of a series of articles about API security Unlike official APIs, shadow APIs lack oversight and governance, making them invisible to the security measures typically applied to known and documented APIs. They operate under the radar of standard security and monitoring practices. Because these APIs were not introduced through sanctioned processes, they are excluded from inventory or documentation efforts. As a result, shadow APIs present significant risks. They are not subjected to regular security assessments, patches, and compliance checks that would normally be part of an API’s lifecycle management in a secure software development environment.

    Azure Monitor Telemetry Client — Reinvented
    Recently, I was brought on board of yet another project to help build an enterprise-grade IT solution based on Microsoft Power Platform and Azure. Like any well-architected system, the solution required robust observability — the ability to track operational behavior, diagnose issues, and maintain visibility across all components. Naturally, Azure Monitor was the go-to choice. One of the core components of the solution was a custom plugin for Power Platform. To capture application-level telemetry from the plugin, the obvious approach was to use a telemetry client that integrates with Azure Application Insights, a feature of Azure Monitor. By default, Application Insights allows unauthenticated data ingestion — which makes it a potential target for abuse. To address this, the instance was c…  ( 6 min )

    Save Hours Managing Ghost with These Python Scripts
    I run the blog at Developer-Service.blog with a self-hosted Ghost instance. As much as I love Ghost and its editor, I've encountered a handful of limitations in the Ghost Admin interface that have slowed me down. Things like: Re-categorizing posts in bulk.

    How to Decode Nested JSON Strings in Scala with Circe?
    Introduction Handling JSON in Scala can be challenging, especially when dealing with nested JSON strings. In this article, we explore how to effectively decode a JSON object using Circe, a popular library in the Scala ecosystem. Specifically, we want to extract data from a JSON structure where one of the fields is a string that represents another JSON object. This approach is necessary to ensure that we parse and extract information correctly, allowing us to work seamlessly with complex data structures. Understanding the JSON Structure The JSON object we receive looks like this: {"key": "value", "embedded": "{\"foo\": \"bar\"}"} In this case, the embedded field is a JSON string rather than a direct JSON object.

    The AI Evolution: Why the Spotlight Has Shifted from Single Models to Multimodal Agents
    Artificial intelligence has transformed from basic chatbots spitting out text to sophisticated systems that see, hear, and reason like humans. A decade ago, AI was confined to answering simple queries; today, it analyzes images, interprets audio, and makes decisions in real time.

    How to Retrieve Selected Index from Gtk DropDown in Rust?
    In Rust, when using GTK's DropDown widget, you may want to execute a closure to retrieve the selected index upon the selection change. A common issue developers face is accessing the selected choice directly from the ParamSpec. Let's dive into how to do this effectively. Understanding the DropDown and Connect Closure When you create a DropDown in GTK, you define the choices it contains. In your example, you have created a DropDown with two options: let choix = ["Choice 1","Choice 2"]; let drop_down2 = gtk::DropDown::from_strings(&choix); Here, choix is an array containing the two options. The DropDown will display these choices in the user interface. To respond to user interaction, you set up a closure that will be executed whenever the selected choice changes. The…  ( 4 min )
    Visual Studio Code: The Unexpected Bridge Between Worlds
    In the vast universe of software development, Visual Studio Code has emerged as a key tool—an unexpected bridge connecting worlds that once seemed incompatible. It has become a lifeline for developers coming from the GNU/Linux ecosystem, desperately seeking a way to write desktop applications, something they thought was lost in their environment. Its versatility allows for development in C#, C++, and FPC Pascal, avoiding alternatives like Lazarus, and offering a more modern and robust option. Personally, I’ve found myself using it as an alternative to Visual Studio 2022, since developing a .NET 6, 7, or 8 application on Linux is financially more viable for my business than doing so on Windows. But here’s the question: Why does Visual Studio Code feel like an orphaned and underappreciated sibling compared to Visual Studio 2022? Both serve incredible purposes. Visual Studio 2022 is the enterprise-grade powerhouse, while VS Code is the agile alternative—the gateway for many developers coming from GNU/Linux, looking to explore Windows and its tools, or simply wanting to use .NET Core on Linux. That in itself is a massive achievement, a step forward in software evolution. Because in the end, bluntly speaking, Linux is great... but if it doesn’t pay the bills, what can I do? As developers, we need to produce high-quality software using high-quality tools. That’s why Visual Studio Code becomes the logical and efficient choice—a path that allows us to keep programming in diverse environments while maintaining productivity and financial sustainability. Ultimately, VS Code isn’t just a code editor… it’s the bridge that unites worlds that once seemed irreconcilable.  ( 3 min )
    VC写Windows服务程序
    之前写的后台的控制程序,我采用的都是用VC或者是C#写完之后然后采用AlwaysUp或者是nssm把自己写的后台程序再给做成一个Windows的服务程序。但后来想了想为什么不自己直接写一个Windows的服务程序呢。所以就开始了写服务程序的历程。 首先大致的说一下C#语言写一个Windwos服务程序的方法。说实话C#想写一个Windows服务程序相对的要简单的多。因为C#已经都给准备好了。就在创建项目的选择Windows服务项目就可以了。然后再添加一个服务安装的组件,改一下相关的配置,如:服务名、启动类型、启动权限或者叫启动时的用户。这些信息就可以了。在写代码的时候只要在开始的里面写上服务启动时需要做的工作,在结束里面写上服务停止时需要收尾的工作就大功告成了。 下面主要是说一下采用VC写Windows服务程序。这个我个人觉得相对来说有几个坑需要避。 第一个坑就是如果你从网上查的话都会说用VC写Windows服务程序的入口主函数是ServiceMain()这个函数。而实际并不是,实际上的程序入口还是从main()这个函数开始的。只不过在这个函数中我们不能做太多的事情,必须要尽快的调用StartServiceCtrlDispatcher()这函数来启动ServiceMain()函数。而且ServiceMain()这个函数的名字也并不一定就是这个,可以自定义。只不过你在网上查的人都会采用这个函数名而已。并非VC语言的规定或者约束。这个函数也只不过是在调用StartServiceCtrlDispatcher()函数的时候的一个参数而已叫什么名字并不重要。 第二坑就是服务状态的变换问题,只有你有ServiceMain()函数中调用了SetServiceStatus()函数来告诉Windows操作系统你的服务程序是开始启动了还时正在运行之中还是正在停止之中才可以。在这方面我从网上查了好长时间没有一个写的清楚的。我开始的时候以为这个函数没什么大用于是把相关的代码给删掉了,结果就会发生服务程序的状态无法改变。比如你在启动服务的时候没有及时的状态改成正在运行的话那么Windows的服务控制台就会一直启动这个服务直到启动超时而报错最后服务的状态就会卡在启动状态无法将服务停止或者删除。如果你能将服务状态进入到正在运行状态,但在发出停止服务的时候如果不能将服务的状修改成停止的话那么Windows也会一直停止这个服务直到停止超时而报错。而且这个服务的状态也会卡在停止的状态无法改变。 第三个坑就是在ServiceMain()函数中在用SetServiceStatus()函数把服务的状态修改成“正在运行”的状态之后必须要调用WaitForSingleObject()函数把这个服务的主线程给卡住然就是是一直等待发出服务停止的信号。所以在真正的主线程中你是无法再做其它的任何的工作的。故如果要想写好一个完整的Windwos服务程序就必须在ServiceMain()函数调用WaitForSingleObject()函数之前将你想做的事情都给加载完毕之后再调用WaitForSingleObject()函数将主线程卡住一直等待停止服务的指令。当停止服务的指令来临的时候再调用SetServiceStatus()函数把服务的状态修改成已经停止。 第四个这个不算是坑了这个算是一个常识。就是服务程序的调试问题。如果想调试Windows服务程序那么就只能采用“附加到进程”的方式。即先从Windows的服务管理器中启动服务,然后从Visual Studio的“调试”菜单中选择“附加到进程”的选项然后再选择自己程序的那个进程就可以了。 总结一下,那就是不论是VC写Windows服务程序还是C#写Windwos服务程序,都会有一个开始服务的初始化函数。而初始化函数中不能有死循环,但一般的服务程序又必须要用死循环,所以一个完整的Windwos服务程序一定是一个多线程的,在初始化的时候就启动其它的想要加载的死循环的线程。还会有一个程序的销毁函数,同样在销毁函数中也不能有无法完成的循环。最后就是Windwos服务程序的调试必须采用附加到进程的方式来进行。  ( 2 min )

    DAY 40: Array in Looping JAVA
    In Java, an array is a data structure that stores a fixed-size, sequential collection of elements of the same data type. It is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created and remains fixed throughout its lifetime. Arrays are used to organize data efficiently and can be defined and initialized in various ways. Array - Group of similar datatypes Why do you use an array? Arrays are handy when you want to work with multiple values of the same data type. Instead of declaring individual variables for each value, you can group them together in an array, making your code more concise and easier to manage.

In a May 7 filing in the US District Court for the Southern District of New York, Bond’s lawyers reiterated some of the claims Salame made in opposing his plea deal with the government, which ultimately still led to him serving time in prison. She claimed that prosecutors obtained a deal with Salame through “stealth and deception” by allegedly agreeing they would not file charges against Bond.  “Mr. Salame and Ms. Bond’s attorneys were advised that the agreement to cease investigating Ms. Bond could not be placed within the four corners of the Salame plea or other written agreem…
    Mashinsky’s 12-year sentence sets tone of enforcement in Trump era
    The US federal court for the Southern District of New York has sentenced former Celsius CEO Alex Mashinsky to 12 years in prison for fraud. Mashinsky’s legal team sought a light sentence. They highlighted his spotless record before the Celsius incident, along with his military service and willingness to plead guilty. But US prosecutors were less inclined to leniency, suggesting on April 28 that the judge deliver a 20-year sentence for his actions. Betting markets predicted a light sentence ahead of the May 8 hearing. Polymarket showed only 11% odds for a 20-year sentence or higher.

    US Stablecoin bill blocked as Democrats withdraw support
    The Guiding and Establishing National Innovation for US Stablecoins of 2025 Act, known as the GENIUS Act, failed to pass cloture in the United States Senate on May 8, dealing a slight blow to cryptocurrency regulation in the country. The bill, sponsored by Senator Bill Hagerty and co-sponsored by Senators Tim Scott, Kirsten Gillibrand, Cynthia Lummis and Angela Alsobrooks, received last-minute pushback from Democrats, who took aim at the bill and raised concerns about US President Donald Trump’s cryptocurrency ventures. To address the concerns of Senate Democrats, the bill had already been amended to include stricter requirements for stablecoin issuers for further provisions for Anti-Money Laundering. The GENIUS Act was seen as a bipartisan effort to increase regulatory clarity for digital assets in the United States. The focus of the bill, stablecoins used for payments, was looked at as extending dollar dominance internationally and straying away from more controversial crypto topics. After the procedure failed, Senate Majority Leader John Thune criticized Democrats, saying, “Democrats have been accommodated every step of the way […] frankly, I just don’t get it.” This is a developing story, and further information will be added as it becomes available.
    Trump tricked into pushing XRP for crypto reserve: Report
    US President Donald Trump was reportedly manipulated by a lobbyist tied to Ripple Labs into announcing the XRP token would be part of his plans for a national cryptocurrency reserve. According to a May 8 Politico report, an employee of pro-Trump lobbyist Brian Ballard gave the president the text to a social media post she recommended he write announcing a US strategic crypto reserve that would include XRP, Solana (SOL), and Cardano (ADA). After he posted the message to his social media platform on March 2, Trump learned Ripple was one of Ballard’s clients, infuriating the president, who felt like he’d been used, Politico reported, citing two people familiar with the incident. “He is not welcome in anything anymore,” said Trump, referencing Ballard, according to the report.

    SEC considers new rules easing security token issuance
    The US Securities and Exchange Commission (SEC) is considering rule changes to let companies more freely issue tokenized securities, SEC Commissioner Hester Peirce said in a speech published on May 8. The regulator is “considering a potential exemptive order” for firms using blockchain technology to “issue, trade, and settle securities” that would release them from certain registration requirements, Peirce said in the speech. For example, decentralized exchanges (DEXs) may no longer need to register “as a broker-dealer, clearing agency, or an exchange,” Peirce said. The SEC has previously brought numerous charges against DEXs such as Uniswap for failing to register as securities exchanges. Firms should “not have to comply with inapt regulations, which, in many cases, were developed well b…
    Are layer 2s good for Ethereum, or are they ‘extractive?’
    Layer 2s have been a great blockchain success story. They’ve reduced congestion on the Ethereum mainnet, driving down gas fees while preserving security. But maybe they’ve become too successful, drawing chain activity and fee income from the parent that spawned them? At least that’s what some are suggesting lately, most recently at Cornell Tech’s blockchain conference in late April. Indeed, some think Ethereum should be a little greedier, or at least fight harder for a bigger part of the revenue pie, particularly sequencing fees.  “People in the Ethereum Foundation [the nonprofit that supports the Ethereum ecosystem] will tell you that, ‘Yes, we effed up by being too ivory tower.’ I have heard that multiple times,” said David Hoffman, an owner at Bankless, during a panel discussion at the …

    Ex-Celsius CEO asks to travel for a wedding after sentencing
    Former Celsius CEO Alex Mashinsky will probably be allowed to travel for his daughter’s wedding regardless of the outcome of his May 8 sentencing hearing. In a May 8 filing in the US District Court for the Southern District of New York, Judge John Koeltl approved an application for Mashinsky to travel from New York to Memphis, Tennessee, between May 26 and May 29 for his daughter’s wedding. The approval was available on the public docket on May 8, but later appeared to have been removed. Judge Koeltl will determine in a May 8 hearing whether Mashinsky serves prison time following a plea deal with prosecutors. The former Celsius CEO appeared ready to go to trial in 2024 until his lawyers lost a motion to have his charges dismissed. He pleaded guilty to commodities fraud and a fraudulent scheme to manipulate the price of the platform’s native token, CEL. Mashinsky has been free on a $40-million bond since July 2023, with travel outside certain areas requiring court approval, such as the roughly 900-mile (1,500-kilometer) distance between New York and Memphis. As of May 8, it’s unclear if he will be expected to surrender to authorities.

    User experience could be crypto’s superpower—or its kryptonite
    Opinion by Jonathan Farnell, CEO of Freedx It’s 2025, and over 560 million people worldwide are already using cryptocurrency — roughly 17 times the population of Tokyo. That’s a vibrant community, yet for every user who’s embraced it, billions more stand on the sidelines, put off by the complicated interactions and clunky interfaces of protocols, platforms, decentralized apps (DApps), and mobile applications. Why? Blockchain technology offers game-changing potential — decentralized ownership, secure trades — but let’s face it: Most people still find it intimidating, risky, and confusing. User experience (UX) might just be the deciding factor in whether cryptocurrency achieves mass adoption or remains a niche segment. Take complexity. A 2024 Chainalysis report pointed out that 43% of would-…

    Beyond digital gold, Bitcoin’s next chapter is about to be unlocked — Dan Held
    Bitcoin (BTC) has long been branded as “digital gold,” a store of value for believers in scarcity, decentralization and self-sovereignty. As institutional interest grows, geopolitics shift, and new layers emerge on Bitcoin’s stack, is it time for the narrative to evolve?  In this episode of The Clear Crypto Podcast, hosts Nathan Jeffay and Gareth Jenkinson speak with longtime Bitcoiner and entrepreneur Dan Held, who argues that Bitcoin’s next chapter may unlock broader functionality, from programmable use cases to more nuanced messaging that reaches far beyond crypto-native circles.

    Coinbase to acquire options trading platform Deribit for $2.9B
    Coinbase, the largest cryptocurrency exchange in the US by trading volume, has agreed to acquire Deribit, one of the world’s biggest crypto derivatives trading platforms. Coinbase Global will acquire Deribit for about $2.9 billion, the exchange announced on May 8. The acquisition will allow Coinbase to expand into the profitable crypto derivatives market and continue scaling the platform’s global growth, Greg Tusar, Coinbase’s vice president of institutional product, said in the announcement. “With Deribit’s strong presence and professional client base, Coinbase is making its most substantial move yet to accelerate our international growth strategy,” he said. Source: Coinbase Deal follows reports of Dubai regulatory steps The $2.9 billion deal includes $700 million in cash and 11 million shares of Coinbase Class A common stock, subject to customary purchase price adjustments. “This transaction is subject to regulatory approvals and other customary closing conditions and is expected to close by year-end,” the announcement said. Previous reports in March suggested that Coinbase and Deribit had alerted regulators in Dubai about the potential deal, as Deribit holds a license in Dubai, which would need to be transferred to Coinbase if the deal is successful. The reports also previously suggested that a deal with Coinbase could value Deribit at between $4 billion and $5 billion.

    Browser-based crypto mining in 2025: Still viable or virtually dead?
    Key takeaways After the shutdown of Coinhive in 2019, browser mining has made a comeback with new tools like CryptoTab Browser, Pi Network and YouHolder. Mining with a browser can cost more in electricity than the crypto earned, especially for users with mid-range devices. Despite being less energy-intensive than ASIC farms, browser mining still adds up in terms of cumulative power draw and puts a strain on your device’s hardware. Browser mining is evolving with the help of WebAssembly (Wasm), improving script efficiency and creating a smoother user experience.  Browser-based crypto mining sounds like a dream: Just open a webpage, let it run, and your computer starts earning crypto in the background.

    Bitcoin DeFi sees surge in mining participation despite drop in TVL
    Smart contract platform Rootstock, the home of decentralized finance (DeFi) on Bitcoin, saw a sharp increase in network security and mining engagement in the first quarter of 2025, even as activity cooled. Merged mining participation surged to an all-time high of 81%, up from 56.4% in Q4 2024, driven by the integration of major mining pools Foundry and SpiderPool, according to Messari’s first “State of Rootstock” report for 2025, shared with Cointelegraph. The heightened miner interest boosted Rootstock’s hash power to over 740 exahashes per second, surpassing the total Bitcoin network hashrate recorded in October 2024. As a result, the network is now considered to be in a “mature phase” of merged mining growth. The increased security coincided with a 60% reduction in transaction fees, imp…

    Static Method
    Static method is a method bound to class and not the object of class. To define static method we will use @staticmethod decorator. Explanation: If you want somebody not to access specific function through object you can do it by applying the @staticmethod. And do not pass 'self' because it will create connection with other attribute. But if you seen closely general_description is accessible through object and class also. So the question arises does this statement defy us. Well answer is, Yes, it does. Here is analogy: You will kept your screwdriver, hammer or nickel in toolbox, so that somebody want to access it he/she will look for toolbox. If you travel through airplane doesn't which model of airplane you travel the manual of that plane will remain same like how to tie seatbelt. Same as goes for static method you just access static method function through class not by object and it doesn't defy its meaning. OOPs concept is philosophical you follow the rule so that you can have strategy how write code effectively.  ( 3 min )
    AI could do a lot more than just note-taking in meetings
    Why do we limit AI to just note-takers in meetings? Sure, summarization is useful, but there's so much more AI could do to improve our discussions. What if AI could help surface those important questions that often get missed? Or guide teams to explore angles they haven't considered? That's where the real value lies - improving the conversation, not just documenting it. It's simple really - teams don't need another tool for meeting minutes. They need help having better conversations that lead to clearer decisions. The future of meeting AI isn't in better note-taking. It's helping teams have discussions that matter.

    How to Prevent CSS Hover State Flicker on Button Release?
    Introduction When styling buttons with CSS, achieving a seamless hover effect is crucial for a great user experience. The problem arises when you have a hover effect that causes a noticeable flicker when you release the mouse button.

The flickering effect you noticed is common when using CSS transitions for hover states.

    Implicit Index Access in C# 13 — Using `^` in Object Initializers
    ^ in Object Initializers The ^ operator (read as "from the end") has been part of C# since version 8, allowing developers to easily access elements from the end of collections: int last = myArray[^1]; // Last element However, until C# 13, you couldn’t use ^ inside object initializers. This restriction has now been lifted, giving developers more expressive and compact ways to initialize collections directly. Let’s explore how this change improves array initialization syntax and simplifies common patterns. Prior to C# 13: var countdown = new TimerRemaining(); countdown.buffer[^1] = 0; // Valid But you could not write: var countdown = new TimerRemaining { buffer = { [^1] = 0 } // ❌ Compiler error before C# 13 }; Now, this syntax is fully supported. ^ in Initializers public class…  ( 4 min )

But in 2025, it’s clear: I recently made a quick YouTube Short that summarizes this shift in just 60 seconds. But I wanted to share a bit more context with the dev.to community, because many of us are building this future. Here’s what’s really changing: AI handles what used to be the boring, manual work, form filling, task assignment, ticket tagging, report generation. Not only is it faster, but it actually lets teams focus on solving real problems. AI isn’t just reacting anymore, it’s learning. We’re seeing apps that adjust to each user: what they click, when they drop off, which features they ignore. AI then reshapes the experience in real time. Feels like magic (but it's models). Whether it’s predicting churn, forecasting demand, or recommending next steps, smart SaaS tools are becoming proactive. This gives users (and product teams) a serious advantage. At ClickIT, we’ve been working with startups and mid-size companies to integrate this kind of AI into their SaaS platforms. It’s wild how quickly things evolve once AI becomes part of your architecture, especially when the goal is to scale fast without losing control. Here’s the video I mentioned, just 60 seconds, made to spark ideas: How AI Is Revolutionizing SaaS in 2025 Are you already integrating AI into your product? If not ❌ — What’s holding you back? And if yes ✅ — What has surprised you the most? Would love to hear how other devs, founders, and engineers here are approaching the AI shift in SaaS.  ( 3 min )
    How to Debug TypeScript with Node.js and VSCode Correctly?
    Debugging TypeScript code in Node.js projects can sometimes lead to frustrating experiences, especially when working with multiple projects that have dependencies on each other. If you're encountering issues where VSCode's debugger steps into a temporary compiled JavaScript source instead of the original TypeScript files when debugging your project Foo, you've come to the right place. Let's address the common issues and provide you with clear solutions for setting up your debugging environment effectively. Understanding the Problem When you create a dependency between two Node.js projects, like Foo and Bar in this case, you might run into trouble with your breakpoints not being recognized. The debugger might often navigate through transpiled JavaScript files, making it challenging to debug…  ( 4 min )

    Implementing xor value swap without third variable in C
    Swapping variables is one of the most basic procedures that are done in programming. The first approach -and usually the most used by far- is to swap using a third variable, commonly named temporal variable. I'm sure you have seen it already. void swap(int* a, int* b) { int temp = *b *b = *a *a = temp } Yeah, that's a lot of pointers for explaining a swap. Blame C, not me 😒. Either way the process is the same in all languages: The value of variable b is stored in a temporal variable The value of variable a is stored in b The value stored in the temporal variable is moved to a I don't think it is necessary to say that the same process can be done replacing a with b and b with a But what if I told you that there's a way to swap values without using extra memory for a third vari…  ( 5 min )

    What is Data Remanence?
    Data Remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously written data to be recovered. Data remanence may make inadvertent disclosure of sensitive information possible should the storage media be released into an uncontrolled environment (e.g., thrown in the bin (trash) or lost). Various techniques have been developed to counter data remanence. These techniques are classified as clearing, purging/sanitizing, or destruction. Specific methods include overwriti…  ( 3 min )

    Under the hood: What can you learn by building an HTTP Server from scratch?

Most of the time, we don't think much about it since HTTP has been around for a long time, and there are thousands of HTTP servers and clients, so most people don't give much thought to how these technologies work! As someone who worked on many web-based applications and built many restful APIs, I would like to think that I have a pretty good understanding of how the HTTP protocol works and how HTTP servers generally function, however, since I've always been using ready-made HTTP servers (Mostly Kesterl, IIS and Nginx) and HTTP clients (curl, postman, httpie) I felt that there's a lot that I can learn …  ( 14 min )

    Matrix in Python
    Problem 1: Check for a Toeplitz Matrix Problem: You are given an n x n square matrix. Write a function is_toeplitz(matrix) that checks whether the matrix is a Toeplitz matrix. A Toeplitz matrix is one where every descending diagonal from top-left to bottom-right (↘️) contains the same elements. Consider this matrix: 6 7 8 4 6 7 1 4 6 The diagonals are: [1], [4, 4], [6, 6, 6], [7, 7], [8] All elements in each diagonal are equal — so this is a Toeplitz matrix ✅. To check if a matrix is Toeplitz: Loop through each element in the matrix (excluding the last row and column). For each element, compare it with the one diagonally down-right from it. If any of those pairs don’t match, return False. If the loop completes without mismatches, return True. from typing import List def is_toeplitz(matrix: List[List[int]]) -> bool: n = len(matrix) for i in range(n): for j in range(n): if i + 1 < n and j + 1 < n: if matrix[i][j] != matrix[i + 1][j + 1]: return False return True matrix = [ [6, 7, 8], [4, 6, 7], [1, 4, 6] ] print(is_toeplitz(matrix)) # Output: True  ( 3 min )
    Famed AI researcher launches controversial startup to replace all human workers everywhere

    #7 DP: Observer
    O que é o Padrão Observer? O Observer é um padrão de projeto comportamental que define uma relação de dependência entre objetos, onde um objeto (o sujeito) notifica automaticamente outros objetos (os observadores) sempre que seu estado muda. Ele é muito útil quando várias partes do sistema precisam reagir a mudanças em um mesmo ponto. Esse padrão promove o desacoplamento entre quem emite o evento e quem reage a ele, permitindo que novos observadores sejam adicionados ou removidos em tempo de execução, sem alterar o sujeito. Em resumo, o Observer estabelece um mecanismo de notificação automática, garantindo que todos os interessados estejam atualizados sempre que algo importante acontece. As classes que devem reagir a mudanças se inscrevem no sujeito responsável por emitir essas mudanças. A classe principal recebe os observadores via o método addObserver(), registrando as implementações interessadas em ser notificadas. O método newStockData() executa a ação principal e, em seguida, notifica todos os observadores inscritos, permitindo que eles executem suas responsabilidades de forma independente. Assim caso surja uma demanda de adicionar uma nova açãoao newStockData, você não precisaria modificar a classe  ( 3 min )

    Regular Expression
    I had read about regular expressions and thought of writing a blog on this. I will try to cover as much as possible. Let's start with the basic definition. A regular expression (also “regexp”, or just “reg”) consists of a pattern and optional flags. In short, it is the method of matching strings to a pattern. Two syntaxes can be used to create a regular expression. const regexp = new RegExp("pattern","flags"); OR const regexp = /pattern/; //without flags const regexp = /pattern/flags; Regex should be written within forward-slashes /..../. These slashes play the same role as quotes in strings. The main difference between the syntaxes is that when the regular expression remains constant, use a pattern with a slash for better performance, but if the regular expression is changing, or you d…  ( 4 min )

    Mastering Functional Programming: Immutability, Composition, Pure and Arrow Functions
    Functional programming has gained traction in modern development due to its ability to produce more predictable, modular, and testable code.

    For over 15 years, the smartphone has been the centre of our digital universe. It’s the screen we stare at, the tool we work on, the device we reach for instinctively. But look a little closer — and you’ll start to see the shift. We’re entering the post-smartphone era. Not with a bang, but through quiet disruption. And it’s already on your body. The Rise of the Wearable Web I wear a smartwatch that tracks my health, receives notifications, and lets me respond instantly. Samsung just launched a smart ring — one more layer of ambient computing wrapped around our daily lives. And of course, I can speak to an AI assistant and get intelligent, contextual responses without touching a screen. This is no longer sci-fi — this is now. A New Hub: The Invisible Puck Imagine: A tiny 5G/6G puck lives in your backpack Your glasses are your screen Your ring is your security token Your watch handles notifications and health Voice becomes your primary interface AI becomes your operating system No more swiping. No more “app folders”. No more trying to type with your thumb while walking. Screens Are Becoming Optional Even today, I can ask my glasses to play a song, call someone, or answer a question — all without touching a smartphone. I don’t need a “phone” to live connected. I just need smart inputs, wearable endpoints, and a cloud intelligence layer. What This Means App developers will have to rethink interaction: conversational, contextual, multi-device. Privacy, identity, and edge computing will take centre stage — because the phone as a walled garden will be gone. We’ll be more present — or at least, less distracted by rectangles. The Debate Begins Will we embrace ambient computing — or push back against losing physical control? One thing’s clear: the era of staring at your hand all day is giving way to something new. So here’s the question: Would you give up your phone if you could wear the web instead?  ( 4 min )
    How to Fix the 'Error when checking target' in TensorFlow.js
    When working with TensorFlow.js, it's not uncommon to encounter errors related to tensor dimensions. One such error, as you've described, occurs when the expected dimensions of your model's output do not match the shape of the provided labels (targets) during training. Let's explore this issue further and provide solutions to resolve it. Understanding the Error The error message you received states: Error when checking target: expected dense_Dense2 to have 2 dimension(s) but got array with shape 2,5,2. This indicates that the output layer of your model was expecting a different shape for its targets than what it received. In simpler terms, the model's structure is out of sync with your training data's shape. Why This Happens In your model, the last dense layer is configured to output a 5-d…  ( 5 min )

    How I Connected My Home Network with AWS Regions Using Tailscale and VPC Peering
    Hey there, fellow tech tinkerers! As a developer and cloud enthusiast, I love messing around in my home lab—a trusty Raspberry Pi 5 running my self-hosted setup. But sometimes, I need to tap into the power of AWS for testing, dev work, or hybrid projects. In this post, I’m spilling the beans on how I bridged my home network with two AWS regions (ap-south-1 and us-east-1) using Tailscale, EC2, and VPC Peering. The result? A secure, low-latency network that feels like magic. Let’s dive in! My home lab is my sandbox for coding, experimenting, and breaking things (gently). But when I need AWS’s managed services—like serverless functions or storage—I don’t want to deal with public IPs or clunky SSH setups. My goal was to create a private, secure, and dead-simple network bridge connecting: My Ho…  ( 5 min )
    Thought 20250507 What is MCP
    There is a lot of noise on "MCP (Model Context Protocol)" and as someone at the forefront of technology we have no choice but to follow it up. Often, despite the initial waryneess the AI hype drains my energy, some careful study turns out to generate useful insights. MCP is a protocol, but the majority of the protocol work is already done when OpenAI annouced tool use for ChatGPT. What matters now is the standardization process of the publisher of MCP, i.e. Anthropic (Creator of Claude models and tools). In addition to the publications, MCP offers server/client implementations for C#, Python, JavaScript - and that can speed up and streamline the development process. Whenever an experienced developers sees the tool use API (e.g. from OpenAI), they will immediately think of automatic code generation and streamline and tool definition process, and develop custom tooling to define those tools and serve those tools. MCP offers a ready-to-use (language-of-your-choice) implementation for a stated server. But here is a critical observation: does MCP has anything to do with AI/LLM at all? It's reinforcing what should have already been done: making systems reflective and accessible from an outside system. Here is a pun: it requires existing systems to be more reasonable (also see Forbes article on GEO). Traditionally, when a software is developed if the original developer doesn't expose useful APIs then power users have no obvious way of automating it, except through the more hacky GUI automation route. Now with the pressure of AI, vendors have to expose useful interface. LLM with its natural language nature makes it easiser for them to pick, compared to picking a more specific scripting language (or rest API), especially when the MCP server/client framework is stated and uses JsonRPC. Also see: Medium post on "Some Reflections on MCP".  ( 3 min )
    What is TDD and BDD? Which is better?
    TDD and BDD Explained TDD = Test-Driven Development BDD = Behavior-Driven Development BDD is all about the following mindset: Do not test code. Test behavior. So it's a shift of the testing mindset. This is why in BDD, we also introduced new terms: Test suites become specifications, Test cases become scenarios, We don't test code, we verify behavior. Let's make this clear by an example. If you are not familiar with Java, look in the repo files for other languages (I've added: Java, Python, JavaScript, C#, Ruby, Go). public class UsernameValidator { public boolean isValid(String username) { if (isTooShort(username)) { return false; } if (isTooLong(username)) { return false; } if (containsIllegalChars(username)) { …  ( 6 min )

    Is the Behavior of std::byte in C++17 a Bug or Intended?
    Introduction In my journey through C++17, I stumbled upon the std::byte type and discovered some perplexing behavior that left me scratching my head. The main question is whether this behavior is intended by the C++ standards or if it's a quirk due to the compiler or operating system I am using. Understanding std::byte The std::byte type introduced in C++17 is designed to encapsulate the idea of a byte without its conventional mathematical interpretations. Unlike integers, std::byte doesn't implicitly convert to numeric types, which can lead to some interesting outcomes when performing operations with it. In the example I encountered, I defined a std::byte variable and used std::to_integer to convert it to different integer types. The Code Example Here’s the code snippet that raised my que…  ( 5 min )

    What is an HTTP Proxy?
    Ever wondered what keeps your online experience smooth, secure, and sometimes even anonymous? Meet the HTTP proxy — a powerful intermediary that stands between your device and the internet. At its core, an HTTP proxy processes and forwards your HTTP requests, essentially acting as a gateway. Instead of your browser connecting directly to a website, the proxy server does the job on your behalf, masking your IP address and offering a range of added benefits. To really grasp what an HTTP proxy does, you need to understand its building blocks. Hypertext Transfer Protocol (HTTP) is the standard protocol for transferring data online — everything from browsing websites to interacting with web applications. While HTTP operates over TCP/IP and Google's QUIC protocol, it lacks built-in encryption. I…  ( 5 min )

    Does a Function Call End the Lifetime of Variable Length Arrays in C?
    When dealing with variable length arrays (VLAs) in C, a common concern arises regarding the lifetime of such arrays when a function call is made after their declaration. According to the C17 final draft document N2176, the lifetime of an object, including a VLA, extends from its declaration until the program execution leaves the scope of that declaration. This statement often leads to questions about whether calling a function immediately after declaring a VLA results in ending its lifetime. To clarify, let's first understand what a variable length array is and its properties. A VLA is a type of array in C where the size is determined at runtime rather than at compile-time. This feature makes VLAs quite flexible for situations where the size of data is not known until the program runs. Und…  ( 5 min )

    If we haven't met yet, I am Aditya Bhattad—and I am here to build!
    Back in 2016, when cheap internet suddenly became available across India, I saw firsthand how technology changed everything around me. From Instagram to YouTube, these platforms completely changed how we connected with people and learned new things. Something clicked for me back then – I wanted to be part of creating this kind of change, not just watching it happen. So, four years later in 2020, when I had to pick my major stream for graduation, Computer Science was a clear choice, As I look back, it was absolutely the best decision I have made.

    Binary Tree in Rust
    I am not new to rust. I have dabbled in axum, tonic, bevy and ratatui for some personal and work projects as well. Even then when someone asked me to write a Binary Search Tree(BST) in rust, I got scared. I didn't express this at the time but it kept bugging me inside. Anyway later on whenever I used to get time I used to ask AI tools to help me teach rust and write a BST specifically. I used Gemini and ChatGPT and both gave solutions as well. I could understand their code but still couldn't understand how they got there. They used Rc, RefCell etc. which I understand theoretically but never understood when and how to use it properly. After I didn't feel satisfied using AI answers I thought let me just read code. Rust actually provides a BST in standard library, you can find it here. Its ve…  ( 5 min )

    Create a simple REST application using Quarkus
    This tutorial was originally published on IBM Developer by Markus Eisele Quarkus is a Kubernetes-native Java stack tailored for GraalVM and OpenJDK HotSpot. Quarkus offers incredibly fast boot times, low RSS memory consumption, and a fantastic developer experience with features like live coding. This quick start guide gets you up and running with Quarkus on macOS, including necessary tools. You will build a basic database application using Quarkus, Java 17, PostgreSQL, and Hibernate ORM Panache. While Hibernate ORM is the standard, powerful Jakarta Persistence implementation capable of complex mappings, it doesn't always make the most common tasks trivial. Hibernate ORM with Panache is Quarkus's solution to this, focusing specifically on making your data entities and repositories simple, straightforward, and fun to write by reducing boilerplate code for common persistence operations. We'll use standard macOS tools and package managers where possible. These are the essential tools you'll need to complete this tutorial: - Podman - SDKMAN - Java 17 - Quarkus CLI - Maven Optionally, you can also install a code editor. Quarkus integrates seamlessly with containers, especially for development services like databases and other sytems. Podman is a daemonless container engine alternative to Docker. On Mac, each Podman machine is backed by a virtual machine. Once installed, the podman command can be run directly from the Unix shell in Terminal, where it remotely communicates with the podman service running in the Machine VM. It is almost transparent in usage to Docker and easy to use for development. Install Podman. Find the latest Podman release on the GitHub Release page, and download the binary for your system architecture. At the time of writing, the latest release was v5.4.1. Install either the unversal pkg installer or the arm or amd version. Continue reading on IBM Developer  ( 3 min )

    🔐 How to Secure Your AWS Lambda Functions in 2025
    AWS Lambda is a go-to service for building scalable, event-driven applications — but with great (serverless) power comes great responsibility. Here are some practical security best practices to keep your Lambda functions secure in 2025: ✅ 1. Use the Principle of Least Privilege Create dedicated IAM roles for each Lambda function. Grant only the permissions required for that function to operate. Use IAM policies with explicit allow/deny for tighter control. 🔐 2. Secure Environment Variables Instead: Use AWS Secrets Manager or SSM Parameter Store to securely manage credentials, API keys, and tokens. Access them during function runtime using IAM roles. 🌐 3. VPC Integration for Sensitive Resources Place it inside a VPC for better network isolation. Use private subnets with minimal internet exposure. Attach VPC endpoints for secure AWS service access. 📊 4. Monitor and Log Everything Amazon CloudWatch Logs for tracking function output and errors. CloudWatch Metrics to monitor: Invocation counts Duration Throttles and errors Optionally, integrate with AWS X-Ray for tracing. 📦 5. Enable Versioning and Aliases Use Lambda versioning to avoid overwriting stable code. Use aliases (like dev, prod) to route traffic between versions easily. Helps in rollbacks and gradual deployments. 🚀 Get Started Start applying these best practices today to make your AWS Lambda functions secure, resilient, and production-ready in 2025.  ( 3 min )

    Keep on Mocking with a Key, Girrrrl
    (with apologies to Neil Young) tl;dr - a story is told about how the author tests a module against a third-party web API when that service is not always available and without leaking sensitive authentication tokens You find yourself to be an aspiring CPAN author of a web API and as a righteous follower of Test Driven Development you want to write tests to verify that your API works as advertised. Testing is a big part of Perl culture, so a skeleton module usually comes with a t/ directory to hold your tests. Once uploaded to CPAN, the CPAN Testing Service will run your tests on every OS and version of Perl possible, but you shouldn't require an active network connection on either end. After all, has your API failed because the end service is down for annual maintenance or the local interne…  ( 5 min )
    How to Fix Google OAuth Error 403 User Agent Issue on iPhone?
    Introduction When integrating Google OAuth for authentication in your application, you might encounter various errors. One common issue is the ERROR 403: Google disallowed user agent, especially if your code works perfectly on Android but fails on iPhone. This error message usually indicates that Google is rejecting the request due to the user agent string that your app is sending. Let's explore why this happens and how to fix it. Understanding the Issue The ERROR 403: Google disallowed user agent typically occurs when Google’s servers identify an untrusted or unsupported user agent accessing their OAuth service.

    Why I Prefer Go Over Node.js for Backend Development
    As a softwar developer, choosing the right language and tools can make a huge difference in how efficiently you build, maintain, and scale applications. While Node.js is widely adopted in the backend world, I personally prefer Go (Golang) for several key reasons. Here's why. Go is a compiled language with built-in support for concurrency through goroutines and channels. Whether it's handling multiple HTTP requests or processing data-heavy tasks, Go offers consistent and high performance with minimal memory overhead. Its lightweight concurrency model is often simpler and more efficient than JavaScript’s event loop and async/await system. Go is statically typed, which helps catch errors early during compilation. In my experience, this leads to more robust code and reduces the kind of silent …  ( 4 min )
    Delta Executor: Mobile-First Roblox Script Execution
    How We Built Delta Executor: Mobile-First Roblox Script Execution Roblox's scripting ecosystem has exploded in recent years — and so has the need for tools that empower developers to understand, test, and interact with Lua-based environments. At DeltaDevs, we created Delta Executor, a performance-first, cross-platform executor tailored for Roblox scripts on Android and iOS. Many tools in the Roblox ecosystem are outdated, unsupported, or overly complex for mobile users. Delta Executor solves that with: Script execution that’s stable across devices A secure framework with memory-safe design Keyless access for paid users (and fair key-based access for free users) Smooth compatibility across Android, iOS, and emulators for PC We built it from the ground up to handle the latest anti-cheat systems Roblox introduced in 2025. Here’s how we bypassed them. -- Delta Executor Example print("Hello from Delta Executor on Mobile!") You can load, run, and debug scripts just like this on mobile devices using our tool. Full support for popular script libraries and obfuscation is built in. While built for mobile-first use, Delta Executor also runs on Windows using emulators like BlueStacks or LDPlayer. Want to see how it works? Visit our Executor Overview Page. We're also opening up SDK access for vetted contributors and curious reverse engineers. Apply at deltadevs.net/developers We built Delta Executor with security transparency at the core. If you've seen antivirus warnings, you're not alone — many executors trigger false positives. Here's why. Official Website FAQs Script Submission Fix Guide: Executor Not Opening Delta Executor is more than an exploit tool — it’s a research sandbox for scripters, hobbyists, and curious minds working within the Roblox engine. We hope this adds value to others building tools around Lua, mobile execution environments, and anti-cheat resistance. Got thoughts? Drop your feedback or reach us via our Discord.  ( 3 min )
    When “More” Isn’t Better — A Note from a Senior Engineering Manager
    In tech, we’re wired for growth—more velocity, more releases, more impact, more headcount. But lately, I’ve been asking myself: Where does it stop? I’ve led high-performing teams, shipped at scale, climbed the ladder. But with each new role, I noticed a pattern—what looked like “success” on paper often came with hidden trade-offs: less time with family, more stress, fewer pauses to reflect. We’re told to aim for the next title, the bigger compensation package, the unicorn IPO—as if each step up will quiet the internal noise. But it doesn’t. Even at the top, many feel like they’re still chasing something just out of reach. And here’s the kicker: when wealth and power concentrate, whether in tech or society, others get squeezed. I’ve seen brilliant engineers burn out, not because they weren’t good enough—but because the system kept telling them they had to want more. But what if the real clarity doesn’t come from achieving more—but from needing less? Less chaos. I’ve found meaning in simpler things—mentoring a junior dev, walking outside between meetings, unplugging for dinner with my kids. These aren’t productivity hacks. They’re sanity savers. Because underneath the frameworks and sprint goals, we’re just part of something bigger—organic, changing, deeply human. The atoms in our bodies? They were once stars. Literally. We are nature. And like nature, we’re not meant to scale infinitely. So here’s a quiet question I’m sitting with—and maybe you should, too: 🔍 Is your pursuit of “more” giving you peace—or quietly taking it away?  ( 3 min )
    SafeLine WAF Setup: How to Handle Multiple Apps on Port 80
    📍 Problem description You have two applications: App 1 → deployed on Server A, port 80 App 2 → deployed on Server B, port 80 When you try to configure both behind SafeLine WAF, you get the error: Duplicate applications detected on port 80: * The reason for this error is: SafeLine allows only one listener on port 80 on the frontend. ⸻ ✅ How to solve it Since SafeLine currently does not support path-based routing, the only supported solution is domain-based routing. ⸻ Use different domain names (recommended) For example: App 1 → app1.example.com → Server A:80 App 2 → app2.example.com → Server B:80 In SafeLine: Configure one listener on port 80 Set routing rules based on the Host header (domain name) to forward traffic to the correct backend server. This way, SafeLine knows exactly which application the request is meant for. ⸻ ⚠️ Why you can’t use multiple port 80 listeners or path-based routing SafeLine can only bind to port 80 once on the frontend. Multiple port 80 listeners will always result in a duplicate port error. Path-based routing (/app1, /app2) is currently not supported in SafeLine. ⸻ 🚀 Summary recommendation ✅ Use different domain names and set up Host-based routing in SafeLine. ⸻ SafeLine Website: https://ly.safepoint.cloud/ShZAy9x https://github.com/chaitin/SafeLine https://discord.gg/dy3JT7dkmY  ( 3 min )
    How to quickly transform multi-layer sets in JSON strings
    There is a 2-layer JSON string with multiple dynamic key values in the lower layer, excluding set/array types. {"Games": {"key1": "value1", "key2": value2,"key3":value3}} Now we need to transform the lower layer into a set of multiple layers. {"Games":{"AllGames":[{"key1":["value1"]},{"key2":["value2"]},{"key3":["value3"]}]}} SQL itself does not support multi-layer data, making it more difficult to express multi-layer sets, and the indirectly implemented code is very complex. SPL naturally supports multi-layer data and multi-layer sets: Try.DEMO A2: Take the lower-layer data (one record), change the type to a set of records, and then transpose it to a two-layer sequence. […] represents a set, function E can convert a set of records into a two-dimensional sequence, and @ p represents transposition during conversion. new(new(…:AllGames):Games) Add two layers of record types on top of a multi-layer set to construct the target table sequence. esProc is free.

    Part 3: Mastering SafeLine WAF – Testing, Docker Setup & Troubleshooting
    Welcome to the final part of our SafeLine WAF series! So far, you have set up SafeLine and configured it for your environment. Now, it’s time to test your protection, finalize your Docker installation if necessary, and troubleshoot any issues that may arise. This will help you maintain a robust and reliable WAF deployment. You can test the protection effectiveness either manually or automatically. Access your website using the parameters configured in SafeLine WAF: Open your browser and visit: http://: / The default protocol is HTTP; check the SSL option to use HTTPS. The hostname can be either the SafeLine IP or your website domain (make sure the domain resolves to SafeLine). The port is the one you configured in SafeLine for the site. If your website is not accessible, please refer to the Configuration Issues section. Try these URLs to simulate attacks and confirm SafeLine blocks them: SQL Injection: http://: /?id=1%20AND%201=1 XSS Attack: http://: /?html=alert(1) If SafeLine blocks these, you’ll see the attack prevented in your browser and logged in the dashboard. ✅ sudo yum update If you get errors like “Could not resolve host” or mirrorlist failures, add Alibaba Cloud repo: curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo sudo yum install -y yum-utils sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo sudo yum -y install docker-ce docker-ce-cli containerd.io sudo systemctl start docker If you get x509 certificate errors when pulling images, it’s likely a system time or certificate issue.

    Check Docker Installation Details- Part 2
    Now that we've confirmed Docker is installed and running (Part 1), let's test the setup by running a simple container. This will verify that Docker can successfully download images and run containers. The Hello World Container Docker offers a lightweight "hello-world" image specifically designed to test Docker installations. This minimal container confirms that: • The Docker client can connect to the Docker daemon. 1.Let's run this test container with the following command: docker run hello-world • Check if the hello-world image exists locally This message confirms that your Docker installation is working correctly. After running the hello-world container, let's check the list of containers on your system. The container we just ran has already exited, but we can still see it in the list of all containers. 2.To see all containers (including stopped ones), run: docker ps -a The -a flag shows all containers, including those that have stopped. Without this flag, docker ps would only show running containers. STATUS column shows "Exited (0)", which means the container completed its task and exited with a status code of 0 (indicating success). The hello-world image was downloaded to your local machine. Let's verify this by listing all Docker images: docker images This confirms that the hello-world image is stored locally on your system.

    Paraglide 2.0 Migration – From Framework Glue to Clean Abstraction
    From time to time, it's necessary to bring all dependencies up to date. Most of them update easily. Paraglide.js? Definitely not. This post is not just a dry migration guide — it’s also about the headaches, surprises, and a few decisions you’ll have to make if you’re already deep into a SvelteKit project like I am with shrtn.io. And while we’re at it: Paraglide’s approach to minimalism still makes me smile — even if it makes the docs a bit too... minimal at times. That said, version 2.0 is a huge step forward. The documentation is better, the architecture is more maintainable, and the framework independence finally feels real.

    How to Build a Bulletproof QA Process
    In today's fast-paced tech world, speed matters. But quality matters even more. No one wants to launch a product full of bugs or deliver a user experience that doesn't live up to expectations. That's where quality assurance (QA) comes in - not as a final check, but as an ongoing, strategic process that ensures everything runs smoothly from the start. One of the biggest mistakes companies make is putting off QA until later. By then, fixing issues becomes expensive and time-consuming. A robust QA process starts right from the planning stage. QA shouldn't be an island. Developers, designers, project managers, and QA engineers should work as a team. Communication is key. Clear documentation, shared expectations, and open feedback loops help avoid misunderstandings and missed bugs. You can't fix what you don't track. That's why a well-defined test plan is essential. It sets expectations, outlines goals, and defines what success looks like. Manual testing has its place, especially when it comes to exploratory testing or checking visual and UX elements. But automation is the backbone of a scalable QA process. Smoke tests Regression tests API testing Cross-browser checks Tools like Selenium, Cypress, or Playwright can help speed up the process. Don't overdo it with automation, though - maintaining flaky tests can slow down your team more than it helps. Pro tip: CI/CD integration Hook automated tests into your CI/CD pipeline. That way, every time new code is pushed out, it's tested instantly. Faster feedback = fewer issues in production.

    🧩 Understanding Why Omit and Pick Fail with Union Types
    Omit and Pick are some of the most loved utility types in TypeScript. They let you create new types by excluding or selecting specific properties from an existing type. union types, their behavior can be misleading - and in some cases, break your type expectations type Employee = { id: string name: string job_name: string } type Customer = { id: string name: string company: string } type Person = Employee | Customer ❌ Problem: Using Omit Directly type PersonWithoutId = Omit 🧨 Actual Result: type PersonWithoutId = { name: string } Only name survives. The fields job_name and company are lost. Why? not distributive over union types. It collapses the union into a common structure, then removes the property - resulting in a simplified, lossy type. ✅ Solution: DistributiveOmit We can fix this by explicitly distributing Omit across each union member: type DistributiveOmit = T extends any ?

    MSP40: The Iron Throne of Industrial Networks
    In the smoldering forges of Old Valyria, where data flows like wildfire and downtime is the true enemy, there sits a sovereign of steel and silicon—the MSP40. Forged in the fires of precision and armored against chaos, this managed Ethernet switch defends the Seven Realms of Industry 4.0 with the ruthlessness of Tywin Lannister and the foresight of Bran the Broken. Let us declare why this switch claims the Iron Throne of industrial IoT. Chapter 1: The Forge of Dragonstone MSP40 is no mere ironborn gadget. Tempered in the Foundries of Valyrian Steel, it wields powers unseen since the Age of Heroes: Dragonflame Resilience: Operates from -40°C to +85°C—hotter than Drogon’s breath, colder than the Night King’s touch. Why it shatters the old order: Legacy Switches: As reliable as Joffrey’s promises—crumbling under pressure. Chapter 2: The War of Five Ports The Battle of Blackwater Bay (Smart Factories): MSP40 commands robotic arms with the precision of Arya’s Needle, slashing downtime like Lannister soldiers. “Chaos isn’t a pit. It’s a 40% productivity gain,” it whispers. The Siege of Winterfell (Power Grids): Guards substations against EMP storms, steadfast as Brienne’s oath. “The North remembers… surge protection.” The Red Wedding (Traffic Systems): Halts data collisions at smart intersections, sparing cities from King’s Landing-level gridlock. “The network sends its regards.” The Words of House MSP40 Ports: 12 channels of fury—8 RJ45 knights and 4 SFP dragons. The Dragons of Innovation The Dark Threats Beyond the Wall Legacy Switches: Bloat like Robert Baratheon’s reign, guzzling budgets and sanity. The Prophecy of the Prince That Was Plugged In Epilogue: Winter is Here (And It’s Buffering) the MSP40 is to court chaos—a realm of molten slag and screaming CFOs. The night is dark and full of packet loss.

    Why Data Versioning Matters in Machine Learning Projects
    Building reproducible models' accuracy is equally essential with model performance results in today's rapidly evolving machine learning (ML) environment. The practice of tracking and managing changes to datasets through time receives insufficient attention despite the focus on selecting the correct algorithms and adjusting hyperparameters. Data versioning practice is a critical management system that succeeds or fails an entire ML project. Reproducibility and Traceability Machine learning functions best when researchers maintain the ability to reproduce their outcomes. Model result reproducibility transforms into a random guessing process when you fail to version your data. When you retrain your model, it should deliver uniform results after each dataset variation. However, imagine seeing …  ( 6 min )

    A Recipe for Success: Cooking Up Repeatable Agentic Workflows
    The Remy-Linguini Dynamic If you haven't seen the movie, here's the gist: Remy is an incredible chef with all the know-how, but he's a rat, so no kitchen access. Linguini is a kitchen worker with full access but little cooking skill. Together, they form a symbiotic relationship: Remy hides under Linguini's hat and guides him on what tools to use and when. If a customer orders fries, Linguini might freeze, but Remy scopes out the kitchen, sees what's available, and gives step-by-step instructions: "Grab a knife and a cutting board. Now slice the potato." Then, Linguini executes the plan. Agentic systems work similarly. You have three core components: A Large Language Model (LLM) An Agent Tools The LLM is like Remy; it is full of knowledge and reasoning, but has no hands-on access. Th…  ( 7 min )

    Python Code Quality: Style Conventions and Linting Tools
    Leapcell: The Best of Serverless Web Hosting The Python code style guide is not set in stone. It evolves continuously with the development of the language. Some old conventions are gradually phased out, and new ones keep emerging. At the same time, many projects have their own coding style guides. When there are conflicts, the project-specific guides should be followed first. However, there is an important principle to keep in mind: "The stupid persistence in consistency is the monster of ignorance", which is a profound insight from Guido. Since code is often read more frequently than it is written, the core goal of the style guide is to improve code readability and keep all kinds of Python code consistent. As PEP20 says, "Readability counts". The style guide emphasizes consistency. While …  ( 10 min )

    DevLog 20250506 C# Video Processing Foundation Library
    Today I need to find a suitable foundational library for video processing. FFMpegCore works for one-shot things but despite a fluent API, its interface is still too command line like. Here is what I found out: OpenCvSharp LibVLCSharp FFMediaToolkit Frames ✅ decode / encode ✅ (via callbacks) ❓ Audio ❌ ✅ decode / encode / mux ❓ Extra libs ~5 MB/platform +7 MB +7 MB Licence Apache‑2.0 LGPLv2.1 MIT Platforms Win / mac / Linux / Arm Win / mac / Linux / iOS / Android Win / mac / Linux LibVLCSharp seems more focused on directly displaying things (e.g. in Xamarine and WPF) instead of low-level API based processing; FFMediaToolkit, on the other hand, still depends on FFMPEG and can't avoid licensing issue. Eventually, I had to go with separate video + audio processing in favor of OpenCvSharp (it's Apache-2.0 by the way). Notice OpenCVSharp has some advantage over EmguCV for custom dev: OpenCvSharp Emgu.CV Licence Apache-2.0 (fully permissive) GPL v3 or commercial licence Interop model Pure P/Invoke (no C++/CLI), works on any .NET core runtime Historically C++/CLI wrapper (needs Windows for full feature set), .NET Standard P/Invoke layer added later NuGet size (native) 4–6 MB per RID (modular runtime packages) 30 MB + for the “opencv‑world” monolith, or 90 MB for emgucv‑runtime‑ubuntu GPU (CUDA) support Provided in separate OpenCvSharp4.runtime.dnn package Official CUDA builds, but Windows‑only binaries unless you compile yourself API surface ~1:1 with OpenCV C++ names (easy to port C++ samples) Thicker .NET façade (e.g. Image types), extra helpers Cross‑platform stability Actively tested on Windows / Linux / macOS / arm64 Windows the main focus; Linux/macOS possible with libopencv from distro or big runtime package Learning curve If you know OpenCV C++ you feel at home Higher‑level abstractions can be friendlier for newcomers Commercial support Community‑driven Paid licences & support available from Emgu CV, Inc.  ( 3 min )
    🗄️ Best Practices for Handling Multiple Schemas in the Same Database Across Applications (with Real-World Lessons & Code)
    "Just because it’s one database doesn’t mean it should act like one app." Managing multiple applications using a single database with multiple schemas sounds clean—until things start to break under load. Here's what we learned the hard way and how you can handle it better. We had: 🧵 Microservices for modules like user-service, order-service, etc. 🗃️ All shared the same PostgreSQL DB using dedicated schemas (user_schema, order_schema, ...). 🪝 Each app pointed to the same datasource (JDBC URL), but with different search_path schema config. What we expected: Clean schema separation with easy analytics and joins. What we got: Connection leaks, poor connection pool behavior, and schema confusion. With one shared datasource and multiple apps hitting the DB simultaneously, connections kept tim…  ( 4 min )
    How does Heap Allocation Work in Rust?

    Here’s Why You’re Probably Taking the Wrong Approach to Integration
    Let’s talk about something few developers admit out loud: we're still doing integration wrong. Sure, we’ve moved beyond FTP dumps and cron jobs—hopefully.

    [Patch Notice] I found a problem of HeadlineSquare's HTML rendering, and today I patched the bug. All clear now.
    Semicolons were often added to the end of URLs, especially in r/Conservative summaries, and they became a part of the hyperlinks wrongly, making some of the hyperlinks unusable. I often randomly test the hyperlinks and they all worked, but I just realize that I only test the longest hyperlinks, because I think they are the ones more prone to hallucinations. I didn't find any hallucinations. But yesterday I clicked some of the simpler links of r/Conservative summaries and I got 30% of them not working. I panicked because I thought the hallucination caught me off guard, but then I realized all the links were real, but they each got an additional ";" attached to them, which was redundant. The links themselves were correct but the semicolons I used to declare the end of line was wrongly identified as part of the URLs. The fix was simple. I removed all redundant semicolons from all my current and previous output documents. I am really surprised of this bug because it affected so many links but it evaded my "random" sampling for so long, because I didn't test the rendered URL links very thoroughly, and I thought very long and complex links were at higher risks of hallucination, so I tested those a lot. Weird enough, those never had problems, but the shorter, simpler links did. I am very sorry for the potential confusion it might have created.  ( 3 min )

    Falling DXY part of US financial system’s ‘long-term transition’ — Will Bitcoin continue to shine?
    What to know: Lyn Alden says a weaker dollar is necessary for the US to stabilize its financial system. Bitcoin and gold are well-positioned to benefit from de-dollarization. Sovereign wealth funds and various nations are already increasing their Bitcoin exposure as the dollar’s global dominance starts to wane.

    SocialFi has failed to take off — Here's what needs to change
    Opinion by: Anurag Arjun, co-founder of Avail  On paper, SocialFi is a no-brainer. It promises to shift the balance of power in social media — giving people control over how their content and personal data are used and monetized. It even offers users a stake in the $200+ billion social media advertising market, a pie currently devoured almost entirely by giants like Meta. And yet, SocialFi platforms today feel more like digital ghost towns than the bustling hubs of Web2. Friend.tech, hailed as a breakout star in 2023, peaked at just 80,000 daily active users before falling below 10,000. What's holding SocialFi back? Why does it seem to be following Friend.tech's fade into obscurity rather than rising to rival Facebook's dominance? The harsh reality is that decentralized social networks hav…

    Crypto miner deserts Pennsylvania site, fails to plug wells: Report
    Cryptocurrency miner Diversified Energy quietly vacated a natural gas-powered crypto mining site in Elk County, Pennsylvania, reportedly leaving behind unplugged wells and regulatory violations. The site, known as Longhorn Pad A, was revived in 2022 after sitting dormant for nearly a decade when Diversified began using it to fuel on-site generators powering cryptocurrency mining computers, according to a report by the Erie Times-News. Per the report, the operation was launched without obtaining an air quality permit from the Pennsylvania Department of Environmental Protection (DEP). Though the company was later granted the permit in December 2023, a March 2025 inspection revealed that Diversified had already removed the mining infrastructure.

    What is Tornado Cash, and why did it get into trouble?
    What is Tornado Cash? Tornado Cash is a decentralized, non-custodial crypto mixer designed to enhance transaction privacy on public blockchains.

    Hacken CEO sees ‘no shift’ in crypto security as April hacks hit $357M

    The Relationship Between GDP and Stock Market Performance
    The relationship between Gross Domestic Product (GDP) and stock market performance is a subject of considerable interest to economists, investors, and policy makers alike. GDP measures the total value of goods and services produced by a country, and it serves as an indicator of the health and growth of an economy. The stock market, on the other hand, reflects the collective value of publicly traded companies and serves as a platform for buying and selling shares. Both metrics are often used to gauge economic conditions, yet their relationship is more complex than a simple correlation. While there is a connection between GDP growth and stock market performance, this relationship is influenced by various factors, including investor sentiment, economic policies, and external events. In some c…  ( 7 min )
    Creating A2A Agents with Python: Building a Simple Math Agent - Part II
    In this blog post, I'll walk through how I built a simple Agent-to-Agent (A2A) math service using Python. The A2A protocol is Google's initiative to standardize how AI agents communicate with each other, creating an interoperable ecosystem of specialized AI services. The Agent-to-Agent (A2A) protocol is designed to enable AI agents to communicate with each other using a standardized messaging format. This allows developers to create specialized agents that can work together, each handling specific tasks they're optimized for.

    Testing in the Era of Microservices and APIs: A Leadership Perspective
    There was a time when software releases were slow and monolithic—but at least everything was in one place. Now, we move faster. But that speed? It comes at a cost. Today, we live in a world of microservices, APIs, and distributed everything. The architecture is elegant. The orchestration is powerful. But testing? That’s where things get tricky. As a quality engineering leader, I’ve seen firsthand how this complexity tests more than just code—it tests our assumptions about ownership, accountability, and what “done” really means. In a microservices ecosystem, a single user journey might hit a dozen services. Each is built, deployed, and owned by a different team. And while unit tests may pass with flying colors, it’s the integration points—those fragile handshakes between services—that often…  ( 4 min )
    How to Optimize Java Map for Variable Key Structures?
    Introduction In Java, managing complex key structures dynamically is a common challenge, especially when dealing with API response times and performance issues. In your scenario, you're saving keys in a map formatted like Krishna/thota/date/x/y/z while supporting wildcard characters (*) to match various entries. However, this approach leads to performance overhead due to the necessity of comparing strings, which can be inefficient when handling over a million records. We’ll explore better data structures and solutions to enhance performance while allowing for the flexibility you need for matching.

    Beyond Heroes and Villains
    When a small purple dragon leapt joyfully onto television screens in 1998, gaming felt simpler. Spyro's tale was charmingly clear-cut: dragons good, Gnorcs bad. Yet, as those early fans grew alongside the medium itself, uncomplicated childhood memories gave way to reflective curiosity. With maturity comes the realisation that even playful narratives can unwittingly reveal complex truths—sometimes challenging, always intriguing. Among Spyro's cast, no group invites this reconsideration quite like the Gnorcs. Originally depicted as brutish, green-skinned adversaries to vanquish without second thought, today they stir conversation far beyond simple nostalgia. Central to this renewed interrogation of Spyro's world is Gnasty Gnorc himself. Once an outright villain, his motivations now appear le…  ( 6 min )
    The Documentation Paradox
    Most teams spend hours documenting everything. Notion workspaces. Confluence pages. GitHub wikis. You name it. But here’s what happens: ☑️New hires still get stuck. ☑️Devs still ask questions that are, “Somewhere in the docs” and crucial context gets lost. This is the Documentation Paradox: The more you write, the harder it gets to find, trust, and maintain what actually matters. Conventional wisdom says, “Async teams need tons of docs!” But I’ll say: More docs often mean less clarity. Here’s why: First, there's the maintenance burden. Every line of documentation is a liability that needs updating as your codebase evolves. How many teams actually do that? Second, comprehensive documentation creates a false sense of security. Teams believe they're covered because it's in the docs somewhere. What you should do is treat documentation as a conversation, not an artifact. Use tools that make updating docs as easy as sending a message. Encourage annotations and questions directly in the documentation. And remember the 20/80 rule: 20% of your features generate 80% of questions. Focus your efforts there. The goal isn't to have everything documented – it's to have the right documentation that actually helps your team move faster. This is why every Rally session lives forever inside Jira No more sorting through old Slack threads. Every discussion stays tied to the task, so your team’s knowledge grows with the work—not in a dusty folder.  ( 3 min )

    How to Humanize Strings in C# Like Ruby's Humanize?
    In C#, there isn't a built-in method equivalent to Ruby's humanize for turning strings into a more natural format, but you can create functions to achieve this easily. In this article, we'll explore how to convert strings while following the two scenarios provided in your request: changing capitalization and formatting string cases to appear more human-friendly. Understanding the Humanization Process When we discuss 'humanizing' a string, we're typically referring to text transformation that makes it easier for humans to read or understand. This can involve adjusting capitalization, changing the case, or formatting text to look more polished and readable. Unlike Ruby, where the humanize function applies well-defined transformations, C# requires us to craft our own methods. Implementing a S…  ( 4 min )

    How to Fix Diesel Count Query Error in Rust
    Introduction When working with Rust and Diesel, you may encounter various issues, especially when performing count queries. In this article, we'll examine a specific error that arises from executing a count query using Diesel with PostgreSQL. The error message states, 'the trait bound i32: FromSql is not satisfied'. This indicates a type mismatch in your query resolution. Understanding the Error The error is primarily triggered because the Diesel ORM expects a specific data type from the SQL count result. Typically, when using the count function in a SQL query, the result is of type BigInt in PostgreSQL, which corresponds to i64 in Rust. However, your code attempts to return the result as an i32, leading to the compile error. Step-by-Step Solution Changing Return Type to i64 Th…  ( 4 min )

    How to Use CodeIgniter Query Builder for SQL Queries?
    When working with CodeIgniter, you might want to utilize its query builder feature for better performance and security. For instance, let's consider the SQL query: SELECT * FROM questions WHERE course_id = 13; This query retrieves all records from the 'questions' table where the course_id is equal to 13. However, using raw SQL queries in CodeIgniter, as shown below, can lead to issues: $query2 = $this->db->query('SELECT * FROM questions WHERE course_id = 13', false); Why is This Query Problematic? Using this method can lead to potential SQL injection vulnerabilities, and it's not as efficient as using the CodeIgniter Query Builder. Additionally, the parameters need to be validated or sanitized especially when you’re dealing with user input. Using the Query Builder in CodeIgniter The Code…  ( 4 min )

    Dica de TI: O que são tipos de dados?
    Dica de TI será uma série de posts com conteúdo sobre tecnologia. São posts curtos explicando alguns conceitos. Um tipo de dados representa as características de uma variável que determina que tipo de dados ela pode conter. Exemplo tipos de dados primitivos: Essas variáveis guardam valores. Exemplo: números, byte, short, int, long, float, double e boolean char. A aplicação guarda o endereço em memória e não o valor em si. Importantes casos são as arrays e os objetos. Exemplos Arrays, Objetos, Classes, String. Os tipos primitivos são predefinidos (já definidos) em Java. Tipos não primitivos são criados pelo programador e não são definidos. Tipos não primitivos podem ser usados para chamar métodos para realizar determinadas operações, enquanto tipos primitivos não podem. Um tipo primitivo sempre tem um valor, enquanto os tipos não primitivos podem ser null. Um tipo primitivo começa com uma letra minúscula, enquanto os tipos não primitivos começam com uma letra maiúscula. Exemplos de tipos não primitivos são Strings , Arrays , Classes, Interface , etc.  ( 3 min )
    Sightful's Spacetop Is a Better, More Practical Spatial Computing Experience
    Sightful’s Spacetop for Windows is a $899 bundle (plus a $200/yr subscription after year one) that turns your compatible Intel-powered laptop and Xreal Air 2 Ultra smart glasses into a multi-monitor, spatial-computing workspace. Wired gave it a 9/10, praising its polished software, comfy glasses (with dimming for outdoor use) and the private, ultra-portable productivity it delivers—arguably edging out Apple’s Vision Pro at a fraction of the price. It’s not all sunshine, though: the setup looks a bit dorky, only works on select Intel CPUs for now, saps battery life in a hurry and the glasses’ field of view could be wider. Still, if you’ve been dreaming of carrying your home-office everywhere, Spacetop might finally make it happen.  ( 3 min )

    Greetings to all!

The name is conditional, but the essence is important. The term "usual state" refers to data that is saved directly due to the state managers, or due to the internal functionality of the framework or library.

    Implementing the Royal Game of Ur using Mistral's Codestral
    In this post, I test how Mistral's Codestral, the model specifically trained to generate code, compares to the Mistral's Le Chat, the general AI chat. For my experiment, I use the Royal Game of Ur, an ancient Babylonian game that I already implemented using Le Chat. At least in my experiment, Codestral's performance is, frankly, disappointing.

    Restarting Laravel Queue Workers Safely
    When managing background processes or queue workers in a production environment, Supervisor is often the go-to process control system. But if you’ve ever worked with Supervisor on a Linux server, you've likely come across these two commands: sudo service supervisor restart && sudo supervisorctl restart [program_name] They might look similar at a glance — both contain the word restart — but they operate at very different levels and are used in very different situations. Let’s break down what each command does, when to use it, and what to avoid in a production environment. 🔍 1. sudo service supervisor restart ✅ What it does This command restarts the Supervisor daemon itself — not just the programs it manages. Think of it as turning Supervisor completely off and then back on. When you run …  ( 4 min )

    Cloud-Native: Are You Paying for What You Use… or for What You Provision?
    Everyone’s in the cloud. Stacks have migrated. Infrastructure is containerized. CI/CD pipelines are green. But behind the wave of “cloudification”, one question lingers: Have we really changed the way we think? Because on the surface, everything looks modern. But underneath? ⏱️ Services running 24/7 💤 Containers sitting idle, waiting for traffic that never comes 💸 Bills growing, even when no one clicks “deploy” And in every retro, every finance meeting, the same old line: “The cloud is expensive.” But is it really the cloud that’s expensive? Or is it… The quiet luxury of feeding CPUs that are just bored? Let’s be honest. Cloud-native isn’t Docker. It’s not Kubernetes. It’s not Terraform, or some magic mix of YAML, containers, and CI/CD. Those are tools. Powerful ones. But tools. Clo…  ( 5 min )
    Smarter RAG Systems with Graphs
    Introduction: So You Want Your LLM to Stop Guessing Everyone’s buzzing about Retrieval-Augmented Generation (RAG) like it’s the second coming of AI engineering. And honestly? It kinda is. Your large language model is excellent at confidently making things up—because it doesn’t actually know anything beyond whatever data it was last trained on (hello, 2023). That’s where RAG comes in: bolting on real, external knowledge so your LLM stops hallucinating and starts reasoning. But here’s the thing: knowledge isn’t just about facts. It’s about how things connect. And when relationships matter, you don’t want a flat file or a relational torture device. You want a graph. Enter the graph database.

    How to Dynamically Pivot Object Keys in SQL?
    In this article, we will explore how to dynamically transform a table in SQL where object keys become column names and their values populate corresponding columns. This scenario is common for database tasks involving JSON-like structures, particularly in systems like Snowflake. By utilizing advanced SQL techniques, you can simplify data manipulation and achieve a transformed view of your data without explicitly naming each key. Understanding the Problem The need to pivot object keys arises when you have a table with a column storing semi-structured data types like objects. In our case, we have a table objects_to_pivot where the attributes column contains various object keys that might not be consistent across rows. The challenge is to convert these dynamic object keys into fixed column nam…  ( 5 min )
    Why Financial Calculations Go Wrong, and How to Get Them Right
    When building systems that handle money, there’s no room for approximation. A minor rounding error or a misplaced use of floating-point arithmetic can lead to inconsistencies, broken user trust, or even financial loss.

    EventTarget - CustomEvent | components communication in React - part Three
    In the first and second parts, we focused on creating two different patterns for handling data flow in React. EventTarget is the foundation of the browser’s event system. addEventListener, removeEventListener, and dispatchEvent. Many core Web APIs including DOM elements like , , , as well as document and window inherit from EventTarget. When we attach an event handler to a DOM element—like in the picture above—we’re actually subscribing to that element through one of its event channels. In this case: The button is the publisher (or emitter) The callback function passed to addEventListener is the subscriber (or listener) So when a user clicks the button, the button emits a 'click' event, and all registered listeners for that event type are notified and executed. So with…  ( 5 min )
    Beyond the Bugs: How Software Testing Fuels Innovation 🚀
    I’m a product owner, guiding a team building a collaboration app for remote workers. Last quarter, we rushed a feature—real-time document editing—without thorough testing. It launched buggy, crashing for users with large files. Clients churned, and our team’s morale tanked. Testing isn’t just about finding bugs—it’s about enabling us to push boundaries. In April 2025, software testing drives innovation, giving us confidence to experiment and deliver bold features. This isn’t a technical deep-dive or buzzword parade—it’s my story of how testing fuels progress, shared for professionals who want to innovate without breaking things. Testing is often seen as a bug hunt, but it’s so much more. It’s the engine that powers bold ideas, protects user trust, and keeps teams moving fast. Our app’s cra…  ( 7 min )
    The Spirit of Plan 9 on the Web
    If you go back to the first talk ever given on webhooks, it opens on the command-line. Specifically the Unix shell, focusing on one of its defining features: pipes. The idea was that pipes brought a new level of compositionality to programs, and webhooks could bring a new level of compositionality to web apps. Perhaps you could say I was trying to bring the spirit of Unix to the web. With this last release of Wanix, I'm at it again. This time with the successor to Unix, a little known operating system called Plan 9 from Bell Labs. Plan 9 has been on my mind for quite a while. In fact, around the time of that first talk on webhooks, the team behind Unix and Plan 9 was being re-assembled to create the Go programming language. I pretty instantly fell in love with the Go worldview, which turns…  ( 5 min )

    #6 DP: Decorator
    O que é o Padrão Decorator? O Decorator é um padrão de projeto estrutural que permite adicionar comportamentos adicionais a um objeto de forma dinâmica. Ele permite que você encadeie funcionalidades (como validação, construção, logging e outras) em um fluxo sequencial, sem modificar a estrutura original da classe. Isso possibilita adicionar ou remover comportamentos com facilidade, mantendo o código mais flexível e desacoplado. Em resumo, o Decorator cria uma cadeia de responsabilidades onde cada classe pode adicionar sua funcionalidade à sequência, sem afetar as outras. Imagina que você precisa realizar várias validações (como validar o usuário, estoque e status), mas não quer que elas fiquem fortemente acopladas. O objetivo é poder adicionar, remover ou reorganizar facilmente as valida…  ( 4 min )

    TS2327: Property '{0}' is optional in type '{1}' but required in type '{2}'
    TS2327: Property '{0}' is optional in type '{1}' but required in type '{2}' TypeScript has quickly become a favorite tool for developers building scalable and maintainable JavaScript applications. At its core, TypeScript is a superset of JavaScript—it builds upon JavaScript by introducing static typing, as well as other modern programming concepts that make your code safer and easier to manage. Static typing means that developers can explicitly define the types of data (like string, number, or boolean) their variables and functions work with, catching potential errors during development instead of at runtime. If you're new to TypeScript, or want to sharpen your existing skills, consider following our blog or using advanced learning tools like gpteach.us to explore how modern AI tools ca…  ( 6 min )
    TS2333: 'this' cannot be referenced in constructor arguments
    TS2333: 'this' cannot be referenced in constructor arguments TypeScript is a statically-typed superset of JavaScript designed to add type safety and developer-friendly features to JavaScript code. A "superset" means that TypeScript builds on JavaScript by adding new functionalities, while still allowing you to write plain JavaScript. One of its most powerful features is the introduction of types (a system to define constraints on the structure of your data). This is immensely beneficial when working in large projects to detect errors at compile time, ensuring your codebase is reliable and maintainable. Types in TypeScript help us describe the shape of an object, function, or data. For instance, when you define a function or an object, you can explicitly specify what inputs it expects and…  ( 6 min )
    TS2332: 'this' cannot be referenced in current location
    TS2332: 'this' cannot be referenced in current location TypeScript is a popular open-source programming language developed by Microsoft. It’s often referred to as a superset of JavaScript because it builds on JavaScript by adding optional static types. These types allow developers to define the structure and behavior of variables, functions, and objects, making programs easier to debug and maintain. TypeScript compiles to plain JavaScript for execution, which means it seamlessly integrates with existing JavaScript projects. Simply put, types in TypeScript are what allow you to specify the kind of data a variable or function should handle. For instance, you can declare that a variable must always hold a number, a string, or a custom structure (like objects or classes). By catching errors …  ( 6 min )
    TS2331: 'this' cannot be referenced in a module or namespace body
    TS2331: 'this' cannot be referenced in a module or namespace body TypeScript is a powerful language that builds upon JavaScript by adding optional static typing. By introducing "types" (representations of data such as strings, numbers, and objects, among others), TypeScript allows developers to write more predictable and maintainable code. It’s often referred to as a superset (a language that extends the features of another) of JavaScript, meaning all valid JavaScript code is also valid TypeScript code. A major advantage of TypeScript is its ability to catch errors during development, before the code is executed. However, while it enhances safety and boosts productivity, developers may sometimes encounter compiler errors that seem confusing at first. One such error is TS2331: 'this' ca…  ( 5 min )
    TS2329: Index signature for type '{0}' is missing in type '{1}'
    TS2329: Index signature for type '{0}' is missing in type '{1}' TypeScript is a strongly typed superset of JavaScript. This means that it builds on top of JavaScript by adding an optional type system (a way to define and enforce the kinds of data being used in your code). TypeScript is a powerful language designed to catch errors early during development, making your JavaScript codebases more robust and maintainable. In TypeScript, "types" play a central role. A type defines the shape of data, specifying what kind of data will be stored, its expected structure, and the operations you can perform on it. For example, string, number, boolean, and object are common types used in TypeScript. Types ensure that your code only operates on the data it was designed to handle; if it doesn’t match t…  ( 6 min )
    TS1433: Decorators may not be applied to 'this' parameters
    TS1433: Decorators may not be applied to 'this' parameters TypeScript is a strongly-typed programming language that builds on JavaScript by adding static types (data classifications, such as string or number). TypeScript helps developers write safer, more predictable code because it allows the compiler to catch potential bugs during the development process, before the code is executed. Essentially, TypeScript acts as a typed superset of JavaScript, meaning it includes all the features of JavaScript while adding new functionalities, mainly focused on type safety.

    🚀 Turning Videos into Interactive Courses with AI
    How I built VidSabio.com by combining multiple LLMs into a robust processing pipeline I recently launched VidSabio, a platform that transforms ordinary videos into structured, interactive learning experiences — automatically. 🎥➡️📚 But this didn’t come together overnight. At first, I thought a single LLM could handle everything: analyze the video, transcribe it, generate quizzes, build a course. Easy, right? Wrong. It turned out the real breakthrough came when I stopped looking for one model to do it all — and instead built a pipeline of specialized steps, each powered by the best tool for that specific task. Here’s the high-level breakdown of how it works: User uploads a video Video is processed through a multi-step pipeline: Frame extraction (FFmpeg) Audio transcription (Google Speech-to-Text) Visual analysis (Gemini / GPT-4 Vision) Content summarization + topic generation (Gemini Pro) Course structure generation (GPT-4) Interactivity injection (quizzes, accordions, etc.) Final course can be edited and exported as SCORM or HTML This is all built using Vue 3, Firebase, and various LLMs (OpenAI + Gemini) stitched together through Cloud Functions. By distributing the heavy lifting across multiple LLMs and APIs, I was able to: Improve accuracy Scale more efficiently Debug and retry isolated steps Customize outputs based on step-level feedback Frontend: Vue 3 + Tailwind Backend: Firebase Functions + Firestore + Storage AI: GPT-4.1, Gemini Pro, Whisper, Google Speech-to-Text Analytics: PostHog Export: SCORM, HTML Here's a stylized diagram of the flow: (Insert your HappyAlien-styled image here) This was built with plenty of detours, dead ends, and "aha" moments. If you're building with LLMs, I encourage you to explore multi-model orchestration — it might be the key to your next breakthrough.

    Leading with Conviction, Listening with an Open Mind
    A piece of feedback that reshaped how I think about conviction, consensus, and presence when you're the most senior person in the room. Originally published at mustafatorun.me A few years ago, I wrote a design document outlining a few different options. It was for a group more experienced than me—not in the domain, but in the industry. I knew the problem well. I had done the work. But still, I softened my position. I showed the tradeoffs, invited discussion, and held back from saying with confidence, “This is the direction I believe we should take.” In a pre-review, someone I trusted — someone more experienced than me — called it out. The document lacked conviction. It read like I was asking the group to decide for me. They reminded me that I was the expert in this domain — not them. What …  ( 4 min )

    10 JavaScript Array Functions Every Dev Must Know (or Risk Falling Behind)
    If you’ve started learning JavaScript, you’ve probably worked with arrays — those magical lists that hold multiple values. But knowing how to use arrays effectively means understanding the array functions that JavaScript gives us. Let’s break down the most powerful and commonly used array functions that every developer should know. An array is a special variable in JavaScript that can hold more than one value at a time: const fruits = ['apple', 'banana', 'cherry']; .push() – Add to the End fruits.push('mango'); console.log(fruits); // ['apple', 'banana', 'cherry', 'mango'] .pop() – Remove from the End fruits.pop(); console.log(fruits); // ['apple', 'banana', 'cherry'] .shift() – Remove from the Start fruits.shift(); console.log(fruits); // ['banana', 'cherry'] .unshift()…  ( 4 min )

    How to Transform Snake Case to Camel Case in TypeScript?
    When working with APIs, we often encounter data in formats that do not match our application's preferred coding style. For instance, if you're using TypeScript and Vue.js, you might receive data in snake_case from an API but prefer to work with camelCase throughout your application. The good news is that you can easily transform this data without losing type safety. Let's delve into how you can achieve that with the help of interfaces and utility types in TypeScript. Understanding the Problem When you define an interface such as MergedReviewDetails, you structure your data according to your application's needs. An example of this could be: export interface MergedReviewDetails { parentReview: Mmcid; childReviews: Mmcid[]; } However, the API might return data with properties in snake_ca…  ( 4 min )

    What is Tailgating?
    In the world of corporate security, not all breaches involve sophisticated hacking tools—some simply walk through the front door. Tailgating, a subtle yet dangerous form of intrusion, happens when an unauthorized person gains access to a restricted area by following closely behind someone who is authorized. It's a tactic that relies less on technology and more on exploiting human behavior. Attackers often masquerade as employees, contractors, or delivery workers. They may carry packages, wear uniforms, or claim to have forgotten their access badge—all to lower suspicion. Once inside, these individuals can do far more than just roam the premises. They might access critical systems, plant malicious software, or steal sensitive equipment. Pretending to be a colleague and asking someone to hol…  ( 4 min )

    The Day I Discovered enumerate()
    It was a regular evening debug session. My code was working, but something about it just felt off. I was looping over a list—like always. for i in range(len(my_list)): value = my_list[i] # Do something with value and i Nothing wrong, right? Except... I was starting to hate reading my own code. range(len(...)). Too much manual indexing. 👀 The Realization for i, value in enumerate(my_list): # Do something with i and value Wait... what? No range(len(...))? No messy indexing? ✅ Cleaner 🧠 Why it works: enumerate() is a built-in Python function that returns both the index and the value of items in an iterable—in one shot. It’s like your loop suddenly gained superpowers. 💡 Bonus Tip: for i, val in enumerate(my_list, start=1): print(f"Item {i}: {val}") Perfect for user-facing counters. No more +1 hacks. 🚫 Never Again... No more range(len(...)) unless I really need it. Now, it’s all enumerate(), all day. ✨ Moral of the Story: If you're reaching for range(len(...)), stop and ask yourself— What would enumerate() do? 😎  ( 3 min )
    How to Access Fields with Spaces in Lumerical FDTD Farfield Data?
    When working with Lumerical FDTD simulations, access to specific fields from the results of a far-field projection monitor might sometimes be challenging, especially when it comes to field names with spaces. In your case, you're able to access standard fields like E2 and Es easily: farfield = getresult("monitor", "farfield"); E2 = farfield.E2; Es = farfield.Es; However, when it comes to the field "Ep vs angle", an error arises. This can happen due to the space in the field name, making direct access using dot notation invalid. Understanding the Structure of the Farfield Object The farfield object typically contains several fields, including E2, Es, and multiple arrays or matrices concerning angles and wavelengths. The fields you can access directly using dot notation are designed to be id…  ( 4 min )

    Introduction When working with Svelte and TypeScript, you might run into challenges regarding event typing. A common scenario involves handling input events from an element and wanting to replace the generic any type with a more specific InputEvent. This article will explore how to accurately type the input event in Svelte using TypeScript, allowing you to harness the benefits of type checking while eliminating the use of any. Understanding the Issue You are currently using an input handler function that looks like this: function emitChange(event: any) { const text = event.target.value; dispatch("changeContent", { text }); } While this function works, it relies on the any type, which defeats the purpose of using TypeScript. In your attempt to switch to InputEvent, you enco…  ( 4 min )

    RDMA에 대하여
    RDMA(Remote Direct Memory Access)는 네트워크를 통해 서버 간에 CPU 개입 없이 메모리를 직접 읽고 쓰는 기술이다. 주로 고성능 컴퓨팅(HPC), 대규모 데이터 처리, AI/ML 분산 학습 환경 등에서 낮은 지연 시간과 높은 대역폭을 제공하기 때문에 많이 사용한다. 1. RDMA의 기본 개념 일반적인 네트워크 통신 방식에서는 데이터를 전송하려면 CPU가 메모리에서 데이터를 읽고, 네트워크 인터페이스 카드(NIC)로 복사한다. 이 복사한 데이터를 네트워크를 통해 데이터를 보내고, 수신 측에서도 CPU가 데이터를 NIC에서 메모리로 복사한다. 이 과정에서 CPU, 커널, 복사 작업 등이 개입되어 지연(latency)과 CPU 오버헤드가 큰 현상이 발생한다. 반면, RDMA는, CPU나 운영체제(OS) 커널의 개입 없이, 원격 시스템의 메모리에 직접 읽기(read) 또는 쓰기(write) 작업을 수행한다. 다시 말해, 데이터가 직접 메모리에서 메모리로 이동한다. 2. RDMA가 동작하는 방식 (1) 메모리 등록 (Memory Registration) 송신자와 수신자 모두 RDMA NIC(HCA: Host Channel Adapter)를 사용함. RDMA를 사용하기 위해서는 사용할 메모리 영역을 등록(pinning)해야 함. 이 과정에서 해당 메모리는 물리 메모리에 고정되고 커널이 RDMA NIC에 메모리 주소를 알려줌. (2) Queue Pair 생성 RDMA 통신은 QP(Queue Pair)라는 구조를 통해 이루어짐.

    The Scraping Story: The Car Repair Team
    The Scraper: The Collector of Car Parts Each day, the Scraper ventured out, gathering essential tools—brake pads, spark plugs, and oil filters—meticulously putting them in his storage room. This storage room, filled with parts, was like a database, organizing all the precious data he gathered from various sources. For instance, one day, the Scraper found a batch of brake pads. He cataloged the details, from brand to condition, and stored it safely. This was like collecting the latest prices from websites, storing them in a file for future use. The Backend Guy: The Toolbox Handler Whenever the mechanic—the Frontend—needed a specific tool, they would call out, “I need a 10mm wrench!” The Backend Guy, standing by the toolbox, would find the correct tool and hand it over with precision. He didn't fix the car himself, but he made sure the mechanic had exactly what was needed at the right time. Just like that, the Backend Guy managed the storage of all the data and ensured it was always ready when the Frontend needed it. When the mechanic asked for the current price of the Euro in Toman, the Backend would retrieve that data and send it in a neat package—a JSON response—ready to be used. The Frontend Mechanic: The User Interface When the mechanic needed a part, they'd shout, "I need a 10mm wrench!" The Backend Guy would respond, handing over the tool, and the Frontend Mechanic would get to work. The mechanic didn’t care how the part got there, as long as it was the right one. In the same way, the Frontend Mechanic used the data provided by the Backend to create an amazing display for the car's dashboard. They made sure the car (or website) looked stunning, with neatly organized parts (like the prices) and a smooth-running engine (user interface). Whether it was showing prices in a nice table or providing a simple, user-friendly experience, the Frontend Mechanic made sure everything was visually appealing and functional.  ( 4 min )

    IaCConf 2025: Why Infrastructure as Code deserves its own conference
    Infrastructure as Code (IaC) has come a long way since its beginnings. What started as spinning up cloud resources has now grown into a full-blown ecosystem with a very engaged community. IaC on its own can add a lot of complexity to your processes and cause more issues, but combined with governance, compliance, security, deployment strategies, self-service, it easily becomes the fuel your delivery engine needs. This year, IaCConf debuts as a virtual event by bringing together this community, and it’s shaping up to be one of the most relevant and practical events in the space. Unlike broader DevOps/SRE or cloud-native events, IACConf is focused on the challenges and innovations around defining infrastructure as code. That means the content goes deeper, the conversations are more relevant, and the takeaways are directly applicable to your processes. There will be sessions on: Getting started with IaC Managing IaC at scale across teams and environments (using OpenTofu, Terraform, Ansible, Crossplane, and others) Platform Engineering and IaC How IaC impacts your maturity AI in IaC And that’s just scratching the surface. Check out the full agenda here. One of the things I appreciate most about this conference is that it’s not about product pitches or high-level fluff. Practitioners share what worked, what broke, and how they improved. Whether you are just starting out, are in the trenches, or shaping platform strategy, there’s something for you here. On another note, I’m also excited to contribute to this year’s lineup with a session on Getting Started with IaC, together with my colleague Emin Alemdar. But honestly, I’m just as excited to learn and to connect with others working through the same challenges. The event will be on Thu, May 15, 2025 @ 11:00am EDT, so don’t forget to register here.

    🚀 Developing with Golang: A Beginner's First Steps
    By a beginner, for beginners. When I first started learning Go (Golang), everything felt a little strange. Coming from the Python and JavaScript background😅😅., I expected to deal with new syntax, but I didn’t expect to get stuck on the very first line of every Go file: package main I remember asking myself: "Why do we declare the package name before the start of any code?" 📦 What Is a Package in Go? In Go, as well as other languages like Python, a package is a way to organize and reuse code. Every .go file must start by declaring which package it belongs to. There are two kinds of packages you’ll encounter early on: main: This package is special. It tells the Go compiler that this file is part of an executable program. Library packages: These are packages meant to be imported into othe…  ( 4 min )

    Is It Safe to Transmute Between OuterA and OuterB in Rust?
    In Rust, understanding how std::mem::transmute functions between different types is crucial for ensuring memory safety and type integrity. This brings us to an interesting question: Is it safe to transmute between two custom struct types, OuterA and OuterB, which only differ by their inner types — InnerA and InnerB? Let's explore what the repr(transparent) conveys and clarify the implications of transmuting types in Rust. Understanding repr(transparent) The #[repr(transparent)] attribute in Rust is used to indicate that a struct represents a single variant of a type that can be safely treated as equivalent to its single field. This is particularly useful for effectively working with opaque types or for implementing newtype patterns. In the provided example, we have the following structur…  ( 4 min )

    How to Properly Implement mat-list and mat-divider in Angular?
    Introduction When developing Angular applications, particularly with Angular Material, you might encounter issues regarding the mat-list and mat-divider components. Many developers wonder whether to use ngFor inside the mat-list or the mat-list-item and how to correctly place the mat-divider. Let’s delve into this topic to clarify which method is best. Why This Issue Arises The confusion around where to implement ngFor and the positioning of mat-divider often stems from how Angular handles component rendering. Using ngFor within the mat-list means that each item is rendered as part of the list itself; thus, the dividers are less likely to show correctly if their placement isn’t considered carefully. Conversely, applying ngFor to mat-list-item makes each list item independent and potentiall…  ( 4 min )

    What is a Proxy Firewall and How Does It Work?
    A proxy firewall, often referred to as an application-layer or gateway firewall, acts as an intermediary between a user’s system and external servers. Instead of allowing direct communication, it processes and forwards requests on behalf of users. This not only hides internal network details from outsiders but also allows the firewall to thoroughly inspect data before it reaches its destination. Unlike traditional firewalls that operate primarily at the network or transport layer, proxy firewalls operate at the application layer. They intercept requests, evaluate the content, and relay approved traffic. This additional layer of inspection allows for more granular control, helping detect threats embedded in seemingly legitimate requests—such as malware hidden in web traffic or email attachm…  ( 4 min )

    LLM 훈련/추론 시 총 메모리 크기는?
    국내 기업들을 방문해서 AI 인프라 관련 분들을 만나면, 가장 많이 물어보는 질문들 중 하나가 LLM 추론 시 메모리 크기는 얼마나 되는 것인 가이다. 아무래도내부에 가진 서버를 그대로 사용할 것인가? 아니면 신규로 서버를 구매할 것인가?에 대해 LLM을 동작 시킬 때 총 메모리 용량이 얼마나 되는 지 궁금해서 일 것이다. 예를 들어, meta-llama/Meta-Llama-3-8B-Instruct에서 훈련(Training) 또는 추론(Inference)할 때, Tensor Type으로 BF16 이면 메모리 크기는 얼마이며, 몇 장의 GPU를 사용해야 하는가에 대해 묻는다면, 어떻게 답변을 해야 하는지 알아 볼 것이다 메모리 사용량 개략적 계산 = (모델 파라미터 * 2) + 파라미터의 2 - 3배 BF16(bfloat16)은 FP16과 마찬가지로 16비트 정밀도를 사용하므로, 기본적으로 모델 파라미터*자체가 차지하는 메모리는 FP16 대비 큰 차이가 없음. AdamW 와 같은 옵티마이저 상태나 그래디언트, 중간 활성화 (activations) 등으로 인해 실제 요구되는 메모리는 2~3배 가량 될 수 있음. 계산식: (16 * 2) + (16GB * 2 or 16GB * 3) = 32GB + (32 or 48 )GB = 64 or 80 GB BF16 타입으로 풀 파인튜닝(Full fine-tuning)시 단일 GPU으로는 최소 40GB 이상, 안정적인 배치 크기 확보를 위해서는 A100/H100 80GB급이 1장이 권장 80GB H100 1장으로 분산 학습을 활용해도 충분히 학습이 가능함.…  ( 4 min )
    🧠🚀Open project for discussion: OS Against Porn - Anyone interested in implementing it?🧩
    Hello, I have an ambitious technical idea that I hope to share with the community of developers and cybersecurity specialists: Given the widespread prevalence of pornographic content online, and the difficulty of controlling it through traditional blocking or weak censorship tools, I've come up with a new system: 🔐 An "ethical operating system" (for smart devices – such as Android, iOS, and Windows) built from the ground up on the principle of: "Completely blocking any type of pornographic content, whether visual or textual, whether on websites, apps, search engines, or social networks." 💡 Key features of the idea: Its protection cannot be hacked or changed (such as the inability to install an alternative system). It can be installed on children's devices, school devices, or even the devices of adults who want to protect themselves. It doesn't rely solely on blocking a specific site, but rather on real-time content analysis. A clean app store and a clean built-in search engine. 🧱 Technically: Or as a distribution for children, schools, or conservative environments. Or even as a layer of security added to existing systems (e.g., Android). 🎯 The goal is not to impose censorship, but rather to provide a safe, ethical, and educational alternative. 🤝 I'm looking for: Interested programmers. Note that I'm only 16 years old. The goal is to find someone who will embrace this idea. Suggestions for improving the idea. Any technical or community support is possible.

    Concurrency in Python
    Fundamentals of Concurrency Concurrency: Managing multiple tasks simultaneously to improve responsiveness. Threads and asyncio operate on a single processor, switching tasks. Multiprocessing achieves true parallelism by using multiple CPU cores. Parallelism: Running tasks literally at the same time on different processors. Types of Tasks: I/O-Bound: Limited by input/output operations (e.g., network, file system). CPU-Bound: Limited by the processor's computational power. Concurrency Models Threading: Use for I/O-bound tasks. Managed by the OS (preemptive multitasking). Python module: threading, concurrent.futures.ThreadPoolExecutor. Asyncio: Best for I/O-bound tasks. Uses cooperative multitasking (tasks decide when to yield control). Requires…  ( 11 min )

    How BIMI Integrates with Email Authentication Protocols
    In a world of growing email threats, a brand impersonation is one of the most damaging and widespread forms of phishing. As we know that organizations need more than just secure email delivery — they need visible proof of authenticity. That is why BIMI (Brand Indicators for Message Identification) comes into play. Actually BIMI allows brands to display their logo directly in recipients’ inboxes, that offering visual trust and higher engagement. However, for BIMI to function, it must depend on strong email authentication protocols already in place. BIMI is a standard that lets organizations to publish their brand logo in a specific format (SVG) through DNS. When supported by the mailbox provider, actually the logo appears next to the authenticated emails in the recipient’s inbox. This not …  ( 5 min )
    What Content to Create and How to Publish It, Part 2
    Overview In today's digital landscape, creating compelling and polished content is essential for capturing and retaining audience attention. The publication should not be overly dense or difficult to read. 2500 words. On the other hand, the size should not be too small, where it can be consumed in just one minute. 800 words as the smallest size for a publication. An important point to note is the absence of any formatting symbols in the publication, such as or   . There is a recommendation for citations to be formatted as in-line links, with any recommended reading listed separately. If you use tables in your publications, please make sure that columns with less content are placed towards the end of the table, and vice versa.

    Interviewing Software Developers: From Junior to Architect in a Single Programming Task
    Over the years, I’ve interviewed around 100 software developers at Google and roughly the same number across my own companies. One thing has become very clear: Resumes don’t work. They’re too noisy. You get flooded with titles, buzzwords, and irrelevant project summaries. So I distilled everything down to one single task. One prompt I can give to anyone — junior or architect — and instantly get a signal. The task? Write a library that calculates the sum of a vector of values. That’s it. No extra requirements. The beauty is that it looks trivial — but the depth reveals itself as the candidate explores edge cases, generalization, scalability, performance, and design. Most junior candidates start like this: int Sum(int* data, size_t num_elements) { int result = 0; for (size_t i = 0; i…  ( 5 min )

    What Is the Role Of Delegates in Objective-c in 2025?
    Objective-C has long been a mainstay in the development of applications for iOS and macOS. Despite the rise of Swift, Objective-C remains a relevant and powerful language, particularly for maintaining legacy code and integrating with newer Swift code bases. As we move into 2025, understanding core patterns like delegation continues to be vital for developers working with Objective-C. Delegation is a design pattern used in Objective-C to pass messages between objects and to provide a mechanism for customization of behavior. It allows one object to delegate tasks to another, enabling a clear separation of responsibilities and enhancing the modularity of applications. Typically, a delegate object implements methods from a protocol to respond to certain events or actions occurring in the deleg…  ( 4 min )

    Replacing Lambda Triggers with EventBridge in S3-to-Glue Workflows
    In one of our production data platforms, we used Lambda functions to trigger AWS Glue jobs every time a file landed in an S3 folder. That setup worked fine when there were only two or three data sources. But as the system expanded to support more than 10 folders, it required deploying and maintaining an equal number of nearly identical Lambda functions, each wired to specific prefixes and jobs. The architecture became increasingly brittle and harder to manage. This post outlines how that structure was replaced using EventBridge, with prefix-based filtering and direct Glue job targets. No Lambda. No maintenance overhead. Using S3 events to trigger Lambda comes with several limitations: A single Lambda function can’t be mapped to multiple S3 prefixes Each one requires separate deploymen…  ( 5 min )
    Encapsulation
    To Understand Encapsulation please do check out last post Encapsulation is like a medicine capsule: the outer shell hides the complex ingredient inside, delivering only the intended effect to your body. You don't need to know the chemical makeup to benefit from it. Encapsulation is achieved through the use of access modifiers. Python primarily uses two types of access modifier. Private: Accessible from anywhere. Public: Accessible only within the class. Similarly, in programming, encapsulation wraps data and methods in a class, exposing a simple, controlled interface while keeping the internal details private and secure. Let say I want to make "model" attribute private so that nobody can manipulate the model name. So make it private just add '__model' So, question arise if we can't access attribute but we can access function which include the private attribute. Think of like if we have attribute which you don't want get manipulated then make it private.  ( 3 min )
    How to Fix CarouselView Not Displaying Images in MAUI
    Introduction If you're developing a MAUI application and are facing issues with the CarouselView control not displaying images from an ObservableCollection, you are not alone. This article will address why images may not show up in your CarouselView, even when the same image sources work perfectly with a standard Image control. Understanding CarouselView in MAUI The CarouselView in .NET MAUI is designed to display a collection of items in a swipeable format. Each item can be customized using a DataTemplate, which lets you define how each item appears. Typically, developers use ObservableCollection to bind dynamic data to CarouselView because it notifies the view of changes. However, while you may see indicators appear correctly, images may not load as expected. Common Issues with CarouselV…  ( 4 min )
    What Is the Purpose Of Dynamic Typing in Objective-c?
    Objective-C, a primary programming language used for macOS and iOS development, has always been appreciated for its unique blend of C's efficiency and Smalltalk's dynamism. A critical feature that sets it apart from other languages is its support for **dynamic typing**. This allows for a flexible development process that enhances code modularity and adaptability. But what truly is the purpose of dynamic typing in Objective-C? ## What is Dynamic Typing? Dynamic typing refers to the ability of a programming language to determine the type of an object at runtime, rather than during compile-time. This contrasts with static typing, where the type of an object is known and enforced during compilation. In Objective-C, this means you do not have to specify the class type of an object, providing …  ( 4 min )
    Using Tailwind JIT Mode for Faster Development
    If you're still not using Tailwind CSS JIT (Just-in-Time) mode in your development workflow, you're seriously missing out on one of the biggest productivity boosts Tailwind has ever introduced.

    How to Select N Messages with Sum of Verbosity Less than N?
    Selecting messages with a specified sum of verbosity can be challenging in SQL, especially when the goal is to find all messages where the sum of a specific column stays below a certain threshold. In this case, we want to find messages from a table with a specified verbosity value such that the summed values of verbosity for a given set of rows remain under a specified limit, N. Understanding the Problem In our example, we have a simple table named messages, which contains two columns: id and verbosity. Given the entries: | id | verbosity | |----|-----------| | 1 | 20 | | 2 | 20 | | 3 | 20 | | 4 | 30 | | 5 | 100 | When we wish to choose rows whose sum of verbosity is less than a certain value, say N = 70, we expect to select the rows with ids 1, 2, an…  ( 4 min )

    🧠 State Management in Flutter: Choosing Between Bloc, Riverpod, and Provider
    Flutter makes building beautiful UIs fast and fun — but what happens when your app starts growing? When screens need to react to shared data? That’s when state management becomes essential. In this blog, we'll demystify state management in Flutter and help you decide between Bloc, Riverpod, and Provider — three of the most popular approaches in the Flutter ecosystem. State refers to the data your UI depends on. For example: A counter’s value Whether the user is logged in The list of items in a shopping cart State management is how we keep the UI in sync with the data — especially when multiple widgets care about the same data or when data changes over time. There are two broad types: Local state (e.g., setState inside a single widget) Global/shared state (e.g., auth status, theme, user pre…  ( 5 min )
    Why does fieldClass.getDeclaredFields() return empty in JDK 17?
    Introduction If you're using Java Development Kit (JDK) 17 and noticing that your call to fieldClass.getDeclaredFields() returns an empty array, you're not alone. Many developers have encountered this issue when attempting to retrieve field information from classes in the Java Reflection API. The Java Reflection API is essential for inspecting classes at runtime, allowing developers to gather information about fields, methods, and constructors programmatically. However, certain security restrictions in JDK 17 can lead to unexpected behavior, including the inability to reflectively access declared fields in classes like Field.class from the java.lang.reflect package. Understanding the Root Cause In JDK 17, Java introduced a more robust module system that enforces strong encapsulation by def…  ( 5 min )

    What is fine-tuning in AI?
    Fine-tuning in Artificial Intelligence (AI) refers to the process of taking a pre-trained model and adapting it to a specific task or dataset. Pre-trained models, especially large ones like GPT (from OpenAI) or BERT (from Google), are initially trained on massive datasets using general-purpose data. These models learn a broad understanding of language, patterns, or image features. However, for specialized tasks—like medical diagnosis, legal document analysis, or customer sentiment detection—fine-tuning helps the model learn domain-specific nuances. The process involves continuing the training of the model with a smaller, task-specific dataset while adjusting the model’s weights slightly. This method allows the model to retain its general knowledge while becoming more effective in the target domain. Fine-tuning is far more efficient than training a model from scratch, saving both computational resources and time. There are different levels of fine-tuning. Some approaches adjust only the final layers of the neural network (known as feature extraction), while others allow all layers to be updated (full fine-tuning). Techniques like parameter-efficient fine-tuning (PEFT), such as LoRA (Low-Rank Adaptation), are gaining popularity, especially for large language models, because they minimize the number of parameters updated. Fine-tuning is used in a variety of real-world applications, including chatbots, image generation, fraud detection, and more. It’s especially powerful in scenarios where labeled data is limited but high-quality outputs are essential. With the growth of open-source and pre-trained foundation models, fine-tuning has become a key skill for AI practitioners. To master techniques like fine-tuning, transfer learning, and prompt engineering, enrolling in a Generative AI certification course is highly recommended.  ( 3 min )
    ExpRoot+Log: A Linear and Universal Basis for Function Approximation
    Abstract We introduce a novel numerical method, ExpRoot+Log, for function approximation based on a hybrid linear basis consisting of exponential-square-root, polynomial, and logarithmic components. This method achieves high accuracy across smooth, discontinuous, and rapidly decaying functions while remaining simple, interpretable, and computationally efficient. We show that ExpRoot+Log outperforms classical approaches such as polynomials, splines, Fourier series, and even neural networks in key scenarios, offering a new universal baseline for practical approximation. Introduction Function approximation is fundamental to numerical analysis, physics, machine learning, and signal processing. Classical bases—polynomials, splines, and trigonometric functions—have known limitations, especially near discontinuities or exponential decays. While neural networks provide expressive power, they are complex, opaque, and computationally expensive. We propose a new hybrid basis: This composition handles: All coefficients are learned linearly (e.g., via least-squares), ensuring ultra-fast performance and excellent stability. Numerical Evaluation We tested ExpRoot+Log against standard methods (polynomials, splines, Fourier) across six function types: Sine Exponential decay Step function Gaussian spike Absolute value Composite (piecewise mix) ExpRoot+Log consistently achieved 1–4 orders of magnitude lower error than polynomials or Fourier bases.

    Introduction to access control model: ACL, RBAC, ABAC
    Access Control Models: ACL, RBAC, ABAC In system design, access control is a critical mechanism to ensure data security and correct authorization of functionalities. Depending on the complexity of the system, the variety of user roles, and the flexibility needed in resource management, there are three common access control models: ACL (Access Control List), RBAC (Role-Based Access Control), and ABAC (Attribute-Based Access Control). Below is a brief comparison of these three models, outlining their design logic, characteristics, and application scenarios to help clarify the selection and implementation considerations.

    Neuralese: The Most Spoken Language You’ll Never Speak
    Somewhere between thinking and speaking, there’s a strange place where meaning starts to solidify. It’s not quite a word yet. More like a haze of associations. A mental sketch your brain tries to translate into something shareable. Sometimes it works. Most of the time it doesn’t, at least for me. I tend to mumble a lot. That private language in your head, the one you use to talk to yourself, isn’t English or Portuguese or Python. It’s not even a language, really. It’s raw and messy. A kind of silent shorthand sculpted by experience. Try catching it. Try explaining it. It slips through like fog in your fingers. Science is already poking around in there. Researchers are feeding brain signals into neural networks and getting fuzzy images back. They’re trying to reverse-engineer what we see, d…  ( 7 min )

    Why Engineering Teams Should Build Their Own AI Coding Agents

The highest-performing teams will be defined by the proprietary AI systems they've built, customized for their specific codebases, architectural patterns, and business domains. These teams will wield AI as a strategic differentiator, not merely consume it. This is where our industry is clearly headed. As AI increasingly becomes the primary author of code across industries, the strategic advantage will shift from who can write the best code to who can best direct, customize, and optimize AI systems to write that code.

    The code review chaos we faced with GitLab (and what we tried to fix it)
    I've worked in several agile teams as both a developer and lead developer. One particular project sticks in my mind — a team of ten people, dozens of microservices, and a lot of GitLab repositories to manage. During each sprint, we were juggling features across multiple repos. At the same time, we were responsible for reviewing each other’s code. Our typical flow was: Open a merge request (MR) on GitLab Move the related Jira ticket Share the MR link in a Teams channel Move on to the next story When the workload was light, it was manageable. But in busy sprints, reviews piled up quickly. Large MRs got ignored, or rushed through. And tracking what was waiting, what was blocked, or what still needed input? A mess. We experimented with several ideas: Using GitLab labels like needs-review or blocked Adding Jira tags Rotating reviewer ownership by repo each sprint They helped — but they didn’t solve the root problem: lack of visibility and timing. Code reviews were often asynchronous and scattered. We were switching contexts constantly, jumping between repos, and forgetting which contributions needed our attention. We didn’t need more tools — we needed a better way to surface and track reviews. Something that would: Give us a unified view of MRs Let us know what’s ready to merge, what’s waiting, and what’s blocked Respect our flow, instead of interrupting it That’s when I started working on a side project, aiming to solve this specific pain point. That side project became Bellugo — a contribution tracker designed to help teams stay on top of reviews across repositories without the chaos. It’s still a work in progress, but if this resonates with your team, I’d love for you to check out the landing page and maybe join the private beta waitlist.  ( 4 min )

    Very Basic - Redux
    Learning Redux is a real pain in the @#$#$^&. Good thing the team I was on at the time I learned it highly valued taking the time to learn, because it took me a good 30 out of 40 hours of a work week to figure out what the eff was going on. Once I finally did learn it however, I realized that the majority of what slowed me down in the learning process was that I couldn’t find a great explanation of exactly what Redux was doing. All I could find were tutorials on how to use it, and not really very much info on how it worked. I’m going to try to solve that issue with this post.

    Singly Linked Lists - DSA Notes 📝
    🎯 Learning Goals What are the characteristics of Singly Linked Lists? What are its time complexities? ListNode? Has a value and a next pointer next is a reference to another ListNode Order in memory may not be contiguous (unlike arrays which are) Simple while loop with a current pointer can be used: cur = ListNode1 while cur: cur = cur.next ⌚ Time complexity is O(n) , where n is the number of nodes in the linked list Now if the Linked List is circular (i.e. last node points back to first) traversing like this would cause an infinite loop. It would be helpful if we’re keeping track of the head and the tail of the linked list using pointers Advantage over array is that inserting is always O(1) even if we insert in middle. Let’s say we wanna add at the end or tail : tail.next = NewListNode tail = NewListNode # or this line 'tail = tail.next', both are correct ⌚ Time complexity is O(1) Removing any node is constant time ASSUMING we have a pointer to the previous node. Let’s say we wanna remove the second node: head.next = head.next.next # Just set the next pointer of head to the one after the deleted node Can be assumed that garbage collection will take place for the deleted node ⌚ Time complexity is O(1) For both of these operations, the caveat is if we don’t have a reference to the node at the desired position (head or tail), the time will still be O(n) Operation Big-O Reading/ Access O(n) Traversal/ Search O(n) Insertion O(1)* Deletion O(1)* *Assumes you have a reference to the node at the position (if not it is O(n) ) 206.

    US regulator moves to drop appeal against Kalshi

    Bitcoin could rally regardless of what the Federal Reserve FOMC decides this week: Here’s why
    Key Takeaways: The Fed may pause rates but inject liquidity. Crypto could rally as a recession hedge. The weak US dollar and gold rally signal a shift to scarce assets. The US Federal Reserve Open Market Committee (FOMC) interest rate decision on May 7 will be a defining moment for risk-on assets, including cryptocurrencies. While the consensus points to no change in interest rates, Bitcoin (BTC) and altcoins could see gains if the US Treasury is compelled to inject liquidity to stave off an economic recession. A more accommodative monetary policy could stimulate activity, but the Federal Reserve (Fed) is also contending with a weakening US dollar. Some analysts argue that a US interest rate cut may fail to stimulate growth as recession risks persist, potentially creating an ideal envir…

    Bitcoin price rallied 1,550% the last time the ‘BTC risk-off’ metric fell this low
    Key Takeaways: The Bitcoin Risk-Off signal dropped to 23.7, its lowest since March 2019, indicating low correction risk and a high likelihood of a bullish trend developing. Despite the recent decline in network activity, bullish macro indicators like the Macro Chain Index (MCI) suggest Bitcoin could soon rally above $100,000.

    North Korean spy slips up, reveals ties in fake job interview
    For months, Cointelegraph took part in an investigation centered around a suspected North Korean operative that uncovered a cluster of threat actors attempting to score freelancing gigs in the cryptocurrency industry. The investigation was led by Heiner Garcia, a cyber threat intelligence expert at Telefónica and a blockchain security researcher. Garcia uncovered how North Korean operatives secured freelance work online even without using a VPN. Garcia’s analysis linked the applicant to a network of GitHub accounts and fake Japanese identities believed to be associated with North Korean operations.

    Frictionless flows are Ethereum's path to economic dominance
    Opinion by: Barna Kiss, CEO of Malda An idea recently floated by some prominent thinkers in the Ethereum space to reclaim value for the mainnet is the taxing of its Layer-2s. The future of Ethereum does not depend on policy but on enabling frictionless capital movement between the L2s in question. Tariffing rollups may appear a neat way to reclaim value for the mainnet. In practice, it would fragment the ecosystem, drain liquidity, push users toward centralized platforms, and avoid decentralized finance altogether. In a permissionless system, capital flows to where it is treated best, and Ethereum's rollups mistreat it. Liquidity fragmentation is Ethereum's real threat In traditional finance, the link between fluidity and growth is well established. Lower barriers to capital inflows lead …
    What bankers, CPAs and CFOs need to know about blockchain
    Why finance veterans are still skeptical about blockchain Blockchain has been part of the finance conversation for over a decade now. Yet many professionals remain cautious.  Many seasoned professionals in finance, wealth management and economics often question blockchain’s relevance, asking, How exactly is blockchain supposed to fit into what we already do? This question reflects a few key ongoing skepticisms about blockchain within finance.

    Dem lawmakers object to hearing, citing 'Trump’s crypto corruption'
    Representative Maxine Waters, ranking member of the House Financial Services Committee (HFSC), led Democratic lawmakers out of a joint hearing on digital assets in response to what she called “the corruption of the President of the United States” concerning cryptocurrencies. In a May 6 joint hearing of the HFSC and House Committee on Agriculture, Rep. Waters remained standing while addressing Republican leadership, saying she intended to block proceedings due to Donald Trump’s corruption, “ownership of crypto,” and oversight of government agencies. Digital asset subcommittee chair Bryan Steil, seemingly taking advantage of a loophole in committee rules, said Republican lawmakers would continue with the event as a “roundtable” rather than a hearing. HFSC Chair French Hill urged lawmakers at the hearing to create a “lasting framework” on digital assets, but did not directly address any of Rep. Waters’ and Democrats’ concerns about Trump’s involvement with the crypto industry. He claimed Waters was making the hearing a partisan issue and shutting down discussion on a digital asset regulatory framework. This is a developing story, and further information will be added as it becomes available.

    US stablecoin bill loses democrats amid Trump corruption concerns
    Democratic lawmakers in Washington are backing off support for crypto legislation amid heightened concerns over corruption, including the conduct of the Trump family’s World Liberty Financial (WLFI).

    Blockchains ready for institutions, lawyers hesitate: DoubleZero CEO
    While blockchain infrastructure may be ready for institutional use, many legal teams at large firms remain cautious about full integration with the technology.  At the Token2049 event in Dubai, DoubleZero Labs founder and former Solana head of strategy Austin Federa told Cointelegraph that today's high-performance blockchains like Solana are technically capable of supporting large-scale institutional usage. However, lawyers still need to catch up.  “Most blockchains nowadays, especially things like Solana, are fast enough for institutions to use them,” Federa said. “It’s really more about the institutions and the institution’s lawyers getting comfortable with crypto.” Federa added that institutional lawyers and compliance teams are still addressing regulatory concerns.

    The Tron network has drawn closer to regaining the lead from Ethereum in Tether circulation after another big mint by the US stablecoin issuer. On May 5, Tether minted another $1 billion Tether (USDT) on the Tron network, according to Arkham Intelligence. This brings the total USDT on Tron to $71.4 billion, according to the Tether Transparency report.  In comparison, there is currently $72.8 billion USDT circulating on the Ethereum network, so just $1.4 billion more USDT on Tron will see it become the leading network for the world’s largest stablecoin issuer, as it has been previously over the last two years.  Tron was ahead of Ethereum for USDT circulation between July 2022 and November 2024, but a large $18 billion mint on Ethereum pushed the network ahead again, according to CryptoQuant…

    Samourai Wallet says feds hid advice that crypto mixer was in the clear
    Samourai Wallet’s lawyers allege federal prosecutors suppressed advice that the firm didn’t need a license before they charged executives at the crypto mixing service months later.  In a May 5 letter to a Manhattan federal court, lawyers for Samourai co-founders Keonne Rodriguez and William Hill said prosecutors disclosed that the US Treasury Department’s Financial Crimes Enforcement Network (FinCEN) representatives told them six months before they charged the pair “that under FinCEN’s guidance, the Samourai Wallet app would not qualify as a ‘Money Services Business’ requiring a FinCEN license.” “Shockingly, six months later, the same prosecutors criminally charged Keonne Rodriguez and William Hill with operating just such a business without a FinCEN license,” the lawyers added.

    How to Specify a Different Linker in GCC and Clang?
    Introduction When compiling programs in C or C++ using cc or c++, you may find yourself needing to use a different linker than the default one. For instance, your version of GCC or Clang might link against /usr/bin/ld. In many scenarios, developers want to test their applications with alternative linkers, like /usr/local/bin/ld, for various reasons, including performance evaluation or compatibility testing. In this article, we’ll explore how to specify a different linker without running separate compilation steps. Why the Default Linker Matters The linker plays a crucial role in the compilation process, as it's responsible for combining different object files into a single executable. By default, compilers like GCC and Clang use a hard-coded linker, typically located at /usr/bin/ld on Unix…  ( 4 min )

    Landing from Clouds: Why On-Premise Will Eventually Win
    “The computer industry is the only industry that is more fashion-driven than women’s fashion.” Larry Ellison In our era, the cloud is the haute couture of infrastructure. Everyone wants it. Everyone says you need it. And few ask whether it actually fits. This post is for those who remember that not every problem needs 12 layers of abstraction. It's for careful builders who believe that owning your tools is better than renting your soul. And here are 12 reasons why on-premise will outlast the hype. The cloud sells convenience, but charges premium rent, forever. When you buy servers, you own an asset. When you rent a VM, you feed a meter.

    How to Fix Modal Animation Issues with Button Elements
    Understanding the Issue with Modal Animations If you've ever tried to implement a modal that slides in from the bottom after being triggered by a button, you might have encountered an unexpected behavior when using a element inside your modal dialog. This is a common issue that developers face, especially when working with CSS animations. In this article, we will explore why this issue occurs and how you can fix it effectively. Why Does This Happen? The problem often arises from the way CSS handles layout changes during animations. When the modal is opened, if a button element is included, it may trigger a reflow in the browser’s layout engine. This reflow can result in the appearance of a scrollbar, which disrupts the fluidity of your animation. The pointer-events property combin…  ( 4 min )

    Evite requisições desnecessárias com debounce em JavaScript
    Você já digitou algo em um campo de busca e, a cada letra digitada, uma nova requisição era feita para a API? Isso é ineficiente. A solução? debounce() debounce? É uma técnica usada para adiar a execução de uma função até que um tempo específico tenha passado sem novas chamadas. É muito usado em: buscas dinâmicas (auto-complete) eventos de rolagem (scroll) eventos de resize Imagine um campo de busca que chama a API a cada tecla: function search(term) { fetch(`https://api.exemplo.com/search?q=${term}`) .then(res => res.json()) .then(console.log); } input.addEventListener("input", (e) => { search(e.target.value); }); Isso gera chamadas demais. Agora, com debounce: function debounce(fn, delay) { let timer; return (...args) => { clearTimeout(timer); timer = setTimeout(() => fn(...args), delay); }; } const debouncedSearch = debounce(search, 500); input.addEventListener("input", (e) => { debouncedSearch(e.target.value); }); Agora só é chamada a API depois que o usuário parar de digitar por 500ms. No React, pode usar com useCallback ou bibliotecas como lodash.debounce: import debounce from 'lodash.debounce'; const debounced = useCallback( debounce((value) => { // chamada de API aqui }, 300), [] ); Conta aqui nos comentários como implementou 👇 Ou salva esse post pra usar depois! 🔖  ( 3 min )
    How to Remove Cast in Hibernate Queries for DB2 z/OS?
    Introduction If you're working with Hibernate and querying a DB2 z/OS database, you might have faced a common issue where the generated SQL queries include unnecessary cast statements, especially after upgrading to Hibernate 6. This can cause errors as certain DB2 versions don't support those casts. In this article, we will explore why this issue occurs and provide solutions to remove the cast statements for compatibility with DB2 z/OS. Understanding the Problem In Hibernate, SQL query generation can change between versions due to changes in how Hibernate handles type conversions.

    Understanding Laravel's Arr::dot() Method
    When working with deeply nested arrays in Laravel, especially when handling configuration files, API responses, or multidimensional data structures, managing or accessing values quickly becomes complex. Laravel’s Arr::dot() method offers a clean, efficient way to flatten these arrays using “dot” notation, making them much easier to work with. In this article, we’ll explore what Arr::dot() does, how it works, and when you might want to use it. The Arr::dot() method in Laravel flattens a multidimensional array into a single-level array using dot notation for keys. This transformation allows you to access deeply nested values with a simple key string. Arr::dot(array $array, string $prepend = '') $prepend: (Optional) A string to prefix each key in the final array. This method is part of Laravel’s Illuminate\Support\Arr helper class. Let’s take a look at a typical example: Input Array $data = [ Applying Arr::dot() $flattened = Arr::dot($data); print_r($flattened); [ 'user.name' => 'John', 1. Configuration Files 2. Localization 3. Form Handling Bonus: Reversing the Flattening $nested = Arr::undot($flattened); Arr::dot() is a small but powerful utility in Laravel that simplifies the handling of complex arrays. Whether you're building APIs, working with config files, or cleaning up nested data structures, this helper can be a time-saver and make your code cleaner and more readable. Next time you're faced with a deeply nested array, consider reaching for Arr::dot() — you’ll appreciate the simplicity it brings.  ( 4 min )

    Comprehensive Exploration of the Permissions API for Managing User Consent Historical and Technical Context The emergence of web technologies has ushered in a new era of interactivity and real-time applications. However, with such capabilities comes the critical responsibility of user privacy and consent. The Permissions API was standardized as part of the broader movement to provide enhanced privacy practices on the web, enabling developers to manage user permissions more systematically.

    How to Create a PHP Registration Form as a Single Page Application?
    Creating a multi-page registration form in PHP can be cumbersome, especially when the pages require reloading for navigation. If you're experiencing slow load times with your current method—where each page requires a new HTTP request—you might want to consider converting your form into a Single Page Application (SPA). This approach enhances user experience by loading the HTML just once and using JavaScript to handle navigation smoothly. Understanding the Issue When using multiple pages for form registration, each time a user clicks the 'Next' button, a new HTTP request is sent to the server, which loads a new page. This results in a complete refresh, including reloading CSS, JavaScript, and images, leading to inefficient use of resources and slow loading speeds. A Single Page Application a…  ( 4 min )
    New browser in town

Today I saw this video https://youtu.be/9YM7pDMLvr4?si=R7X_wdJVqqRB3TNB Andreas explaining what is Ladybird browser and why they are developing it. So I went to https://github.com/LadybirdBrowser/ladybird checked out the code and build it on WSL2 Windows 11, took around 3 hours to compile and finally it worked UI looks similar to Firefox and feels like #Netscape in 1999, and it is developed actively, I hope we have a new and free browser because feels like Firefox is not that free anymore and Google has been too strong on browser market, it would be nice to have a real non-profit browser here. Maybe government/countries should support this kind of organizations otherwise browsers or OSes becoming like citizen monitoring tools and used for profit and manipulation, After we say internet is a human right that human should have the option of non monitored communication use in their home. And in the YouTube video Andreas talks about SerenityOS which looks very similar to Windows 95, good old days. It is a good idea to have unix like OS as desktop.

    🚀 Do zero ao primeiro SaaS: 3 erros que me ensinaram mais do que qualquer acerto
    Em janeiro, decidi tirar minha ideia de SaaS do papel. O objetivo? Aprender na prática como levar um produto do conceito à loja. Confesso que foi uma onda de desafios (e ainda está sendo!). Como era meu primeiro projeto, cometi vários equívocos. Eu queria compartilhar alguns abaixo ⤵️ — e como eles estão me ajudando a evoluir: 🔥 Planejamento impulsivo   Fui direto da ideia para a solução, sem mapear etapas ou prazos. Resultado? Retrabalho e ansiedade. Hoje, priorizo ferramentas de gerenciamento e cronogramas flexíveis para manter o foco sem engessar a criatividade. 🔍 Validação superficial   Criei o SaaS para resolver meu problema, mas não validei se era uma dor real do mercado. Consequência? Perdi tempo competindo com soluções já consolidadas. Aprendi que entrevistas com potenciais usuários são tão importantes quanto o código. 💸 Precificação "no feeling"   Foquei em funcionalidades incríveis, mas não pensei em como monetizá-las de forma atraente. Lição? Agora estudo modelos de precificação antes de sair desenvolvendo novas features, usando cases de sucesso como referência. ✨ O saldo positivo?   Esses tropeços me deram algo valioso: clareza. Hoje entendo melhor que errar faz parte do processo — desde que cada erro vire um degrau para iterar. E você? Já passou por situações assim em seus projetos?  ( 3 min )

    When developing applications that involve Bluetooth Low Energy (BLE) communication, you might encounter connection issues with certain BLE devices. In this guide, we will focus on troubleshooting a case where one BLE device connects successfully while another fails to establish a connection even after initial setups seem correct. This situation can lead to frustration, especially if logs indicate that connections are attempted but not finalized. Let's explore some common reasons for this behaviour and how to address them effectively. Understanding BLE Connection Process Bluetooth Low Energy (BLE) allows for low-power communication between devices. Each BLE device offers various services and characteristics. Establishing a connection typically involves several steps, from enabling the Bluet…  ( 5 min )
    These DevOps KPIs Will Boost Your Performance In 2025
    As the DevOps landscape evolves, tracking the right KPIs (Key Performance Indicators) becomes more than a performance metric it becomes a strategy for continuous improvement, team alignment, and business value delivery. In 2025, DevOps is not just about shipping code faster. It's about delivering resilient, scalable, and secure systems while maintaining harmony across development and operations. Here’s a look at the most relevant KPIs DevOps teams should track in 2025 to ensure performance, productivity, and reliability are all on target. Deployment Frequency Why it matters: This KPI measures how often you deploy code to production. High-performing DevOps teams typically deploy multiple times per day. How to improve: •Automate CI/CD pipelines •Embrace feature flags and trunk-based development •Encourage smaller, incremental releases Pro tip: Pair this metric with Change Failure Rate to ensure quality isn't sacrificed for speed. Lead Time for Changes Change Failure Rate (CFR) Mean Time to Recovery (MTTR) System Uptime & Availability Developer Productivity Infrastructure as Code (IaC) Coverage Security Scan Success Rate Final Thoughts Want to dive deeper?

    GAEB4Linux – Open Source GAEB Viewer/Editor for Linux (Java/XML)
    Hey dev.to! GAEB4Linux, which aims to bring native support for GAEB files (a German construction industry standard) to Linux. GAEB is a widely used XML-based format for exchanging construction data in Germany. It’s essential for things like bills of quantities, tender submissions, costing, and invoicing. There are plenty of GAEB software tools available, but almost all of them are Windows-only or commercial. Linux users in the construction industry currently have no solid open-source solution to handle GAEB files. The goal is to create an open-source GAEB file viewer/editor for Linux (written in Java for cross-platform compatibility). The initial version will support: Viewing GAEB XML files (e.g., .X83, .X84), Entering bid data and prices for tenders, Later stages could include additional features like full AVA (tendering and invoicing) functionality. 🌱 Current Status: Right now, I’m in the early planning phase – no code has been written yet. I’m designing the system, figuring out the core features, and planning how to integrate the GAEB XML structure. Developers familiar with Java, XML, and GUI design (Swing/JavaFX, etc.), Anyone with experience in the construction industry or knowledge of GAEB/AVA workflows, Designers or UX/UI specialists who can help build an intuitive interface, Feedback from anyone who has worked with GAEB or similar standards. I’m planning to host the project on GitLab, and I’ll set up a chat (Discord/Matrix) for discussions and collaboration. Would love to hear your thoughts or suggestions, and I’m open to any tips from anyone who has experience with GAEB file handling. Thanks for reading! —Klaus  ( 3 min )

    Starvation in Javascript: When your program remains Hungry
    If you've spent time working with JavaScript's asynchronous model, you know that its single-threaded nature is both a blessing and a curse. On one hand, you don't have to worry about complex locking mechanisms. On the other, you might stumble into weird issues where your code just... never runs. One such issue is starvation. In the context of JavaScript, starvation refers to a situation where a task is perpetually delayed because the event loop is constantly busy with other tasks—usually of higher priority or those scheduled more frequently. Since JavaScript executes code in a single-threaded environment using an event loop, starvation can occur when: Long-running synchronous code blocks the event loop. Microtasks (Promises, MutationObservers, etc.) continuously prevent macrotasks (like se…  ( 4 min )

    “It Looked Right…” Famous Last Words Without Tests
    TL;DR: LLMs are great, but they’re not your safety net. Please, for the love of all things holy, test your code. We’re in the golden age of vibe coding. LLMs scaffold our code, fix our syntax, and fill in the blanks. We’re thinking more about architecture and less about syntax—and that’s great. But in all this abstraction, we sometimes skip something essential: testing. AI doesn’t run your code. It doesn't know if that method exists, if that call will throw an error, or if that edge case breaks everything. It’s bluffing with confidence. You can’t vibe your way through correctness. You need tests to know your code behaves the way you think it does. 🛡 Confidence to refactor without fear 🧠 Clarity around what your code is supposed to do 🔄 Continuity when you revisit the code 6 months later 🤝 Collaboration with teammates who now understand the logic A mentor once told me: “Start at the center—your happy case. Then go left, right, and fall off the line.” Say your function expects a positive integer. Start with 42. Then try: 0, -1, Infinity, -Infinity A string ("hello"), a float (3.14), or null Now take it further: What if the parameters are undefined? What if the database call fails? What if the API returns malformed or missing data? What if a field you depend on is null? The real world is messy. Your tests should be ready for that. As we stop writing every line ourselves, we need to start questioning every line more. AI will get you to “working”—but testing gets you to “works when it matters.” AI bluffs. Don’t let it bluff you into a broken release.  ( 3 min )

    Grumphp en proyectos Ddev
    Grumphp es un orquestador que permite configurar el uso de herramientas de código estático para PHP. Hasta hace relativamente poco tiempo he usado W4D como entorno de desarrollo en mis proyectos, pero hace un año me tocó probar Ddev para un proyecto y desde entonces me enamoré de todo lo que aporta este software. Ahora toca migrar proyectos que tengo con W4D a Ddev y una de las cosas que toca migrar es Grumphp. Para instalar Grumphp yo uso el paquete de Carcheky que está preparado para funcionar con Drupal y luego lo personalizo. Ejecuto el siguiente código para instalar el paquete: composer config extra.grumphp --json '{"config-default-path": "vendor/carcheky/drupal-grumphp/configs/grumphp.yml"}' ; composer require --dev carcheky/drupal-grumphp -W Una vez instalado copio el archivo grumphp.yml que se encuentra en vendor/carcheky/drupal-grumphp/configs/grumphp.yml a la misma altura del archivo composer.json En el archvio composer.json busco la configuración de grumphp y actualizo config-default-path de la siguiente manera: "grumphp": { "config-default-path": "grumphp.yml" } En el archivo grumphp.yml que hemos copiado a la raíz del proyecto buscamos la configuraciónde git_hook_variable y lo actualizamos de la siguiente manera: git_hook_variables: EXEC_GRUMPHP_COMMAND: ddev exec php Por último en la consola ejecuto el siguiente comando para actualizar la configuración del hook pre-commit ddev exec grumphp git:init De esta forma actualizaremos el hook pre-commit de nuestro proyecto (los hooks pre-commit están en la ruta '/.git/hooks/pre-commit`y el archivo queda así: `bash DIFF=$(git -c diff.mnemonicprefix=false -c diff.noprefix=false --no-pager diff -r -p -m -M --full-index --no-color --staged | cat) export GRUMPHP_GIT_WORKING_DIR="$(git rev-parse --show-toplevel)" (cd "./" && printf "%s\n" "${DIFF}" | ddev exec php 'vendor/bin/grumphp' 'git:pre-commit' '--skip-success-output') `  ( 3 min )
    Understanding the Builder Pattern – One Brick at a Time
    📘 Why This Blog? When I first encountered the Builder Design Pattern, it felt over-engineered—like too many classes just to build an object! clicked. This devblog is my honest take on helping you understand the Builder Pattern—the way I wish someone had explained it to me. The Builder Pattern helps construct complex objects step by step. In simple terms: You control the construction process, one method at a time. You might be looking at a Builder Pattern if you see: A class with many constructor parameters (some optional).

    React Compiler RC: What it means for React devs
    Written by David Omotayo✏️ The React compiler is one of the biggest updates to the React framework in years. Last year, the React team released a beta version. Around that time, I wrote an article called “Exploring React's Compiler: A Detailed Introduction”. It unpacked the core idea behind the compiler and showed how it could improve React development by automatically handling performance issues behind the scenes. When the beta dropped, the React team encouraged developers to try it out, give feedback, and contribute. And many did. A standout example is Sanity Studio. They used the compiler internally and shipped libraries like react-rx and @sanity/ui that are optimized for it. Thanks to contributions like these, the React team officially released the first Release Candidate (RC) on Apr…  ( 10 min )

    AWS Storage Explained: Choosing Between File, Block, and Object Storage Like a Pro
    Ever felt like you're drowning in data? You're not alone. In today's digital world, applications generate and consume information at an unprecedented rate. Choosing how and where to store that data in the cloud is one of the most fundamental – and often confusing – decisions architects and developers face. Pick the wrong type, and you could end up with slow performance, skyrocketing costs, or an architecture that just doesn't scale. You look at the AWS console, and the options seem endless: S3, EBS, EFS, FSx... what's the difference, and when should you use each? It feels a bit like walking into a massive hardware store looking for a screw – you know you need something to hold things together, but the sheer variety of options is overwhelming.

    A Look into CTags: The Secret Map of Your Codebase
    Have you ever opened a massive codebase and wished you could jump straight to the definition of a function, class, or variable without scrolling endlessly? That's exactly what CTags is for. In this post, we’ll break down what CTags is, how to use it, and—most importantly—how to read a tags file CTags (short for "C Tags") is a tool that scans your code and generates an index of where functions, variables, classes, and other identifiers are defined. This index is saved in a file called tags. Suppose you have this simple math_utils.py file: def add(a, b): return a + b def subtract(a, b): return a - b Run this in your terminal: ctags -R . You’ll now see a file called tags in your directory. tags File? Here’s what it might look like: add math_utils.py /^def add(a, b):$/;" f s…  ( 4 min )
    How to Detect Offline/Online Status in ReactJS
    Have you ever wanted to notify users when they lose internet connectivity in your React app? Today we build AppShell component together that monitors the browser's online/offline status and shows a user friendly message when the user goes offline. Realtime apps (like chat, stock tickers, etc.) depend on live connectivity. Offline-friendly experiences build trust and reliability. It's surprisingly easy to implement. Lets Wrap the entire app (or any major layout component) with AppShell: navigator.onLine: Detects the initial connection status. window.addEventListener("online"/"offline"): Reacts to changes in network status. useEffect: Registers and cleans up event listeners when the component mounts/unmounts. Let me know how you're handling offline states in your apps :)  ( 3 min )

    How to Dynamically Configure REST API URLs in Angular
    Introduction If you're new to Angular and transitioning from server-side development, one common challenge is configuring your application to dynamically connect to your Spring REST API. While hardcoding URLs might be the simplest immediate solution, it often causes issues when deploying to different environments. In this article, we will discuss various approaches to effectively manage API URLs in your Angular application, ensuring a smooth deployment process. Understanding API URL Management When building applications that interconnect with REST APIs, it's crucial to manage API URLs efficiently. Typically, during development, you'd use one server endpoint (localhost), while production might require a completely different URL. Hardcoding API endpoints makes it challenging to adapt to thes…  ( 5 min )
    Go #008 – Closures: Escape Analysis in Action
    Closures in Go are powerful but come with hidden memory implications.

The Code package main func counter() func() int { count := 0 // Escapes to heap (captured by closure) return func() int { count++ return count } } func main() { // Closure captures heap-allocated variable c := counter() println(c()) // 1 println(c()) // 2 // Loop closure pitfall var funcs []func() for i := 0; i < 3; i++ { funcs = append(funcs, func() { println(i) // i escapes to heap…  ( 4 min )

    How NoLogin Was Born: From a Computer Lab Frustration to a Sharing Revolution
    It all started back in 3rd sem — during one of my computer lab session. My friend had just executed his code — and it worked perfectly. So what happened? He had to log into Gmail on the lab PC That’s when I had this thought: Googled and found already existing ones like dontpad So, for the next couple of weeks, all of us started using dontpad — mostly just copy-pasting code, sharing it as soon as someone got it working. Whoever cracked the problem first would dump the code there, and the rest of us would just grab it and run. Then one day, I was sitting in class and noticed how our teacher logged into her Gmail just to download a PPT and present it to the class. That moment stuck in my mind — but I got busy with other things and didn’t think much of it. A few days later, one of our teachers…  ( 4 min )

    Bring third-party incidents into Better Stack
    Incidents in cloud and SaaS tools block users just as hard as faults in your own code. The fix comes faster when the same on-call queue covers both. IsDown now plugs straight into Better Stack through a native API connection. Every outage that IsDown detects shows up as an incident in Better Stack, follows your existing escalation rules, and clears automatically once the vendor recovers. Vendor downtime seldom triggers your own uptime probes—the traffic never reaches you. IsDown closes that gap by checking hundreds of official status pages round the clock. When those signals land inside Better Stack, responders work from a single incident list. No tab-hopping, no split workflows. A shared queue also tightens communication. Stakeholders follow one channel, post-mortems cover both internal a…  ( 4 min )
    When is it necessary to split a dataset for Analysis? Is it before, or after we clean the data? That is the question.
    ** ** What is data? Data, in its simplest form, is raw, unprocessed facts and figures. It can be numbers, text, images, or any other form of information that can be stored and processed by computers. Data becomes meaningful information when it is analyzed, interpreted, and placed in context. Therefore, Data is the basic unit of information before it's been organized, analyzed, or interpreted. What is information? In data science, splitting your dataset effectively is an important initial step towards building a robust model. Generally, you'll want to allocate a larger portion of your data for training, very often around 70%-80%, with the remaining 20%-30% for testing. This allows the model to learn from a substantial amount of data while still retaining enough unique data points to test …  ( 8 min )

    TS1436: Decorators must precede the name and all keywords of property declarations
    TS1436: Decorators must precede the name and all keywords of property declarations TypeScript is a robust, statically-typed programming language designed as a superset of JavaScript. Simply put, it enhances JavaScript by adding type definitions (a way to explicitly define the type of values) and other powerful features like interfaces, enums, and decorators. This makes it easier to work with larger codebases and prevent runtime errors by catching issues during the compile time. For those just starting out, think of TypeScript as a tool that adds structure and safety to JavaScript without changing its core nature. If you're building complex applications or working in a collaborative team, TypeScript helps make your code predictable, maintainable, and scalable. Type definitions form the c…  ( 6 min )

    Part 2 of Pattern Matching in Switch - Java
    This is the part 2 of the blog covering switch expressions in Java. If you haven't read part 1 yet, please give it a read here as it would cover some of the basic understanding of the switch expression and pattern matching in switch. Java compiler doesn't force exhaustiveness in switch statements, whereas switch expression are expected to be exhaustive. What really is exhaustiveness? Exhaustiveness ensures that all possible cases are handled in a switch expression, either explicitly or with a default case. For example, When you use an enum type, switch must cover different values of the enum. This is not limited to enums, its applicable to all the types switch supports.

    Dev Diary #1 – Google Agent Development Kit: Lessons I Learned
    This diary-tutorial hybrid tracks my first months with Google’s Agent Development Kit (ADK) — pure experience, insight sharing, and nothing else. The ADK is Google’s open-source framework for designing, chaining, and shipping autonomous AI agents. If you are unfamiliar with this framework, read my beginner guide to build AI agents quickly. You don’t need many AI agents, one for each task. An agent can call as many tools as it needs. AI independently decides what tool it should use and when. Write a precise prompt and correctly declare what tools AI can access and when it should be used. You should care what you save in the session state. AI agents could save the output to the session state, and different agents in your AI pipeline could access it. While developing, you should navigate to t…  ( 5 min )
    API Testing Essentials: What Every QA Engineer Should Know
    If your organization relies on software to deliver value, APIs are already at the epicenter of your digital infrastructure. They connect your systems, enabling you to scale through integration and automation and deliver superior customer experiences. But what’s often overlooked is that APIs are only as reliable as your ability to test them effectively. Unlike traditional UI testing, which focuses on the frontend layer, testing them gives you visibility into the actual mechanics of your app—the business logic, the rules that drive decisions, and the integrations that connect your systems. If you don’t validate that layer thoroughly, you leave core functionality exposed, increasing security risk. In this blog post, we’ll explore API testing in detail: its types, benefits, prerequisites, best…  ( 11 min )

Gemini Multimodality combines the capabilities of language models with image and document analysis, enabling AI to understand not just text, but images and other media within documents. The course introduced me to Multimodal RAG (Retrieval-Augmented Generation), a method that enhances AI’s ability to retrieve and generate information from multiple sources, making document inspection smarter and more efficient. Through this course, I learned how to apply these techniques for document parsing, intelligent search, and extracting insights from complex datasets. By integrating Gemini’s multimodal capabilities, I can now inspect and analyze rich documents, unlocking new possibilities in document automation, content generation, and knowledge extraction.  ( 3 min )
    Okay, it's time to change your cron job
    I'll start this post by saying that it's been a while since we got the first version of the CRON, which became de facto a default task scheduling tool for developers. Even more, cron jobs are older than me and I'm not that young. When I first got into software development, we used to deploy our code on EC2 instances and have a minimal continuous delivery setup realized via webhooks that triggered the git pull command and restart nginx, but we also had a bunch of recurring tasks That had to be invoked at midnight (classic example). Some of them had to run every couple of minutes. I remember learning the cron syntax at that time, it felt almost like RegExp, but surely, it was 1000 times easier, however, this is not what I want to talk about. Over time, a lot of tools that I used for softwar…  ( 7 min )
    Building Gen AI Apps with Gemini and Streamlit

    Optimizing Developer Workflows: Insights from Slack and AI Tools
    Originally published at ssojet Slack's Developer Experience (DevXP) team recently implemented significant optimizations to their end-to-end (E2E) testing pipeline, achieving a 60% reduction in frontend build frequency and a 50% decrease in overall build time. These enhancements streamline the continuous integration and deployment (CI/CD) process, allowing engineers to iterate rapidly and efficiently. Slack's existing repository utilizes a CI/CD pipeline that runs E2E tests prior to merging code into the main branch. This process validates changes across the entire application stack, including frontend, backend, and database. However, the team found that frontend builds occurred even when no frontend-related changes were made, leading to unnecessary long build times and resource consumptio…  ( 5 min )

    How to Fix Executable Path Issues in .NET Core 3 Single File Builds
    Introduction Upgrading an application to .NET Core 3 often brings a variety of enhancements, one of which is the option to publish a single-file executable. While this has its advantages, many developers encounter path-related issues during the build process, particularly related to the PublishSingleFile flag. This article addresses a common problem where the executable path defaults to a temporary directory, disrupting access to vital resources. Understanding the Issue When you set the PublishSingleFile flag, the .NET runtime modifies how executable paths are resolved. Instead of locating the executable file in its original directory, it often redirects to a location like /var/tmp/.net/. This behavior occurs due to the way the runtime handles unpacking the single-file executable at runtim…  ( 5 min )

    Exceptions in Java
    Exceptions in Java are events that disrupt the normal flow of a program's execution. They are used to handle errors and other exceptional events that may occur during runtime. Checked Exceptions (compile-time exceptions) Must be declared or handled (using try-catch or throws) Examples: IOException, SQLException, ClassNotFoundException Unchecked Exceptions (runtime exceptions) Not checked at compile time Examples: NullPointerException, ArrayIndexOutOfBoundsException, ArithmeticException Errors Serious problems that applications should not try to catch Examples: OutOfMemoryError, StackOverflowError Exception Handling Keywords try: Block of code to monitor for exceptions catch: Block that handles the exception finally: Block that always executes (for cleanup) throw: Used to explicitly throw an exception throws: Declares exceptions that might be thrown by a method try { // Code that might throw an exception int result = 10 / 0; // This will throw ArithmeticException } catch (ArithmeticException e) { System.out.println("Cannot divide by zero!"); } catch (Exception e) { System.out.println("General exception caught"); } finally { System.out.println("This will always execute"); } You can create your own exception classes by extending Exception (checked) or RuntimeException (unchecked): class MyCustomException extends Exception { public MyCustomException(String message) { super(message); } } Catch specific exceptions rather than general Exception Don't ignore caught exceptions (empty catch blocks) Use finally blocks for resource cleanup Document exceptions with @throws in JavaDoc Consider whether to handle, propagate, or convert exceptions Would you like more details on any specific aspect of Java exceptions?  ( 3 min )

    Import/Export: Default vs Named (And Why Some Use Braces)
    If you've worked with React or JavaScript modules, you might have noticed that sometimes you write imports with curly braces ({}) and sometimes without them. Ever wondered why? Let’s break it down. A default export allows a module to export a single value. It’s useful when your file exports just one main thing — like a component. // components/Footer.jsx export default function Footer() { return ...; } import Footer from './components/Footer'; 🚫 No curly braces needed for default exports. A named export allows you to export multiple values from a file. You must import them using curly braces. // components/Contact.tsx export function Contact() { ... } export function AnotherHelper() { ... } import { Contact } from './components/Contact'; ✅ Curly braces required for named exports. You can combine both in one file: export default function App() { ... } export function Helper() { ... } Then import like: import App, { Helper } from './App'; Hope this clears up the mystery behind those curly braces!

If it encounters any item that doesn’t it break the loop and returns false, however if all items satisfy the conditions then true is returned. However, there is a peculiar behavior to this method in that if an empty array is used then true is still returned. This is where the concept of vacuous truth comes in // typesc…  ( 4 min )

    Convertir un forEach con if a un Stream con filter en Java
    En el post anterior vimos cómo convertir un bucle for con incremento distinto de 1, y un bucle for infinito a un estilo completamente funcional utilizando el método iterate() de IntStream. En este post veremos como convertir un bucle foreach de un estilo imperativo a un estilo funcional, además de cómo filtrar elementos de acuerdo a una condición. En Java 5 se introdujo la sintaxis de foreach, la cual se utiliza para iterar sobre colecciones de elementos. Por ejemplo, para iterar una colección de cadenas que representan nombres, podemos escribir for(String name: names){}. En segundo plano, él foreach se convierte, a nivel de código de bytes, para utilizar un Iterator, mientras que el iterator nos dice que hay un elemento, busca el siguiente elemento para procesarlo. En otras palabras, él f…  ( 5 min )
    Logging in Spring Boot with SL4J
    Logging is a fundamental part of software development that provides insights into an application's behavior, making debugging and monitoring easier.

Monitoring & Observability: Logs allow teams to monitor application health and detect anomalies. Security Auditing: Logs keep records of critical events, such as user authentication attempts and database queries, which are essential for security audits. Performance Optimization: By analyzing logs, deve…  ( 5 min )
    So, Don't Overreact But... I'm So Over React
    More accurately, I’m over everyone treating it like the only answer. I'm a devout supporter of Web Components and have been preaching the gospel of W3C standards for decades. That guy you always hear muttering "Why use a library when the browser gives you everything you need?" I have lived through five versions of HTML (2,3,4,XHTML,5) and watched as libraries like jQuery and frameworks like Angular have come and gone from the spotlight. And I'm here now to tell you that you never NEEDED any of them and this has never been more true than it is today. Custom Elements, Shadow DOM, HTML Templates. These tools provide everything we need to build robust, modern apps without relying on heavy abstractions. But still, in 2025, the web development world clings tightly to libraries like React.

    What is Database Server?
    database server is a server which uses a database application that provides database services to other computer programs or to computers, as defined by the client–server model.[citation needed][1][2] Database management systems (DBMSs) frequently provide database-server functionality, and some database management systems (such as MySQL) rely exclusively on the client–server model for database access (while others, like SQLite, are meant for use as an embedded database). Users access a database server either through a "front end" running on the user's computer – which displays requested data – or through the "back end", which runs on the server and handles tasks such as data analysis and storage. In a master–slave model, database master servers are central and primary locations of data while database slave servers are synchronized backups of the master acting as proxies. Most database applications respond to a query language. Each database understands its query language and converts each submitted query to server-readable form and executes it to retrieve results. Examples of proprietary database applications include Oracle, IBM Db2, Informix, and Microsoft SQL Server. Examples of free software database applications include PostgreSQL; and under the GNU General Public Licence include Ingres and MySQL. Every server uses its own query logic and structure. The SQL (Structured Query Language) query language is more or less the same on all relational database applications. For clarification, a database server is simply a server that maintains services related to clients via database applications. DB-Engines lists over 300 DBMSs in its ranking.  ( 3 min )
    AWS Config vs Kubernetes Native Policy Engines: Who Governs What?
    In modern cloud-native environments, compliance, governance, and standardization are critical to ensuring security, operational efficiency, and regulatory adherence. As organizations adopt containerized infrastructure, enforcing consistent policies across platforms like Amazon EKS (Kubernetes-based) and ECS (serverless containers) becomes increasingly complex. At first glance, AWS Config and Kubernetes-native policy engines like OPA Gatekeeper and Kyverno may appear to serve the same function — enforcing rules and ensuring compliance in containerized workloads. But in reality, they operate at different layers, solve distinct problems, and target different scopes of governance. AWS Config is designed for cloud-wide compliance across AWS resources, whereas Kubernetes-native engines are focus…  ( 7 min )

    What is Data Mart?
    A data mart is a structure/access pattern specific to data warehouse environments. The data mart is a subset of the data warehouse that focuses on a specific business line, department, subject area, or team.[1] Whereas data warehouses have an enterprise-wide depth, the information in data marts pertains to a single department. In some deployments, each department or business unit is considered the owner of its data mart, including all the hardware, software, and data.[2] This enables each department to isolate the use, manipulation, and development of their data. In other deployments where conformed dimensions are used, this business unit ownership will not hold true for shared dimensions like customer, product, etc. Warehouses and data marts are built because the information in the datab…  ( 4 min )

    Is Big Data Dying?
    In recent years, the notion that “big data is dying” seems to be gaining traction. Some say the big data craze has faded, while others lament the shrinking job opportunities, the increasing complexity of platforms, and the growing intricacy of business demands. But does this really mean big data is dying? I don’t think so. In my view, what’s truly dying is not big data itself, but rather the outdated “dragon-slaying techniques” that no longer have any “dragons” to slay. The “dragon” has evolved, while our weapons remain stuck in the past. Technology needs to evolve, architectures need to be restructured, and capabilities need to be upgraded. To understand the current state and trends of big data, we must first examine how it has evolved step by step. The development of big data can be divi…  ( 8 min )

    Goodbye Spaghetti State: Query Objects Make React Filters Clean & Easy
    When you're building a dynamic frontend—like a game store, product listing, or job board—your UI needs to handle a lot of state: What page are we on? What filters are selected? Are we sorting by newest, most relevant, or trending? What platform, genre, or tags are selected? Managing all of that with separate useState hooks or deeply nested props can quickly become a nightmare. Enter the Query Object Pattern. A Query Object is a single JavaScript object that encapsulates all your query parameters—filter values, sort order, pagination, etc. const [query, setQuery] = useState({ genreId: null, platformId: null, sortOrder: 'relevance', searchText: '', page: 1, }); Instead of spreading your state across multiple hooks: const [genreId, setGenreId] = useState(null); const [platformId, s…  ( 4 min )
    The False Sense of Progress in learning
    When learning programming or data structures, it’s easy to feel like we're making significant progress just by spending a lot of time coding or watching tutorials. We might think that by solving numerous problems or watching endless videos, we are improving our skills. However, after a certain point, we might find ourselves struggling to solve problems we’ve encountered before or feel stuck when faced with new challenges. This is the false sense of progress that many learners experience in their programming journey. At the beginning of learning programming, it’s common to feel like we are advancing rapidly. Solving coding problems and watching tutorials can give us the impression that we're progressing. But when it comes to solving more complex problems or applying what we've learned to re…  ( 5 min )
    Virtual Machines vs. Containers: Unmasking Limitations and Celebrating Heroes
    Limitations of Virtual Machines and Servers? 1. Startup & Shutdown Times: VMs generally take longer to start up and shut down compared to containers, which can impact the speed of deployment and scaling. This delay can be a bottleneck in environments requiring rapid provisioning and de-provisioning of resources. 2. Dynamic Resource Allocation is Complex: VMs rely on hypervisors(such as VMware ESXi, Microsoft Hyper-V) to manage and allocate resources like CPU, memory and storage. This adds complexity because the hypervisor needs to handle various resource demands and ensure fare distribution. (Earlier we would need to Shutdown the VM for changing the allocated resources but now this can be done on a running instance as well but it still needs input/human intervention and its complex) Aut…  ( 4 min )

    📦 At Most Once, At Least Once, Exactly Once: What Do These Really Mean?
    message queues or event streaming platforms play a critical role in enabling this communication. But here's the key question: How reliably is a message delivered from sender to receiver? Let’s break down the three core delivery semantics you’ll encounter in real-world systems 👇 At-Most Once 🔹 Messages are delivered zero or one time No retries, so if something fails — the message is lost no guarantee of delivery 💡 Use case: Monitoring metrics, logs, or telemetry where occasional loss is acceptable. At-Least Once 🔹 Messages are never lost may be delivered multiple times deduplicate on the consumer side 💡 Use case: Order processing, notifications, analytics — where duplicates can be filtered or ignored. Exactly Once 🔹 Each message is delivered only once, no duplicates, no loss very hard to implement complexity, latency, and often performance trade-offs 💡 Use case: Financial transactions, trading systems, accounting — where idempotency is not supported and every operation must be precise. Choosing the right delivery guarantee isn’t just about tech — it’s about your use case and business priorities. a single duplicate message could cost thousands. 📌 Message Queue vs Event Streaming Platform? 🔹 Message Queues (like RabbitMQ, SQS): Focus on reliability and order for point-to-point communication. 🔹 Event Streaming Platforms (like Kafka, Pulsar): Optimized for broadcasting, storing, and replaying high-throughput event logs. Ideal for event-driven systems and real-time analytics. What’s your go-to strategy for delivery semantics in distributed systems? Let’s discuss in the comments 💬  ( 4 min )
    Hey Frontend Devs, Feeling Slowed Down by Your CMS?
    Let’s be honest. You've spent hours wrangling with bloated WordPress themes or waiting on backend fixes just to launch a simple page. Sound familiar? It’s not you. It’s the traditional CMS model. Let’s talk about why headless CMS is the quiet hero that’s helping frontend developers like you build faster and smarter. What Is a Headless CMS (And Why Should You Care)? In dev-speak: it’s a CMS without a front-end layer. In real talk: it gives you content via API and lets you build the frontend however you want. So instead of battling clunky plugins and rigid templates, you’re free to code with your favorite stack — React, Next.js, Vue, whatever. 1. Speed Boost with Modern Dev Tools Headless CMS platforms are made to play well with modern JavaScript. You can: Pull content via REST or GraphQL Use static site generators like Next.js for blazing performance Integrate easily with CI/CD workflows Translation? You ship faster — and with less backend drama. 2. Frontend Freedom = Faster Iteration No more begging backend devs to make a template change. With headless, you’re in full control of the UI/UX. Want to test a new layout or animation? Go for it. Your content comes clean and structured — so you can design and iterate freely. ## 3. Better Dev-Content Team Workflow They update copy. You build features. No blockers. 4. Scale Without Slowing Down Need to serve content across web, mobile, and IoT? No problem. You can scale globally, without rebuilding everything from scratch. Final Thought: Headless Is Built for How Developers Actually Work If you’re tired of waiting on legacy systems and want a faster, cleaner development experience, it might be time to switch. Want to See It in Action? Try a free headless CMS demo with Caisy. It’s built with developers in mind — lightning-fast, API-driven, and perfect for JS frameworks.  ( 4 min )

    My Go-To Toolkit: Top 10 Shadcn/ui Components I Rely On for Modern Web Development
    The landscape of frontend development is constantly evolving, especially when it comes to UI components.

    I built gitNull: A minimalist GitFlow CLI tool to save time and stay focused
    Hello Dev.to community! 👋 As a developer, I often found myself repeating the same Git commands over and over again during my workflow... So I built a small CLI tool called gitNull to make that easier! gitNull? A lightweight GitFlow helper written in Node.js. It automates common git actions like: gitNull start-feature gitNull finish-feature gitNull push – adds, commits and pushes in one command With a retro CLI look and some colorful feedback thanks to chalk and figlet. I love clean workflows, and I always wished Git had something a bit more guided. I didn’t want a full GUI — just a faster terminal flow. This is my first attempt at building a CLI tool, and I'm sharing it to get feedback and ideas from the community. Check it out on GitHub: https://github.com/faithreborn/gitnull Whether you're a CLI junkie, a GitFlow user, or someone who just hates typing long commands — I’d really appreciate if you give it a try and tell me what you think. ❤️ Any feedback, issues or PRs are welcome!

My editor of choice, neovim, provides no such benefits out of the box, requiring me to configure everything, install language plugins, code completion, myself. Vim and neovim are by far more powerful editors, but lacking the ease-of-use of VSCode, and easy discoverability of new features; I don't recommend beginners to use these.

    Understanding gRPC: The Power of Single Long-Lived Connection
    When using gRPC, one of its biggest advantages over traditional REST is the use of a single long-lived connection over HTTP/2. What does that mean? Unlike REST where every request opens a new connection, gRPC establishes one persistent connection between the client and the server. Through this connection, multiple messages can be exchanged — in both directions — without reopening it each time. Think of it like this: Imagine going to a restaurant. With REST, you’d have to enter and exit the restaurant every time you wanted to order something new. But with gRPC, you sit down once, and continue to place multiple orders and have conversations — all through that single session. Benefits of gRPC’s Long-Lived Connection: ✅ Reduced latency ✅ Real-time communication ✅ Efficient use of resources ✅ Bidirectional streaming supported Use Cases: Perfect for real-time apps like online games, chat systems, IoT devices, and microservice communications — where speed and efficiency matter most.  ( 3 min )
    Recurrent Neural Networks (RNNs): A Comprehensive Guide
    Introduction The concept of sequence modeling is fundamental to understanding RNNs. Many real-world problems involve sequences, where the order of elements carries significant meaning. For example, in language, the meaning of a sentence depends heavily on the order of the words. Similarly, in video analysis, the sequence of frames determines the action being performed. RNNs excel at capturing these dependencies, making them a powerful tool for a wide range of applications. The application of RNNs is prevalent in the field of deep learning. The history of RNNs is marked by continuous evolution. Early RNN architectures faced challenges like the vanishing gradient problem, which hindered their ability to learn long-range dependencies. However, innovations like Long Short-Term Memory (LSTM) …  ( 7 min )

    Synesthetic Data Interfaces: Turning Code into Color, Sound, and Touch
    What If You Could Feel Data? This amazing idea is becoming real through something called synesthetic data interfaces. That’s a big name, but it simply means using your senses—like hearing, sight, or touch—to understand data. It’s like turning code or information into a song, a rainbow, or even a feeling in your hand. Why is this important? Because everyone learns differently. Some people understand pictures better, while others learn better by hearing or touching things. Synesthetic data interfaces help people understand hard things in their own way. And guess what? It’s not just for learning. These tools can help doctors, scientists, game designers, and even artists see their work in a brand-new light. In this blog, we will go on a fun journey to learn how this new technology works, how i…  ( 8 min )

    Quark’s Outlines: Python Delimiters
    Overview, Historical Timeline, Problems & Solutions When you write Python code, you use symbols to separate, group, or define parts of the program. These symbols are called delimiters. A delimiter does not perform an action like an operator. Instead, it marks structure and boundaries. In writing, you use punctuation to make ideas clear. A comma breaks up items. A period ends a sentence. In Python, delimiters help the interpreter make sense of what comes next. Python uses delimiters to shape the structure of your code. (1 + 2) * 3 ['a', 'b', 'c'] {"key": "value"} x = 7 def f(): pass You use delimiters to build lists, assign values, pass arguments, and group code. Python requires these markers so it can read your program correctly. When you write a list, call a function, or create a diction…  ( 6 min )

    I Rebuilt My Personal Website with Eleventy — Here’s Why I Wanted It Simple
    jienweng.com Hi all. I recently rebuilt my personal site using 11ty, and I wanted to share a bit about why I chose simplicity over flashy design. Like many developers, I started with a more complex stack — Astro, React, lots of moving parts. It looked cool, but it started to feel like I was building for the tools instead of myself. So I started over with 11ty. It’s fast, flexible, and just lets me focus on content. Tbh I hate npm, and with 11ty i like that there's no bundlers, no frameworks. Just clean HTML, Markdown, and a bit of templating. The site is still a work in progress, but I like how it feels now — more personal, less performative. It’s a place for my notes, thoughts, and projects. Nothing fancy. Just mine. Would love any feedback or thoughts — especially from others who’ve simplified their stacks or gone the “digital garden” route. Thanks for reading!  ( 3 min )

    Modern Authentication Methods OAuth, JWT, and Beyond
    Authentication is at the heart of every secure web application. As frontend developers, understanding modern authentication flows and how to implement them securely is crucial. This article explores the most widely used authentication methods today: OAuth 2.0, JWT (JSON Web Tokens), and OpenID Connect, and introduces some emerging approaches. Authentication determines who the user is, and authorization determines what they can access. An insecure authentication mechanism can expose your app to session hijacking, data leaks, and impersonation attacks.

    There's Nothing Wrong With Coding Just to Pay the Bills
    I originally posted this post on my blog. I hate seeing "passionate" listed as a requirement in job postings. How can we measure passion? Is there a quiz, like those magazine questionnaires? "Find out if you're a passionate coder in less than 5 minutes with 10 easy-to-answer questions." The best coders I've met at past jobs weren't what we'd call passionate. By passionate, I mean making open source contributions, speaking at conferences, and writing posts. They were busy enough making money. The other day, Miguel, one of my email subscribers, shared a similar experience. Here's an excerpt of his email: Personally, I've become discouraged in my programming career and no longer aspire to work at one of the most important tech companies.

    How to Travel
    Pack your bags up the day before. Make sure to get the basics, underwear, socks, toothbrush, medications, pjs, travel documents, license, passport, – don't get deported, little gifts, etc... 'etc...'? This etcetera is the other stuff you forget and will inevitably have to purchase at your destination. Yes, I account for this because sometimes it doesn't matter how much time ahead I pack there is usually something I missed packing and have to either bother a relative to let me borrow it. I don't love forgetting stuff but at this point I rather forget than having to change my ways, like packing weeks before like my mother does. Smart lady, never forgets anything. I'm more like my dad in these type of things. 'Men'. I'm not sure if it's a fair thing to asume, 'all men are bad at packing' but I tell you, there is a pattern. My male cousin, doesn't travel, I wonder if he would also suck at packing. I think having a comfortable amount of money makes you care less because you can just purchase what you forget at the place where you go to maybe, – saying this in the most possibly humble way. For example, I forgot to pack belts, now I have to go to a store and buy something I already had for free at home.  ( 3 min )
    Messaging Made Simple with RabbitMQ-Stream
    A lightweight RabbitMQ framework for Node.js, built to eliminate boilerplate and let you focus on business logic. Let’s say you’re building an app with several moving parts—maybe one service processes user signups, another sends welcome emails, and another tracks analytics. Normally, these services would need to talk to each other directly and immediately—which makes things tightly connected and harder to scale. Messaging and event-driven architecture solve this by letting each part send and receive information independently. It works like this: When something important happens (like a new user signing up), that part of the app sends a message—think of it like dropping a letter in a mailbox. RabbitMQ. Here’s a simple example: A user signs up → The app sends a user.created message → The > e…  ( 6 min )
    How to Create a Fibonacci Sequence in JavaScript?
    Creating a Fibonacci sequence in JavaScript is a fascinating way to explore the world of programming and mathematics. The Fibonacci sequence is defined by the relation where each number is the sum of the two preceding numbers, starting from 0 and 1. In this article, we'll explore how to implement this sequence in JavaScript using a while loop, similar to the summation approach that you shared. Let's delve into writing an efficient script for generating Fibonacci numbers. Understanding the Fibonacci Sequence The Fibonacci sequence starts with 0 and 1, and every subsequent number is derived from the sum of the two previous numbers. A brief look at the series reveals: 0, 1, 1, 2, 3, 5, 8, 13, 21, ... This characteristic property makes it a popularly studied sequence in both mathematics and pr…  ( 5 min )

    🌀 The Ritual Scheduler
    “Summon a daily contribution. Maintain the illusion. Worship the green.” You ever stare at your GitHub contribution graph like it's a Tamagotchi you forgot to feed? Yeah, me too. So I built something unholy: A Bash-based automation daemon that ensures your GitHub profile always looks... alive. It commits. It pushes. It even wakes your computer from the dead to do it. ⏰ Schedules fake-but-believable commits at randomized human hours 🔁 Retries if GitHub rejects your offering 💾 Logs your ritual attempts and successes 🌴 Vacation mode, so your ritual pauses when you need rest (or alibis) 🔥 Self-healing if a ritual was missed (triggered by guilt and grep) 👁️ macOS popup warnings like: > “⚠️ No ritual detected today. The square is empty. You are exposed.” 🧙 Choose your commit incantations like: feat: added function nobody asked for fix: removed existential crisis from variable name 📜 Add custom altar messages 🔓 Unlock rare achievements like: "100 Days of Devotion" "The Sacred Streak" ✅ Daily ritual cron + safety check daemon 🪞 GitHub visibility flip (goes public, commits, hides again) 🧙‍♀️ Bash installer with prompt-based setup 🏕️ Vacation flag toggle for burnout mercy 🧾 .command launcher for double-click ritualism 🎨 Coming Soon: SVG badges GitHub profile theme pack Guilt Daemon™ (shames you in Slack when your squares go dark) Yes. I built it for fun. I also use it daily. It’s part spiritual theater, part productivity placebo, and part real automation. Bash cron, pmset, at, and osascript (macOS) GitHub CLI (gh) Dark magic I'm testing the waters. If enough devs want this, I’ll clean it up, ship a proper version, maybe even add a front-end GUI (Tauri? React? Electron? We’ll see). Leave a comment if you'd actually use it — or just want the GitHub link. “Coding is a ritual. This just makes it official.”  ( 4 min )
    Still lost in Voronoi Diagrams
    This is going to be a quick Devlog, because I just want to get back to this issue I'm having and figure out a solution for it. I've gone back to the drawing board, trying to figure out how to effectively unwrap the donut-shaped Voronoi diagram I have for my river tiles. I think this is the third week I've been working on the same problem now, so I'm getting a little frustrated because 3 weeks is a lot of time that could have been spent working on some other part of the game. I just feel like when I do solve this, one - I won't have to think about it again, and two - the visual pay-off will have been worth it. I also feel like I've invested too much time to not get some kind of pay-off for this feature. The biggest issue that I'm having is that when I have the shapes aligned as they leave one of the corner tiles and enter the straight tile, by the time they flow along the straight path in time to reach the bottom, they're not quite aligned. Now I think the problem I'm having is that I've got a slight overlap on the tiles, the row beneath covers the row above by a couple of pixels - enough to make the borders around the tiles match up. This looks fine in practice, but I need to compensate for that when aligning the shapes, and I feel like this is throwing a spanner in the works. So, I'm redoing my hex grid, and I'm using this article as a reference... https://www.redblobgames.com/grids/hexagons/ I'm going to try and math my way through this tonight. Wish me luck! Cheers, Dan.  ( 3 min )
    Import a large CSV more than 1G into a database quickly
    This article will introduce how to quickly import csv or txt files larger than 1g into the database. Here, we prepared a CSV file with 10 million rows x 30 columns x 4GB. At first, I tried to import it with Navicat. The first problem I encountered was that the encoding format was unknown, which led to many attempts to find the correct encoding. The second problem is that Navicat reads and writes one by one. Although this does not take up memory, the speed is very slow. The third problem is that halfway through the import, an error was reported because the field length was not enough! ! ! I had to reset the field length and import from 0 again. . . What's worse is that after setting one field, another error was reported. . . Now, we use the DiLu Converter Import tool to solve these problems one by one. Encoding: It can be automatically identified by default (for files with unknown encoding). If the encoding format of the file is known, you can select or enter its encoding format to speed up the parsing speed. Chunk Size: You can set the number of rows to import at a time according to the available memory of your computer. My computer has a total of 16G memory, about 9G is available, and 500,000 is set in a batch. Here, you must set the size according to the available memory. If the setting is too large, the memory may overflow, and if the setting is too small, it will not speed up. And The just click start You can see that it takes about 20 seconds to import a batch of 500,000 rows, and the memory usage is less than 1G Finally, it took about 5 minutes to import this csv file of 10 million rows x 30 columns x 4GB, and the maximum memory usage was about 1G. Because the tool imports files in batches according to batch size, no matter it is 1 file or hundreds or thousands of files, no matter a single file is 1G or 100G, as long as the batch size is set reasonably, it can be imported quickly, stably and without consuming memory.  ( 4 min )
    How to Create a Generic Structure with a Default Type in Rust?
    Creating generic structures in Rust can initially seem challenging, especially when it comes to default types. In this article, we will explore how to create a generic structure with a default type, allowing users to omit the generic parameter when defining instances. We’ll investigate why the Rust compiler requires explicit type annotations in certain situations and provide a step-by-step solution to this common problem. Why Does Rust Require Explicit Type Annotation? Rust is a statically typed language, which means types are known at compile time. When you define a generic structure, the compiler often needs to understand what specific type to use for the generics. In your code example, you're trying to instantiate C without specifying its type, which results in the following error: erro…  ( 4 min )
    🔁 1128. Number of Equivalent Domino Pairs – Explained with Code in C++, JavaScript, and Python
    If you’ve ever played with dominoes, you know that the order of the numbers doesn’t matter—[1,2] is the same as [2,1]. That's the central idea behind this popular LeetCode problem: 💡 Given a list of dominoes, return how many pairs of dominoes are equivalent. Two dominoes [a, b] and [c, d] are equivalent if: (a == c and b == d) or (a == d and b == c) Let's dive into the most optimal way to solve this! Instead of comparing every pair (which would take O(n²) time), we can: Normalize each domino: [a, b] becomes [min(a, b), max(a, b)] Use a hash map to count how many times each normalized domino appears. Every time we see a duplicate, we count how many previous identical dominoes we've seen. Add that count to the result (because every new domino can pair with all previous identical ones).

    # OpenSearch : 🚀 How to Improve Index and Shard Performance in OpenSearch
    OpenSearch, a powerful distributed search and analytics engine, offers high scalability and near real-time search capabilities. However, as data volume and query complexity grow, performance bottlenecks often emerge—particularly around indices and shards. This guide breaks down actionable strategies to optimize indexing, querying, and shard management for improved performance and cluster health. Index: A logical namespace that maps to one or more physical shards. Shard: A basic unit of storage and search in OpenSearch. Each shard is a Lucene index. Performance is tightly tied to how indices and shards are structured, distributed, and queried. Too many shards create overhead; too few limit concurrency. Aim for ideal shard sizes between 10–50 GB. Avoid the default 5 shards unless justified. …  ( 4 min )

    New York district gets interim US Attorney as ex-SafeMoon CEO trial kicks off
    Acting US Attorney for the Eastern District of New York (EDNY) John Durham has departed as President Donald Trump’s pick takes control of the office. In a May 5 notice, the US Attorney’s Office for EDNY said Joseph Nocella will serve as interim US Attorney for the region for 120 days or until a Senate-confirmed nominee assumes the role. Nocella’s appointment came as jury selection began in the criminal trial of Braden John Karony, the former CEO of crypto firm SafeMoon. It’s unclear how the advancement of Nocella, appointed by US President Donald Trump this month, could affect prosecutors’ case against Karony, who faces charges of securities fraud conspiracy, wire fraud conspiracy, and money laundering conspiracy. Nocella said he intended to help prosecute “narcotics-traffickers, gang memb…
    OpenAI to stay nonprofit, scrap proposed overhaul
    ChatGPT-maker OpenAI has abandoned plans to become a for-profit company and reaffirmed commitment to its nonprofit status.  In a May 5 blog post, OpenAI confirmed plans to convert its for-profit business unit into a so-called Public Benefit Corporation (PBC), which would remain under the nonprofit’s control. PBCs are for-profit companies that are legally obligated to prioritize a social mission alongside the interests of shareholders. The plans mark a reversal for OpenAI, which had previously floated a for-profit conversion involving spinning out the nonprofit entity. “OpenAI was founded as a nonprofit, and is today overseen and controlled by that nonprofit. Going forward, it will continue to be overseen and controlled by that nonprofit,” the ChatGPT-maker said.  This can be done without…
    Good actors were 'unfairly targeted' by SEC — OpenSea's CEO
    The Securities and Exchange Commission’s (SEC) enforcement approach on crypto firms has left a lasting “regulatory overhang” within the industry, according to Devin Finzer, co-founder and CEO of OpenSea.  Speaking to Cointelegraph, Finzer said that during Biden's administration the agency unfairly targeted good actors in the crypto space, including OpenSea. “There's all sorts of digital assets, you know, you shouldn't treat them all the same. That's obvious. But I think the approach that the prior SEC was taking was kind of this, you know, very, very generic.” The SEC issued a Wells notice — a formal notification that is often a precursor to enforcement action — to OpenSea in 2024, alleging that the NFT marketplace was operating as an exchange for unregistered securities. At the time, Finz…

    Price predictions 5/5: SPX, DXY, BTC, ETH, XRP, BNB, SOL, DOGE, ADA, SUI
    Key points: Bitcoin is witnessing a tough battle between the bulls and the bears at the $95,000 level. Solid buying by spot Bitcoin ETF investors last week signals a positive shift in investor sentiment.  Select altcoins have held their support levels, increasing the likelihood of a short-term up move. Bitcoin (BTC) slipped below the breakout level of $95,000 on May 4, indicating profit booking at higher levels.

    Crypto market manipulation schemes are becoming increasingly coordinated
    Opinion by: Tracy Jin, Chief Operating Officer, MEXC Market manipulation is everywhere and yet nowhere to be seen. It is an invisible threat affecting crypto and traditional markets, leaving ordinary traders counting the costs. Sometimes, manipulation is obvious — illiquid tokens being pumped high before being dumped just as fast — but often, it's subtler and more challenging to detect. What's more concerning is that these schemes are no longer the domain of rogue whales or amateur pump groups. Signs increasingly point to highly organized, well-funded networks coordinating activities across centralized exchanges, derivatives platforms, and onchain ecosystems. As these actors grow in sophistication, their threat to market integrity expands exponentially. A tale as old as time  Market manipu…
    Ripple commits $25M US school nonprofits
    Ripple, the US-based crypto services firm behind the XRP Ledger, has committed $25 million in Ripple USD (RLUSD) to education nonprofits DonorsChoose and Teach For America. According to a May 5 announcement, the grant will be processed through the crypto charity intermediary service The Giving Block. DonorsChoose CEO Alix Guerrier said "teachers are going the extra mile for their students' education, even spending hundreds — sometimes thousands — of dollars out-of-pocket for their classrooms." The donations are meant to provide teachers with resources for such initiatives. Ripple cites a 2024 Gallup survey showing that 55% of US parents and adults are dissatisfied with the quality of K-12 education in the United States. This highlights “constraints and gaps in funding for education,” the reports reads. Ripple CEO Brad Garlinghouse said in the statement: “We hope to inspire others to do the same, starting with Teacher Appreciation Week, and leading into the rest of the year to support students and teachers with the resources they need to build a stronger future for themselves and their communities.” Teach For America CEO Aneesh Sohoni said the new funding will allow the organization to expand its “Ignite Tutoring Fellows program, drive innovation in our Reinvention Lab, and provide crucial financial assistance” to prepare teachers.

    XRP price risks 45% decline to $1.20 — Here is why
    Key takeaways: XRP forms a bearish descending triangle on the daily chart, risking a 45% drop to $1.20. Declining daily active addresses signal reduced transaction activity and liquidity. A breakout above $2.18 could invalidate the bearish pattern. The XRP (XRP) price flashes warning signs as a bearish technical pattern emerges on its daily chart, coinciding with declining network activity.  XRP descending triangle hints at 45% price drop The XRP price chart has been forming a descending triangle pattern on its daily chart since its late 2024 rally, characterized by a flat support level and a downward-sloping resistance line. A descending triangle chart pattern that forms after a strong uptrend is seen as a bearish reversal indicator. As a rule, the setup resolves when the price breaks…
    Crypto funds raked in $2B last week, pushing 3-week haul to $5.5B
    Cryptocurrency investment products attracted $2 billion in new inflows last week, according to the European investment firm CoinShares. Global crypto exchange-traded products (ETPs) have added $5.5 billion in inflows in the past three weeks, according to the latest weekly report from CoinShares.

Inflows slowed down despite new Bitcoin gains The slowdown in crypto ETP inflows came despite Bitcoin (BTC) seeing some brief gains last week, with the price rising from …
    Aptos exec sees Web 2.5 platforms earning ‘tons’ of revenue
    While many crypto ecosystems focus on decentralization as the core tenet of Web3, Aptos is seeing success with hybrid platforms that blend Web2 and Web3 technologies, commonly referred to as “Web2.5.” In an interview at the Token20249 event in Dubai, Aptos’ head of ecosystem, Ash Pampati, told Cointelegraph that they see Web2.5 platforms earn “tons of revenue” within Aptos. He noted that consumer-focused applications in particular are thriving on the network. Web2.5 is a term used to describe a combination of Web2 and Web3 technologies. The term describes platforms or applications that blend centralized Web2 experiences with decentralized Web3 elements.  These applications often avoid full decentralization, drawing criticism for not fully embracing the Web3 vision. Ash Pampati at the Tok…

    Tether AI platform to support Bitcoin and USDT payments, CEO says
    Tether AI, the forthcoming artificial intelligence platform from stablecoin giant Tether, will feature payments in major cryptocurrencies, including USDt and Bitcoin. Tether CEO Paolo Adroino took to X on May 5 to tease the imminent launch of Tether AI, the company’s new AI platform designed to offer “personal infinite intelligence.” According to Ardoino, Tether’s AI platform will be integrated with USDt (USDT) and Bitcoin (BTC) payments, allowing users to make transactions directly through a peer-to-peer (P2P) network.

    Vitalik Buterin says rollups must prove security before decentralizing
    Ethereum co-founder Vitalik Buterin has explained when he believes rollup-based layer-2 platforms should go decentralized, and why “as soon as possible” is not the correct answer. In a May 5 X post, Buterin explained that there is a right time for rollup-based scalability solutions to transition to a decentralized model. This moment depends on how low the proof system’s failure probability has fallen compared with the risks introduced by centralization. Buterin’s thread came in response to a separate post by decentralized exchange Loopring founder and CEO Daniel Wang. Wang explained in his thread that the maturity of a system matters to its security: “Not all code is created equal. A rollup can be Stage 2, but running fresh code that’s never been tested under real stress.“ Rollup developme…
    America’s crypto renaissance is already failing; but we can fix it
    Opinion by: Shane Molidor, Founder, Forgd For years, launching a crypto project in the United States has been a maze of uncertainty. Legal ambiguity and a hostile regulatory environment have driven founders offshore, turning places like Switzerland and the Cayman Islands into global hubs for blockchain innovation.  With Trump’s election, things finally started to change, with a US administration openly declaring its intention to be crypto-friendly. Yet, despite the rhetoric, nothing concrete has changed so far. Launching a crypto project in the US is just as difficult as ever. US regulatory agencies continue to offer nothing but vague threats and “regulation by enforcement” lawsuits. America wants to be a leader in crypto, but, even under the Trump administration, it isn’t taking action to…

    Notcoin says tap-to-earn ‘probably dead’ as Telegram games see shift
    Notcoin, one of the most prominent Web3 gaming projects of 2024, said the tap-to-earn genre is “probably dead” as Web3 gaming shifts to more fun and engaging projects. During Token2049 in Dubai, Notcoin co-founders Sasha and Vladimir Plotvinov, along with Uliana Salo, the head of design and product lead for NotGames, spoke with Cointelegraph about the state of Telegram-based Web3 gaming.  Vladimir told Cointelegraph that game builders are shifting to different genres as tap-to-earn has failed to sustain players’ interests.  “We’re going to see different types of games, as tap-to-earn games are probably dead because they’re not sustainable,” he said.  Notcoin’s Sasha Plotvinov (left), Uliana Salo (middle) and Vladimir Plotvinov (right) at the Token2049 event in Dubai.

    How cybercriminals are exploiting digital twins to scam crypto users
    What is a digital twin? A digital twin is a virtual model or replica of a physical object, system or process. It’s like a digital mirror, allowing us to simulate, monitor and predict the behavior of real-world entities in real-time.  These virtual counterparts are designed to pull data from physical sensors or inputs, providing a continuous feedback loop that helps with analysis, optimization and decision-making. Digital twins can represent almost anything, from machinery in a manufacturing plant to human behavior or entire cities. In industries like healthcare, automotive, manufacturing and urban planning, digital twins allow for better resource management, predictive maintenance and more accurate simulations before physical changes are made. In e…
    Stablecoin fever: 5 major stablecoins are growing crypto adoption
    Increasing institutional interest and moves toward legal frameworks for stablecoins have seen the space grow, with five major projects slated to expand the market in the near future. In the EU, the Markets in Crypto-Assets (MiCA) regulatory package is in full force and has given stablecoin issuers clear guidelines by which they can enter European markets. In the US, the STABLE Act and the GENIUS Act, which would provide rules for stablecoins, are making their way through Congress.  As a result, major payments firms like Mastercard and Visa are stepping up support for stablecoin systems, and new coins have appeared, boosting the overall market capitalization of the stablecoin market.  Here are five major stablecoin initiatives projected to grow crypto adoption.

    BTC dominance due 'collapse' at 71%: 5 things to know in Bitcoin this week
    Bitcoin (BTC) starts the first full week of May with yearly open support in focus ahead of a key US economic policy decision. BTC price action attempts to hold the yearly open as support after some downside at the weekly close, but bullish perspectives remain intact. The US Federal Reserve interest rate decision is the key macro event of the week, with Chair Jerome Powell tipped to “move markets.” Jobless claims and Coinbase earnings add to a mixed bag of potential volatility triggers as recession talk gets louder.

    Donald Trump gives conflicting answers over memecoin profits
    US President Donald Trump gave clashing answers to whether he has profited from the crypto memecoin he launched in January, just days before he re-entered the White House. In a wide-ranging interview with Kristen Welker on NBC News’ Meet the Press released on May 4, Trump said he was “not profiting from anything” when asked to respond to critics who said he’s profiting from the presidency through the memecoin. “So you’re not profiting off of the cryptocurrency at all?” Welker asked Trump. “I haven’t even looked,” Trump admitted. “But I’ll tell you what. Look, if I own stock in something and I do a good job, and the stock market goes up, I guess I’m profiting.” Trump launched his memecoin, Official Trump (TRUMP), on Jan. 17, which hit a peak of $73.43 two days later, just a day before he wa…
    OKX to restart DEX with anti-abuse upgrades after Lazarus ‘misuse’
    Crypto exchange OKX has brought its decentralized exchange (DEX) aggregator back online with new security upgrades after it was paused in March to prevent further misuse by the North Korean hacking crew, the Lazarus Group. OKX founder and CEO Star Xu said in a May 4 statement to X that the DEX aggregator, OKX Web3, will resume with several new features, including a “real-time abuse detecting and blocking system.” A DEX aggregator is a service that pulls data from multiple decentralized exchanges and market makers and then presents it to users to assist with trading.

    Bitcoin pioneer and felon says he’s ‘vibe coding’ to restart the BTC faucet
    Early Bitcoin entrepreneur Charlie Shrem says he’s working on bringing back the Bitcoin faucet — a website that hands out Bitcoin to whoever solves CAPTCHA tasks, normally used to distinguish humans from machines. Shrem shared his new Bitcoin (BTC) faucet website — 21million.com — in a May 4 X post, which mimics the first-ever Bitcoin CAPTCHA page created by early Bitcoin innovator Gavin Andresen back in 2010. The 21million.com website currently displays a screenshot of a CAPTCHA task and a box to enter a receiving Bitcoin address, which was not functional at the time of writing.  Shrem’s Bitcoin faucet website also shows that there are 0 Bitcoin available to claim.

    Industry calls for urgent crypto law reforms after Australian election
    The Australian crypto industry has called on the newly reelected Labor government to urgently make digital asset legislation a top priority to ensure Australia doesn’t fall further behind global markets. The incumbent Australian Labor Party was returned in a landslide on May 3, picking up 54.9% of the two-party-preferred vote, against the Liberal and National Parties on 45.1%. Both parties went to the election promising crypto law reform, but only the opposition pledged to deliver draft legislation within 100 days. Joy Lam, Binance’s head of global regulatory and APAC legal, said the exchange has been consulting with Treasury officials since late 2023 about its proposed legislation, and it was now time for action. “Timing is really quite critical now because obviously it's something that …
    US Bitcoin ETFs bought 6x more than BTC miners produced last week
    Spot Bitcoin exchange-traded funds (ETFs) in the United States bought up nearly six times as many Bitcoin as were produced by miners over the last week. The US-based Bitcoin (BTC) funds bought a whopping 18,644 Bitcoin over the past week when only 3,150 BTC were mined for the period, reported asset allocator HODL15Capital on May 4. This accumulation by institutions and ETF issuers represents almost six times the amount of the asset being produced since miners only generate 450 coins per day.   The total inflow for the past five trading days was around $1.8 billion, with a net outflow on April 30, according to Farside Investors. There has only been one outflow day since April 16, as the inflows have mirrored market recovery.  Last week’s accumulation followed an increase in BTC spot prices …
    OpenAI ignored experts when it released overly agreeable ChatGPT
    OpenAI says it ignored the concerns of its expert testers when it rolled out an update to its flagship ChatGPT artificial intelligence model that made it excessively agreeable. The company released an update to its GPT‑4o model on April 25 that made it “noticeably more sycophantic,” which it then rolled back three days later due to safety concerns, OpenAI said in a May 2 postmortem blog post. The ChatGPT maker said its new models undergo safety and behavior checks, and its “internal experts spend significant time interacting with each new model before launch,” meant to catch issues missed by other tests. During the latest model’s review process before it went public, OpenAI said that “some expert testers had indicated that the model’s behavior ‘felt’ slightly off” but decided to launch “du…
    Hackers use New York Post’s X account to send scam DMs, users report
    Malicious actors appear to have infiltrated the New York Post’s X account in an attempt to scam crypto users on the microblogging platform.  Some X users from the crypto community have recently reported having received a private message from the New York Post’s X account inviting them to feature in a podcast and to contact them via Telegram.  The spurious messages were first discovered on May 3 by Kerberus founder and CEO Alex Katz, who shared a screenshot of a message made out to be from author and journalist Paul Sperry via the official nypost account.  “What’s interesting about this case is that the scammer gained unauthorized access but didn’t post a Pump.fun address or wallet drainer. Instead, they’re messaging users and then directing them to Telegram,” observed cybersecurity enginee…
    Solana devs fix bug that allowed unlimited minting of certain tokens
    The Solana Foundation has confirmed that a zero-day vulnerability that allowed an attacker to potentially mint certain tokens and even withdraw those tokens from user accounts has been fixed.  A May 3 post-mortem from the Solana Foundation said that the security vulnerability, first discovered on April 16, could have allowed an attacker to forge an invalid proof affecting Solana’s privacy-enabling “Token-22 confidential tokens.” There is no known exploit of the vulnerability, and Solana validators have since adopted the patched version, the foundation said. Solana zero-day security bug affected Token-22 confidential tokens The Solana Foundation said the security vulnerability concerned two programs: Token-2022 and ZK ElGamal Proof.

    Mattel to wind down its Hot Wheels Virtual Garage NFTs
    Toymaking giant Mattel is putting the brakes on its Hot Wheels Virtual Garage non-fungible tokens, pending a decision on the collection’s future. There will be no future releases of any new NFT series or feature drops for the “foreseeable future,” Mattel said in an update on its website. The company said it will decide on the “long-term future” of Mattel digital collectibles. “Your unwavering support and enthusiasm for the Hot Wheels Virtual Garage has been legendary, and we’re incredibly grateful to have been on this journey with you,” the company said. “As we evaluate the changing world of virtual collectibles, we’ve determined the time has come to end our Series and Feature Drops in 2025 and onward.” There are no plans for any new NFT series or feature drops for Mattel's Hot Wheels Virt…
    Bitcoin price cools going into Fed rate hike week, HYPE, AAVE, RNDR, FET still look bullish
    Key points: Bitcoin’s positive sentiment should remain intact if BTC price stays above the 20-day EMA near $92,000. Several altcoins show bullish chart patterns in the 4-hour and 1-day timeframes. Bitcoin (BTC) has given back some of the gains over the weekend, and the price has pulled back to the breakout level of $95,000. Buyers will have to successfully hold the $95,000 level to keep the bullish momentum intact. Bitcoin network economist Timothy Peterson said in a post on X that Bitcoin could surge to a new all-time high and reach a target of $135,000 in the next 100 days if certain conditions are met. Peterson believes a drop in the CBOE Volatility Index below 18 could trigger a “risk-on environment” favoring Bitcoin. The other crucial points needed for the Bitcoin rally are a fall …

    Rethinking Tech Interviews: Real Skills, Real Projects, No Bullshit
    Introduction Let’s be honest — most software engineering interviews suck. They’re filled with algorithmic trivia, abstract whiteboarding, and awkward “culture fit” questions that have nothing to do with the actual job. The result?

    📝 3 Ways to Keep Your GitHub Active Without Burning Out
    _Spoiler: Only one of them involves actual effort Between burnout, client work, and staring blankly at VS Code for hours — keeping your GitHub streak alive can feel like a second unpaid job. I used to obsess over my GitHub activity like it was a Tamagotchi that needed daily care. Miss a day? Anxiety. Miss two? Shame spiral. But after years of freelance chaos and working in private repos no one can see, I realized something: I was doing real work... and still looking inactive. That green grid didn’t reflect my grind. So here are 3 ways I’ve learned to keep my GitHub looking alive — without coding every single day like a productivity martyr. One of the most common mistakes devs make is trying to force daily pushes just to fill the grid. Instead: Work in blocks. Real coding happens in spri…  ( 4 min )

    Rebuilt in 3 Days: DMs Are Back — and Better Than Ever
    Originally posted on May 2, 2025 After a major setback wiped our codebase, we rebuilt Tavrn's 1-to-1 DM system from scratch — in just 3 days. This post breaks down how we did it, what’s new, and why it’s already better than before. After losing our original codebase, we had two choices: Start over slowly and mourn the loss... Or hit the ground running and build something better. We chose the second one. It only took 3 days — but our 1-to-1 messaging system is back. Fully rebuilt from the ground up. Clean. Fast. Future-proof. And, honestly? It’s better than what we had before. We redesigned how messages move, how conversations flow, and how it all scales. What used to feel basic now feels tight — like something you’ll actually want to use every day. Here’s a little peek at what’s already working in our new DM system: 🔒 Fast messaging with improved delivery speeds 🌙 Sleeker UI built with clarity and vibe in mind 🗂️ Better message rendering 💬 Typing indicators and presence detection, redone the right way ⚡️ A system that can grow without getting messy And we’re just getting started. Now that DMs are locked in, we’re moving on to polish other core features — including group chats, profiles, and real-time updates. Every step is built with community, performance, and personality in mind. No bloat. No noise. Just smooth, satisfying conversation. Setbacks happen. But we’re proud of how we responded: By building. By improving. By actually shipping something better. If you’ve been waiting on Tavrn — thank you. The foundation is back. And the future’s right behind it. — Tavrn  ( 3 min )
    Intelligent Retail
    Shopping—a timeless ritual familiar to us all—is quietly undergoing a profound transformation. Gone are the days when shopping was nothing more than exchanging goods for currency. Today, beneath the familiar surface of the high street and online storefronts, an intricate interplay of data-driven intelligence and personalised precision shapes the retail landscape. At the epicentre of this quiet upheaval is Artificial Intelligence (AI). Not a futuristic novelty from distant sci-fi narratives, but a living, evolving presence within retail operations worldwide. By 2025, AI’s role in retail is forecasted to be valued at an astounding £54.92 billion. A recent Gartner report underscores its importance starkly: 91% of retail IT leaders now regard AI as a core strategic priority. AI, it seems, has …  ( 6 min )
    Agendas lead to more productive meetings
    I have been in team meetings where, they were basically, "free-form discussions." We'd start with good intentions, but two hours later, no real decisions have been made. It was frustrating, and the team's energy was draining with each meeting. The problem? We needed structure, not just good intentions. So, we started implementing detailed agendas for every meeting. At first, it felt a bit rigid, but then with time, our two-hour meetings actually ended in 45 minutes or less. People came prepared. Decisions were made faster. But here's the thing - it's not just about having an agenda. It's about crafting one that guides the conversation without stifling creativity. We found a balance between structure and flexibility with Rally. This experience played a huge role in why you can build agendas from your Jira board with Rally. How do you structure your team meetings? Have you found any agenda hacks that work particularly well? (👀🟣) I'd love to hear your thoughts.  ( 3 min )

    Does Your Coding Machine's OS Really Matter? My Windows-to-Linux Journey
    As someone who jumped from Windows to Linux, I've found that your choice of operating system can definitely impact your coding life - but it's not make-or-break. Linux gives me a better command line, simpler software installation, and runs lighter on my hardware. I especially love how it matches most production servers, making deployment way less headache-inducing. That said, Windows isn't the villain some developers make it out to be. It plays nicer with commercial software, gaming tools, and corporate systems. Windows users now have a solid option with WSL (Windows Subsystem for Linux), letting you run Linux tools right inside Windows - giving you the best of both worlds without the commitment of switching entirely. Ultimately, great developers build amazing stuff on all systems. Your OS is just one piece of your toolkit, not the defining factor of your skills. My switch to Linux boosted my workflow for web and backend projects, but I know plenty of rockstar devs crushing it on Windows and Mac. What's your setup?

    Why Does Using '==' Cause an Error in Kotlin with ExitStatus?
    In Kotlin, it’s common to encounter various types of comparison errors, especially when dealing with Java classes due to interoperability issues. The issue you're experiencing occurs when trying to compare an instance of the ExitStatus class from Spring Batch using the ==</code operator. Understanding the Comparison in Kotlin Kotlin has a distinct approach to equality compared to Java. In Kotlin, the == operator is actually syntactic sugar for the equals() method. Thus, when you write if (jobExecution.exitStatus == ExitStatus.COMPLETED), Kotlin attempts to call equals() on the jobExecution.exitStatus. However, if Kotlin does not recognize ExitStatus as having a valid equals method that matches the expected types, you will receive the compilation error: No method 'equals(Any?): Boolean' av…  ( 4 min )

This is a short story about a seemingly harmless line in a PR that I reviewed - and how it taught me to slow down, even with small changes. The line of code below, if(!user.isVerified) return; intention behind this was good not to allow unverified users to proceed into the app. But this return statement wasn't part of larger flow. It was inside a route guard - and it exited silently, without a redirect, message or error. User who signed up with Google or Github (OAuth) were marked isVerified=false This line caused the app to fail to load the protected dashboard, but displayed no error The app just failed silently with blank screen to user.

    What Is the Difference Between PHP Echo and Print in 2025?
    As we venture into 2025, PHP continues to be a foundational technology for web development. A common point of confusion among new developers is the difference between the echo and print statements in PHP. Understanding these differences is essential for optimizing your PHP code for performance and readability. echo vs print: An Overview Both echo and print are language constructs in PHP that are used to output data to the screen. While they may seem interchangeable, there are subtle differences: Syntax and Efficiency: echo can accept multiple parameters, whereas print can only take one argument. echo is slightly faster as it doesn’t return any value, allowing for better performance in large-scale applications. Return Values: echo does not return any value. print, on the other hand, alw…  ( 4 min )

    Orka: A Manifesto for transparent Intelligence
    ⚠️ The Problem: AI Workflows Are Broken Let’s be honest. Most AI projects right now are duct-taped chains of: Prompt injections Tool wrappers Hidden state Zero traceability And god help you if something breaks. You run your LLM call and hope it works. No visibility. No logic. No composability. It's brittle. It’s opaque. And it's slowing real progress. I didn’t want to “wrap” LLMs. I wanted to compose cognition. That means: ✅ Declarative logic (YAML, not code spaghetti) ✅ Modular agent types (search, classify, validate, build, etc.) ✅ Dynamic flow control (forks, joins, routers) ✅ Real-time introspection (Redis/Kafka logs) ✅ Reusable, testable reasoning blocks ✅ Full execution replay So I built OrKa: A composable orchestration framework for LLM-powered agents, built on YAML, Redis, an…  ( 4 min )

    Supercharging Language Models: What I Learned Testing LLMs with Tools
    LLMs are great at creative writing and language tasks, but they often stumble on basic knowledge retrieval and math. Popular tests like counting r's in "strawberry" or doing simple arithmetic often trip them up. This is where tools come into the picture. Simply put, we're giving LLMs capabilities they don't naturally have, helping them deliver better answers. I ran some tests with local models on Ollama and noticed some interesting patterns: I tested various models with this straightforward financial question: "I have initially 100 USD in an account that gives 3.42% interest/year for the first 2 years then switches to a 3% interest/year. How much will I have after 5 years?" The correct answer is 100 * 1.0342^2 * 1.03^3 = 116.8747624. What surprised me was that top models like Gemini 2.5 Pr…  ( 5 min )

    How to Use Reference and Output Parameters in Java
    Introduction In programming, passing parameters to functions is crucial for manipulating data effectively. Java, unlike some languages such as C#, does not support reference parameters in the same way. Instead, Java uses pass-by-value semantics, which means that when you pass a variable to a method, a copy of that variable is sent. However, there are ways to achieve similar functionality using mutable objects or wrapper classes. In this article, we'll explore how to simulate reference-like behavior in Java using simple examples and provide a clear understanding of handling output parameters in functions. Understanding Reference Parameters in Java When you define a method parameter in Java, it typically receives a copy of the variable's value. If you want to modify the value of an object re…  ( 5 min )

    What does (*jsontext.Value)(&b).Indent() do in Go?
    When working with Go, handling JSON data is a common task. In the code snippet you're referring to, we see the use of a specific method: (*jsontext.Value)(&b).Indent(). This can be a bit confusing for those who are new to Go or JSON manipulation. So let’s break it down. Understanding JSON Marshaling in Go In Go, the encoding/json package is typically used to encode and decode JSON. In your example, b, _ := json.Marshal(output) marshals the output variable into a JSON byte slice b. The underscore _ is used to ignore any errors that may occur during marshaling. This is often a pattern when we are confident that there won't be an error or we want to handle it later. What is *jsontext.Value? The section (*jsontext.Value)(&b).Indent() involves a couple of key components. First, jsontext.Value i…  ( 4 min )

    Debugging @Scheduled Tasks in Spring Boot Without Sending Harassing Emails
    Recently in enterprise development, I came across a requirement to adjust and optimize a scheduled email-sending task. While the logic itself was straightforward, the debugging experience was not. Here's what made it tricky: The development environment lacks a unified interface to manually trigger backend @Scheduled tasks from the frontend. Debugging by modifying the cron expression means: Restarting the entire project every time Risking a flood of unintended emails While test code can directly invoke methods, it's not always clean or convenient. Let’s look at the scheduled task: @Component public class EmailScheduled { @Scheduled(cron = "0 0 23 * * * ?") public void emailSend() { // Actual email sending logic } } afterPropertiesSet to Trigger the Task The idea is simple: leverage the InitializingBean interface. Spring will automatically call afterPropertiesSet() when initializing a bean. So we can invoke emailSend() there to simulate a scheduled run. @Component public class EmailScheduled implements InitializingBean { @Scheduled(cron = "0 0 23 * * * ?") public void emailSend() { // Actual email sending logic } @Override public void afterPropertiesSet() throws Exception { emailSend(); // Triggered once at startup } } No cron modification No project restart just to adjust time No actual scheduling triggered — just one-time manual invocation Perfect for short-term debugging during development This is not meant to be a long-term solution. Remember to remove or disable this hack before deploying to production. For a more robust setup, consider exposing your scheduled tasks through an admin/debug endpoint or using Spring Boot Actuator with proper security controls.  ( 3 min )

    How to Keep TextInput Value in Dart when Dismissing Keyboard
    When building applications with Dart and Flutter, you might come across the frustrating issue of losing data on a TextInput field when the keyboard is dismissed. This typically occurs because the state of the input field is not being managed correctly. By utilizing a TextEditingController, you can ensure that the value users type into the text field remains intact even after they click 'Ok' or use the back button to hide the keyboard. Understanding TextEditingController In Flutter, a TextEditingController is an object that can be used to control a text field. It helps in retrieving the current value of the text field, listening to changes, and manipulating it. If you don’t initialize a TextEditingController, the text field will not maintain its state after interactions. Why the Value Disap…  ( 4 min )
    Mastering Kotlin Coroutines in Android: A Practical Guide
    Modern Android development is all about writing clean, efficient, and asynchronous code — and Kotlin Coroutines have become the go-to tool for that. If you're tired of callback hell and want to write non-blocking, readable code, coroutines are your best friend. In this post, we'll cover: ✅ What are Coroutines? 🔁 Coroutine vs Thread 🧭 Coroutine Scope 🚀 launch vs async 🔄 withContext ⚠️ Exception handling 📱 Real-world Android examples A coroutine is a lightweight thread that can be suspended and resumed. It allows you to perform long-running tasks like network calls or database operations without blocking the main thread. Coroutine = Co + routine i.e. it's the cooperation among routines(functions). Think of it as a function that can pause mid-way and resume later, keeping your UI respo…  ( 5 min )

    Clean Code Is a Habit, Not a Talent
    A smart developer once said: "Clean code isn’t some magic skill — it’s just a habit you build over time." And guess what? You can totally build that habit. Clean code means writing code that's clear, organized, and easy to work with. It makes your life (and your teammates’ lives) way easier. But let’s be honest — how many times have we said, “I’ll clean this up later”? Here’s the truth: There’s never a perfect time to refactor Messy code turns into technical debt — and sooner or later, you’ll have to deal with it. It’s better to start clean than to fix bugs forever later. Writing clean code isn’t as hard as it sounds. Actually, it can feel really natural once you get the hang of it. Think of it like building something with care — not just typing stuff out. Here are a few simple tips to he…  ( 4 min )
    Bora simular uma compra completa com Azure Durable Functions e padrão Saga? 🎉
    Já pensou em orquestrar todo o processo de compra de um marketplace com segurança, mesmo se der algum problema no meio do caminho? Hoje vamos fazer exatamente isso usando Azure Durable Functions em Node.js e o padrão de Saga para garantir que, se algo falhar, a gente consiga desfazer as etapas anteriores sem stress. Vamos passo a passo montar uma simulação de compra completa – do pagamento ao envio – num estilo bem descontraído (vem comigo que eu te explico 😉). Antes de botar a mão no código, vale aquela explicação rápida: Saga é um padrão de arquitetura usado para gerenciar transações distribuídas ou processos de negócio de longa duração. Em vez de travar tudo em uma única transação gigante (o que é impraticável num monte de microsserviços), o Saga divide o processo em uma sequência de e…  ( 16 min )

    Best Practices for Efficient Chemical Procurement
    Chemical procurement plays a critical role in industries like pharmaceuticals agriculture manufacturing and energy. However managing chemical purchasing efficiently requires more than just comparing prices. It demands a careful balance of safety compliance cost savings and strong supplier partnerships. When it comes to chemicals compliance is non-negotiable. Companies must stay updated on regulations like REACH OSHA EPA or local environmental laws. Start by creating an internal compliance checklist that covers everything from product labeling to storage and transportation rules. Work only with suppliers who provide clear documentation including safety data sheets and certifications. Do not treat suppliers as just vendors treat them as partners.

    From Java to Go: Why Composition is Preferred Over Inheritance
    What Drives New Languages Like Rust and Go to Embrace Composition and Abandon Inheritance? Java has a guideline: “Don’t use inheritance unless you have a good reason.” But Java doesn’t strictly limit inheritance — you can still use it freely. Go, however, is different: it only allows composition. So why do modern languages promote composition? Actually, it’s not just new languages — even the veteran Java mentions in Item 16 of Effective Java: “Favor composition over inheritance.” Inheritance is a powerful way to reuse code, but it may not be the best method. So it’s worth thinking this through carefully. Without diving into specific code, let's talk about the concepts. I believe we can explore this topic from the following perspectives: The characteristics of inheritance and composition Wh…  ( 8 min )

    This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Exploring the Possibilities In the middle of a long workday, how many times have you written a Slack message, paused, and thought: “Hmm… that sounds too harsh. Should I rewrite that?” Or: “Can this be clearer? Simpler? More polite?” Now you don’t have to second guess. Parrot is a Slack app that transforms your raw, rushed, or robotic messages into something more human — with improved politeness, clarity, or simplicity. You just type: /polite Can you do this now? And Parrot replies: "Would you be able to do this when you get a chance?" Or: /clarity Let’s sync up sometime soon. And Parrot says: "Let’s schedule a quick meeting this week to align." It’s like Grammarly — but instant, and inside Slack. How …  ( 5 min )
    🧙‍♂️ JavaScript Decorators Explained – Like Magic, but Real!
    Decorators are a powerful way to enhance classes and their members (methods or properties) without touching their original code directly. 🎯 decorate behaviour in a clean and reusable way. Like adding toppings to a pizza 🍕 ⚠️ Decorators are a Stage-3 proposal in JavaScript. You can use them with TypeScript or Babel. A decorator is a special function you can attach to: A class A class method A class property It looks like this: @myDecorator class MyClass {} Or for methods: class MyClass { @log doSomething() {} } Think of a decorator as a function that wraps the original function, property, or class to change its behavior. Here's what happens behind the scenes for method decorators: When the class is defined, decorators are executed. The decorator function receives three arguments: ta…  ( 5 min )
    Kafka Producer Stability Check: Ensuring Message Safety in Apache Kafka
    During a recent incident, our team observed message loss from a Kafka producer during an Amazon MSK rolling patch. What began as a routine upgrade quickly uncovered hidden weaknesses in our producer's configuration.

We'll examine key components of data readiness, assessment methodologies, and best practic…  ( 10 min )
    Building a RAG System with Firebase Functions, OpenAI, and Pinecone
    Few months back, I built the GenQL tool to generate SQL queries from natural text with the ability to provide context of database schema of my database to the AI. Here, I'm sharing the concepts of a basic RAG implementation that made it happen. Retrieval-Augmented Generation (RAG) is a powerful approach that combines large language models (LLMs) with external knowledge sources. In this project, I implemented a RAG system using Python, Firebase Functions, OpenAI for embeddings, and Pinecone as the vector database. The system exposes three main APIs: indexing data, searching, and deleting namespaces. Let’s break down the concepts behind each API. Concept: Before you can search your data with natural language, you need to convert it into a format that a machine can understand and compare. Th…  ( 4 min )

    ☁️ Keep Using AWS as Usual
    Hiya 👋! So, it's Sunday, homeboy, and I usually escape debates and negative thoughts. But today, I was scouring dev.to and stumbled across a post boldly titled "Stop Using AWS." It wasn't the first time I'd seen a call to drop Amazon Web Services for something "simpler", but this one hit a nerve, not because it was provocative, but because it misrepresents why AWS exists and what problems it solves. So, I decided to sit back, relax, and explain why you should absolutely keep using AWS, especially if you're serious about software, scalability, and sustainability. The post opens with a classic anecdote: a developer builds an MVP with all the AWS bells and whistles, Lambda, API Gateway, Cognito, S3, DynamoDB, and no one uses it. The conclusion? AWS was overkill. But let's be honest: blaming …  ( 7 min )

    Foundational Project Structure for .NET Projects
    A well-thought-out project structure is one of the most critical aspects of your project. It sets the foundation for how scalable your application will be in the long run. The higher up you go in the structural hierarchy, the more important it is to get it right from the beginning. Mistakes at the top can lead to bad practices and cost you later on. Lower-level decisions (like file or folder organization within a feature) offer more flexibility—it's less painful. Adjusting or removing a single leaf from a tree doesn't impact the whole tree, but doing the same with the entire branch can affect all its sub-branches and leaves. Similarly, changing the fundamental structure of a real-world system is never easy, it's usually extremely risky and time-consuming, so investing in a solid foundatio…  ( 6 min )

    Building a CLI for Multi-Agent Tree-of-Thought: From Idea to Execution - Part 1
    What if LLMs had opinions and argued in threads? What happens when we give LLMs not just memory and tools, but also autonomy, voices, perspectives, and structure? I built a simple CLI tool, a tiny experiment in multi-agent, tree-of-thought reasoning. The tool lets you simulate a conversation between different AI personas, each contributing their thoughts in a threaded format. This concept of enabling language models to work together to solve complex problems, with each agent assuming a unique role based on its strengths, is a central tenet of multi-agent LLM systems. Such systems are often observed to outperform traditional single-agent models, particularly when dealing with intricate tasks that necessitate diverse expertise and collaborative decision-making.

In this quick post, I'd like to share a little bit about my little workaround when I was building my personal website for the first time. Astro has a static-first architecture and I was going to use it without its on-demand SSR feature. So just for a note, this means I couldn't use Astro session that could've been handy for operating states handled by server. Meanwhile, I also used Vue.js alongside Astro with its integration portability (sorry if it looks like I am doing an experiment here, yes I'm still learning). Everything went well until I encountered something in a Vue component that needs the Astro's context object. Say that you need Astro.url. This URL-object property can only be accessed in Astro's render context object:…  ( 4 min )
    Understanding Python Concurrency: Multithreading VS AsyncIO
    Leapcell: The Best of Serverless Web Hosting In Python programming, multithreading is a commonly used means of concurrent programming, which can effectively improve the execution efficiency of the program, especially when dealing with I/O-intensive tasks. Python makes multithreading programming relatively easy with the help of the threading module. This article will delve into the basic knowledge of the threading module and demonstrate the application of multithreading through examples. Before starting, let's first understand some basic concepts of multithreading programming: Thread: It is the smallest unit for the operating system to perform operation scheduling, usually existing inside a process. Multithreading: It refers to running multiple threads simultaneously in the same program. GI…  ( 12 min )
    Qwen 3 vs. Deepseek R1: Complete comparison
    Introduction The Alibaba recently team has released the Qwen 3 Series, including two standout models: the 235B parameter MoE model (with 22B active parameters) and a lightweight 30B version (3B active). As per official docs, the Qwen3-235B-A22B model take on giants like DeepSeek R1, Grok-3, and Gemini 2.5 Pro—and it is doing it with fewer active parameters, faster inference, and open-source accessibility. On the other hand, on a lighter note the Qwen3-30B-A3B outcompetes the previous QwQ-32B with 10 times of activated parameters, and a small model like Qwen3-4B can rival the performance of Qwen2.5-72B-Instruct. Best part, takes fraction of cost per million input and output token, compared to SOTA models. Impressive, isn’t? Alibaba released Qwen 3, featuring efficient MoE models (235B …  ( 14 min )
    May the Nodes Be with You
    Knowledge graphs are powerful tools to visualize and explore your data, and can help uncover new insights and patterns in how your data is related. They are easy to search and navigate, but getting your data into the graph database in the right format can be challenging. And the resulting graph is only as good as the data--- or as they say, garbage in, garbage out. So it's important to define a good schema, or ontology, that describes the entities and relationships you want to extract from your data. With unstructured text, you can use an LLM to extract entities and relationships, and then generate a Cypher query using the model (guide). This can take a lot of the work out of generating the Cypher queries but it comes with the risk of hallucinations, and the security and privacy concerns o…  ( 7 min )

    Podman: Detailed Overview, Advantages, Disadvantages, and Setup
    Podman is an open-source container engine that enables users to create, manage, and run OCI containers and pods across Linux, macOS, and Windows. Unlike Docker, Podman is daemonless, running containers directly under the user's control, which brings unique benefits in security and flexibility. Daemonless Operation Podman does not require a central background service. Each container runs as a child process of the user, reducing resource overhead and improving security by eliminating a single point of failure. Rootless Containers Podman supports running containers without root privileges. This greatly reduces the risk of privilege escalation and is ideal for multi-user systems or environments with strict security requirements. Docker Compatibility Podman’s command-line interface is largel…  ( 5 min )

    Who Controls Your Files in Linux? Discover the Power of Permissions 🔐
    When working in a multi-user Linux environment, not everything is open to everyone—and that’s for a reason. File permissions are a cornerstone of Linux security, ensuring that only the right people can access or modify critical files. Whether you're a budding sysadmin or a curious developer, understanding how Linux handles file access is crucial to maintaining control and security. Let’s break it down 👇 Linux file permissions determine who can read, write, or execute files and directories. Each file or directory is governed by three levels of access: Owner (User) – The creator of the file. Group – Users who belong to the assigned group. Others – Everyone else. Permissions are represented in two ways: Read (r or 4) – View file contents. Write (w or 2) – Modify file contents. Execute (x or …  ( 4 min )

    Scripting Series – Part 6 of 8
    Here we will dive into part 6 in the shell scripting series. Today we will look at how you can use a for loop to iterate through all files in a directory and the function of file comparison. Shell scripting is essential in production environments for automating repetitive tasks, ensuring consistency, and minimising human error. It enables engineers to streamline deployments, manage system configurations, monitor processes, and orchestrate complex workflows with precision. In a high-availability environment, shell scripts act as reliable, lightweight tools that reduce manual intervention and improve operational efficiency. Create the script using VIM. Write the script in VIM and save the file. Apply the necessary permissions to the script so it can be executed. If we do a ls –ltrh we see that the script has been created. It has a green colour to it – indicating that it is now executable. Execute the script using ./ The output of the script, after it has been executed. Stay tuned, part 7 in the series coming tomorrow!

    Turn any photo into a color palette – made a tool for designers & artists
    Hey everyone! I’m a designer/developer who’s always hunting for the perfect color palette, and I got tired of manually picking colors from images. So, I built a free web tool that lets you upload any image (or use a sample), and it instantly gives you a palette of the most important colors – in HEX, RGB, HSL, etc. You can choose between different extraction methods (Vibrant, Material Design, Median Cut, K-Means) depending on what kind of palette you want. It works right in your browser, and nothing gets uploaded to a server. Try it here: https://colorsfromimage.xyz/ Would love to hear what you think! Is it useful for your workflow? Any features you wish it had? Found any bugs or weird results? I’m open to all feedback, and if you make something cool with it, please share! Thanks for checking it out :) Robert  ( 3 min )
    Building Dcup: An Open-Source RAG Pipeline with a Twist
    Ever wrestled with a RAG pipeline and thought, “Why is this so damn hard?” We’ve been there—tearing our hair out over complexity and slow performance. So, I built Dcup, an open-source, self-hostable RAG-as-a-Service platform that actually works Very good. It’s a tool to hook your app up to user data with zero bullshit. Here’s the rundown: Tech Stack: Next.js, BullMQ for job queues, OpenAI for embeddings, and Qdrant for vector storage. It’s lean, mean, and scales like a dream. Killer Features: AI-driven retrieval and hybrid search that cuts through the noise. Plus, optional re-ranking if you’re a precision freak. Learn more At its core, Dcup is your bridge to smarter data handling. It takes the complexity out of RAG pipelines by automating the heavy lifting. Here’s how it works in plain English: Data Ingestion: Hook up your data sources—think Google Drive, AWS, or wherever your files live—and Dcup keeps it all synced and current. Data Processing: Your raw data gets chopped into bite-sized chunks and turned into embeddings using OpenAI. (More on embeddings later—they’re cool!) Storage & Indexing: Those embeddings land in Qdrant, a lightning-fast vector database that makes searching a breeze. Advanced Retrieval: Need answers fast? Features like re-ranking and hybrid search dig up the most relevant info in seconds. Think of Dcup as your personal AI assistant that organizes, understands, and retrieves your data like a pro. Big files used to choke us. Performance would tank, and we’d be staring at spinning wheels. Then we got smart—batching and parallel processing turned it around. Now, Dcup eats large datasets for breakfast. This isn’t some corporate ad. It’s a project by dev not shitty vibe coding or whatever the kids call it these days. Star the repo if it vibes with you: Dcup on GitHub. Wanna contribute? Hit me up! Let’s make RAG pipelines suck less together.  ( 4 min )

    9 OOP Design Patterns You Must Know
    9 OOP Design Patterns You Must Know A-Creational Patterns Deal with object creation mechanism to decouple the client code from concrete classes. Factory Pattern: Centralizes object creation logic and returns different subclasses based on input Singleton Pattern: Ensures only one instance of a class exists and provides global access to it. Builder Pattern: Constructs complex objects step-by-step, allowing optional configuration. B - Structural Patterns Help compose classes and objects into larger structures. Adapter Pattern: Allows incompatible interfaces to work together by translating one interface into another. Decorator Pattern: Adds new behavior to objects dynamically without altering their original structure. Proxy Pattern: Acts as a placeholder for accessing another object. C - Behavioral Patterns Focus on communication and interaction between objects. Strategy Pattern: Allows selecting an algorithm or behavior from a family of interchangeable strategies at runtime. Observer Pattern: Enables a one-to-many dependency so that when one object changes state, all its dependents are notified. Command Pattern: An object encapsulates all information needed to perform an action or trigger an event. Over to you: Which of these patterns have you used?  ( 3 min )

    🔌 Accessing Localhost from the Internet – Simple Tunneling Tools
    When you're building a web app on your local machine, sometimes you need to share it with someone online — maybe a teammate, client, or even for testing on your mobile device. But localhost only works on your computer. That’s where tunneling tools come in! They create a secure public URL that maps to your local server. Below are three popular options: Website: https://ngrok.com How it works: You run a command like ngrok http 3000 and ngrok gives you a public HTTPS link that forwards traffic to your localhost:3000. Pros: Very fast and reliable Works well with webhooks (e.g., Stripe, GitHub) Dashboard to inspect requests Cons: Free tier has time and region limits Requires an account after initial use GitHub: https://github.com/localtunnel/localtunnel How it works: npm i -g localtunnel Then run lt --port 3000 Pros: Super simple and open source No signup required Cons: Can be slower or less reliable than others Fewer features, no UI Docs: https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/ How it works: cloudflared CLI and connect your app through Cloudflare. Pros: Very secure Great if you're already using Cloudflare DNS Free with more generous limits than ngrok Cons: Slightly more setup steps Best for advanced users or teams 🧠 Final Thoughts Just pick the one that fits your workflow and you're good to go!

It's a great way for us all to practice some coding. Challenge, My solutions You are given a list of words containing alphabetic characters only. Write a script to return the count of words either starting with a vowel or ending with a vowel. So vowels in English are a, e, i, o, u and sometimes y. It seems clear from the second example that even though weekly ends with a vowel, the task assumes that it is just the five letters. This task is a one liner, and simply counts the words that starts with a vowel letter or ends with one. def word_count(words: list[str]) -> int: return sum(1 for word in words if re.search('^[aeiou]', word) or re.search('[aeiou]$', word)) $ ./ch-1.py unicode xml raku perl 2 $ ./ch-1.py the weekly challenge 2 $ ./ch-1.py perl python postgres 0 You are given two arrays of integers. Write a script to return the minimum integer common to both arrays. If none found return -1. For the command line input, I take two strings and separate them on non-digit characters. My solution takes the two lists and converts them to sets and uses the intersection method & to get values that appears in both lists. If there is one or more values found it returns the minimum value. If none is found, it will return -1. def minimum_common(list1: list[int], list2: list[int]) -> int: intersection = set(list1) & set(list2) return min(intersection) if intersection else -1 $ ./ch-2.py "1, 2, 3, 4" "3, 4, 5, 6" 3 $ ./ch-2.py "1, 2, 3" "2, 4" 2 $ ./ch-2.py "1, 2, 3, 4" "5, 6, 7, 8" -1  ( 3 min )

    Building "Production-Grade" APIs in .NET
    Many engineers build and deploy APIs into production. So we have an API running in production — does that mean it’s truly production-grade? More often than not, the answer is no. We write the code, test it locally (usually alone, on one machine, with one user), and proudly tell the business, "Hey, it’s ready!" Maybe there’s even a QA environment where someone from product gives it a quick click-through and confirms, "Looks good to me!" And then... reality checks in. You get a call on the weekend: “Users can’t log in.” Or worse: “A customer placed an order, and it’s gone.” Now you're scrambling, thinking: “I wish I’d added logs there.” “Why didn’t we catch this earlier?” “How are we supposed to debug this in production?” If that scenario feels familiar, this post is for you.

Complex onboarding: Managing access manually per user or embedding authorization logic deep in every tool becomes hard to maintain. With this panel, companies can: ✅ Centralize internal tool access ✅ Restrict access to only the tools users need ✅ Offload role/policy management to Permit.io Key Ideas: Simple Auth: Login is managed via a static credential list…  ( 7 min )

    Basic Class and Object
    Lets start with basic example of banker problem to understand basic class and object Assume you want to create an account in SBI bank. So you fill that form and your account is created. Now you are the person who created that form. Which attribute or field you will create which is necessary to create an account. Lets say:- Name DOB Aadhaar card no. PAN Card no. class BankForm: __init__(userName,userDOB,userAdhaarNo,userPAN): Rohan=BankForm("Rohan","12-09-2025","xxxx8907","KB1234") you will find an error. why? Because the class doesn't know about the form. It mean that you are creating the form, but for whom. If you are thinking for SBI. Let me tell you they doesn't know. so how we are going to tell them. By using 'self'. class BankForm: __init__(self,Name,DOB,AdhaarNo,PAN): 'self' it just a way to tell SBI I have a form for you. Now you have heard some word like Instance, __init__ and object. Instance:- It is just like Rohan want form for himself.So you have to fill BankForm as in Instance. __init__:- Initialisation of object. Like you want to create form and decide field which is needed for the form. Like Name, DOB, AdhaarNo., PANNo.. Object:- simply it is the field.  ( 3 min )

    Finding Hidden Comic Book Deals: A TypeScript Scraping Solution
    🐙 GitHub Comic book collectors face a common challenge: getting the best value for their money. While the cover price is straightforward, the actual value can vary significantly when you consider the number of pages in each volume. A $20 comic might contain 100 pages, while another at the same price point offers 400 pages. To solve this practical problem, we'll develop a TypeScript program that calculates and compares the price per page, helping collectors make data-driven purchasing decisions. The complete source code for this project is available on GitHub. Using this approach, I bought four 400-plus-page comics for $85 total, including shipping costs. The implementation focuses on the Wildberries e-commerce platform, which serves Eastern European markets. The code structure is modular,…  ( 7 min )
    Forget uniqueness. Do marketing first.
    Forget uniqueness. Do marketing first. When I launched my idea — a simple SaaS for status pages — someone commented: “You're building the same thing that already exists. Where’s the uniqueness?” And honestly? That’s exactly why I decided to build it. The market already exists. Paying customers already exist. Can I sell it? Can I make money from it? That’s what really matters. There was a time when you could “build → launch → get traffic.” Now, product-first is a trap. Instead: Before writing a single line of code, I: Built a landing page explaining what the idea is, and who it's for Defined pricing (based on competitors and positioning) Started driving traffic Measured how many leads I could get Learned if I could "sell" the idea, even without a working product That’s the real funnel: find traffic → qualify leads → convert → check economics. Not “does the idea have demand?” I’m testing: Can I attract and convert leads in this market? Can I acquire users profitably? Can I turn this into a sustainable business? That’s the difference between a side project and an actual SaaS business. In a big enough market, there's room for dozens of products. Distribution > innovation Marketing > features If you can build a profitable funnel — traffic, conversions, retention — you win. That’s what I’m focused on.

    A Comprehensive Guide to Object-Oriented Programming (OOP) Concepts Introduction
    Object-Oriented Programming, commonly known as OOP, is a programming approach that organizes code around objects rather than actions. This paradigm has become a cornerstone in modern software development because it helps developers manage complexity, reuse code, and create scalable systems. In this article, we’ll explore the fundamental concepts of OOP—classes, objects, inheritance, encapsulation, abstraction, and polymorphism. By the end, you’ll have a clear understanding of these key principles and how they work together to create robust software. Let’s start with the basics: classes and objects. Think of a class as a blueprint for creating objects. It defines what an object will look like and how it will behave. A class is like a recipe—it tells you what ingredients (attributes) you nee…  ( 6 min )
    Understanding Polymorphism in Python: A Comprehensive Guide
    Introduction Polymorphism is one of the most powerful and flexible features in Object-Oriented Programming (OOP). While inheritance might be the most unique aspect of OOP, polymorphism is arguably its most powerful tool. But what exactly is polymorphism, and how does it work in Python? In this article, we'll break down the concept, explain how it works with examples, and show you how to use it effectively in your own code. The term "polymorphism" comes from the Greek roots "poly," meaning "many," and "morph," meaning "form." In the context of programming, polymorphism refers to the ability of a variable, function, or object to take on multiple forms. Essentially, it allows different classes to be treated as if they are instances of the same class through a common interface. Consider a sc…  ( 5 min )
    When and Where to Use Inheritance in Python
    Introduction Inheritance is one of the most powerful features of Object-Oriented Programming (OOP), allowing developers to create a hierarchical relationship between classes, promote code reuse, and follow the DRY (Don't Repeat Yourself) principle. However, as powerful as inheritance is, it’s not always the right tool for the job. Misusing inheritance can lead to complex, hard-to-maintain code. In this article, we’ll explore when and where you should use inheritance in Python, helping you make informed decisions in your software design. Before diving into when and where to use inheritance, it’s important to understand its primary purposes: Code Reuse: Inheritance allows you to reuse existing code by extending or modifying it in a new class, saving you from writing redundant code. Hierarc…  ( 5 min )
    Understanding Inheritance in Python: A Comprehensive Guide
    Introduction Inheritance is often considered the "holy grail" of Object-Oriented Programming (OOP). While many programming languages offer features like encapsulation and abstraction, inheritance is a powerful feature unique to class-based languages like Python, Java, and Ruby. In this article, we’ll dive deep into what inheritance is, how it works, and when you should use it. By the end, you’ll have a solid understanding of inheritance and how to apply it effectively in your own projects. Inheritance is a feature in OOP that allows one class, known as the "child" class, to inherit attributes and methods from another class, referred to as the "parent" class. This means that the child class can use all the features of the parent class, reducing the need to write redundant code. Inheritanc…  ( 6 min )
    How Major Tech Companies Use Abstraction and When You Should Too

    Understanding Abstraction in Python: Simplifying Complexity
    Introduction Abstraction is one of the core concepts in Object-Oriented Programming (OOP) and software development in general. It’s a powerful tool that allows developers to manage complexity by hiding unnecessary details and exposing only what’s essential. But how does abstraction differ from encapsulation, and why is it so important? In this article, we’ll explore the concept of abstraction, how it works in Python, and why it’s crucial for writing clean, maintainable code. At its core, abstraction is about creating a simple interface for complex behavior. It allows developers to interact with a system or component without needing to understand the intricate details of how it works. By focusing on what is necessary and hiding the rest, abstraction reduces complexity and makes software e…  ( 6 min )
    How Major Tech Companies Use Encapsulation and When You Should Too
    Introduction Encapsulation is a fundamental concept in Object-Oriented Programming (OOP) that helps manage complexity, improve code organization, and make software easier to maintain. But how do the biggest tech companies—like Google, Facebook, and Amazon—use encapsulation in their vast and complex codebases? In this article, we'll explore how these industry giants leverage encapsulation, and we’ll also discuss when and how you should use it in your own projects. Google: Simplifying Complex Systems By hiding the internal workings of a module or service, Google allows its engineers to focus on specific tasks without needing to understand the entire system. This makes it easier to manage large teams where different groups work on different parts of the system. Encapsulation also helps with…  ( 5 min )
    Encapsulation in Python: Understanding the Basics
    Introduction When you first hear about encapsulation in programming, it might sound like it’s related to security—hiding data away to keep it safe. However, in the context of Object-Oriented Programming (OOP), encapsulation is more about organization and managing complexity. In this article, we’ll explore what encapsulation really means in Python, why it’s important, and some common misconceptions about it. Encapsulation is the practice of bundling the data (attributes) and the methods (functions) that operate on the data into a single unit, usually a class. It’s a way to hide the inner workings of a class from the outside world, exposing only what’s necessary. Think of it as creating a "black box" where the internal details are hidden, and users only need to know how to interact with th…  ( 5 min )

    Handling asynchronous validators and mutually dependent fields using Isomorphic-validation library.
    In the previous video Quick introduction to isomorphic-validation javascript library I demonstrated how quickly a user-friendly form can be created with UI effects connected to fields' validity states. This is the second part in which I wanted to touch: working with asynchronous validators; conditional execution of validators; handling password and password confirmation fields. See the playground with the code from the video. In this video I showed how a typical sign-up logic can be implemented such as checking an e-mail for being already occupied before submitting a form to create a new account. Asynchronous validators are handled in the same way as synchronous, you only need to keep in mind that their execution takes time. We are simply playing with timings to create UI effects such as showing loaders/spinners while a request is being processed. It is recommended to execute asynchronous validators conditionally when they are mixed with synchronous. For that, this library provides a feature that implements a simple logic: following validators can not be "valid" without the preceding being "valid", therefore it is not necessary to execute them. For example, it doesn't make sense to make a request to the server to check if an e-mail already registered if it doesn't conform to the E-mail format. Also, you don't have to worry about an async validator retrieving an irrelevant result if the user keeps typing while the request is being processed. The library handles such edge cases for you. Handling fields with validity states depending on each other, such as password and password confirmation, is as easy as handling one field. Also, if you need to implement the logic of one field depending on another it is possible using an auxiliary Validation object.  ( 3 min )

    What Developers Can Learn from Designers
    (And Why It Might Make You a Better Coder Than Learning Another Framework) Let’s be honest — developers and designers haven’t always played nicely. One lives in the world of logic, syntax, and structure. The other deals in color, flow, and feel. Developers chase performance and function; designers obsess over whitespace and emotional resonance. It’s easy to see why the two camps often stay in their lanes. But here’s the secret nobody talks about: the best developers steal from designers all the time. Not pixel-for-pixel, but in mindset. In empathy. In approach. Because writing good code is only part of the job — making something people actually enjoy using? That’s where the magic happens. And designers get that instinctively. So, what exactly can developers learn from designers? A lot more…  ( 5 min )

A few months ago, a good friend of mine told me that she removed her favorite health tracking app. I was surprised—it was simple, well-rated, and full of bells and whistles. But when I asked her why, she told me something that stuck with me: That's when it struck me—we're no longer just creating interfaces. What Is Ethical Design? It means asking: Are we collecting just what we require? Are we explaining clearly or sneaking it in in the small print? Are we empowering the user—or exploiting them? Why Ethical Design Matters More Than Ever Here's why: Trust online is easily broken. The wrong experience can cost a user for life. People are informed. Because of tactics like Cambridge Analytica, citizens care about how their data is being used. Regulations are piling up. GDPR, CCPA, and more are holding products accountable. If your design relies on underhanded tactics, it's only a matter of time before users catch on. 5 Practical Tips for Ethical, People-First Design Prioritize Consent Remove Dark Patterns Design for Control Be Transparent Respect User Attention A Better Digital Future Starts with Design Imagine a world in which: Apps ask first before they track. Notifications respect your time. Each click inspires trust, not regret. That's the world that good design can bring. What You Can Do Today: Examine your current design: Is it manipulative or confusing? Engage real users in feedback loops—not data alone. Stand up within your organization. One voice sparks change. Question for you: What's one app you stopped using because it was exploitative? Leave a comment—let's spread awareness together.  ( 4 min )
    Why 100 lines of code is sometimes better than 2 lines of code
    In the world of programming, there's often a race to write the most "concise" or "clever" code. But sometimes, trying to squeeze logic into as few lines as possible can actually hurt more than help. Let's talk about why writing 100 lines of clean, readable code is often better than a 2-liner magic trick, with real-world examples to back it up. ** ** "If I can do this in 2 lines, why write 100?" But here’s the truth: Short code is not always readable It’s harder to debug It's often less maintainable It usually lacks context, error-handling, and clarity Let’s look at some real-life analogies and coding scenarios to understand this better. Let's give some data: You can code minesweeper with less than 100 lines of code. To code Windows 10, you need over a million. The amount of lines …  ( 4 min )
    10 Unique Elixir Language Features Not Present in JavaScript
    JavaScript is a versatile and widely-used language, especially in web development. However, when it comes to functional programming, concurrency, and fault tolerance, Elixir introduces several advanced features that JavaScript simply doesn’t natively offer. Built on the Erlang VM, Elixir is designed for scalability, maintainability, and high availability — making it a compelling choice for developers seeking robust and elegant solutions. In this article, we’ll explore 10 powerful language features in Elixir that are either missing or poorly supported in JavaScript, along with their advantages and potential workarounds in the JavaScript ecosystem. 1. Pipe Operator (|>) 2. Pattern Matching 3. Immutable Data by Default 4. Function Clauses / Pattern Matching in Function Heads 5. Guards in Func…  ( 11 min )
    Archaeology Meets Artificial Intelligence: A New Era of Exploration
    Artificial Intelligence (AI) is reshaping the way we dig, discover, and decode the past. From satellite imagery analysis to artifact recognition, AI is transforming archaeology into a dynamic, data-driven discipline. This fusion marks the dawn of a new era—one where algorithms are just as crucial as excavation tools. Before diving into AI’s role, it’s essential to understand the limitations that have traditionally held archaeology back. Field excavations are labor-intensive, time-consuming, and expensive. Many sites take years, sometimes decades, to fully unearth and understand. Furthermore, only a fraction of potential archaeological sites have ever been explored—leaving countless treasures buried and untouched. Once artifacts are uncovered, interpreting them requires a deep understanding…  ( 7 min )

    The Elegant Art of Killing 'unsafe-inline' in Your CSP
    If you've ever opened your browser console on your "totally secure" website and witnessed a barrage of Content-Security-Policy warnings, welcome to the club. And if your CSP contains the infamous unsafe-inline directive – we might just share a drink at the next security conference. Just make sure to hide that drink from the actual security experts. Let's be honest: not every website needs to obsess over eliminating unsafe-inline. If you're running a simple blog or a five-page brochure site with zero user data and no admin panels, you probably have bigger fish to fry. The security purists might disagree (they always do), but pragmatism has its place in web development. However, if you're handling sensitive user data, have authentication systems, run an e-commerce platform, or face complianc…  ( 5 min )
    Main difference between struct and class.
    The main difference between structs and classes in Swift lies in the way they store and manage data (value type vs. reference type), as well as additional features that only classes have. Here are the main differences: Data Storage value type(independent copy) Example: var a1 = b1 creates a new copy class Example Value Type (struct): struct Person { var name: String } var person1 = Person(name: "Andry") var person2 = person1 person2.name = "Budi" print(person1.name) // Andry print(person2.name) // Budi Example Reference Type (class): class Person { var name: String init(name: String) { self.name = name } } var person1 = Person(name: "Andry") var person2 = person1 person2.name = "Budi" print(person1.name) // Budi print(person2.name) // Budi 2.Inheritance Example: class Animal { var name: String = "Unknown" } class Dog: Animal { var breed: String = "Bulldog" } 3.Deinitializers class MyClass { deinit { print("Object is being deallocated") } } 4.Mutability (Data Changes) struct Counter { var count = 0 mutating func increment() { count += 1 } } If you're building a Swift/iOS app, most data models can simply use structs. But for UI components and complex logic with inheritance, classes are more appropriate.  ( 3 min )

    Refactoring a Messy Codebase: Lessons I Learned
    One of the most underrated but critical skills for developers is the ability to refactor messy code—not just making it work, but making it better. Recently, I worked on a project where I had to dive into a poorly structured codebase with inconsistent patterns, unnecessary complexity, and minimal documentation. Here's what I learned from that experience and how you can approach your next messy project with more confidence. Before diving into solutions, it's important to identify the problems. In my case, the issues included: Duplicated logic scattered across files Inconsistent naming conventions Long, unreadable functions Lack of separation of concerns (e.g., business logic mixed with UI logic) No clear module or folder structure Zero documentation or inline comments It wasn’t broken, but i…  ( 4 min )

    Turning Tuples Mutable — Beyond list()
    We all know that Python tuples are immutable—once created, you can't change their values directly. But what if you need to change their content? Most tutorials will tell you: t = (1, 2, 3) mutable_version = list(t) Sure, this works. But let's explore other techy and creative ways to work with immutable data by transforming or decomposing tuples—without always falling back to a boring list(). Sometimes, you need both index and value. Dictionaries are mutable and can be a neat transformation: t = ("apple", "banana", "cherry") d = dict(enumerate(t)) d[1] = "blueberry" print(tuple(d.values())) # ('apple', 'blueberry', 'cherry') Useful if you're working with positional elements and need to mutate by index. Another way is to decompose the tuple manually: a, b, c = (10, 20, 30) b = 200 t_new = (a, b, c) print(t_new) # (10, 200, 30) Simple but powerful — and keeps the tuple form intact. You can even use *args if you don’t know the length in advance. collections.namedtuple (Bonus Tip!) Want tuples with names and some flexibility? from collections import namedtuple Point = namedtuple('Point', ['x', 'y']) p = Point(1, 2) p = p._replace(x=10) print(p) # Point(x=10, y=2) You’re still using an immutable structure, but _replace lets you mutate-like-update with elegance. Yes, list() is the go-to way, but you can also: Convert to dict if indexes matter. Unpack and rebuild for control. Use namedtuple and _replace() for readable, structured code. Next time someone says "just convert it to a list", hit them with these smarter tools. 😉  ( 3 min )

After the connection is successful, select Export and click New Export. Click Select Table-Select the table name we want to export, select a folder for the target Excel file, and click Start View the results You can see that the exported workbook name and title row name are the table name and field name of the database, respectively, both in English letters. If there are comments in the database table, the comments can be used as the workbook name and title row name. We can also add a date suffix to the exported table name to distinguish it You can also export in batches to csv files View the results  ( 3 min )
    A Comprehensive Guide to React Rendering Behavior
    What is Rendering in React? Rendering is the process of React asking your components to describe what they want their section of the UI to look like, now, based on the current combination of props and state. Think of React components as chefs in a kitchen, preparing dishes based on specific recipes (props and state). React acts like a waiter, taking orders from customers and bringing them their meals. This process involves three key steps: Triggering a render (taking the guest's order) Rendering the component (preparing the order in the kitchen) Committing to the DOM (serving the order to the table) There are two main reasons why a component would render: Initial render - When your app first starts State updates - When a component's state (or one of its ancestors' state) changes When you…  ( 8 min )

    How to Use AI in Go with LangChainGo (Very Easy!)
    Have you ever wanted to use AI in your Go (Golang) programs? It may sound hard, but with LangChainGo, it’s actually very easy. In this post, I will show you a simple example to get started. LangChainGo is a Go library that helps you use language models (like Google AI, OpenAI, etc.) in your Go programs. You can give it a prompt (a question or a message), and it will give you an answer using AI. We will write a small Go program that asks AI to explain something in simple terms. In this case, we ask: "Explain the concept of quantum entanglement in simple terms" The AI will give us an answer we can print. Here is the full code: package main import ( "context" "fmt" "log" "os" "github.com/tmc/langchaingo/llms" "github.com/tmc/langchaingo/llms/googleai" ) func main() { ctx := context.Background() apiKey := os.Getenv("API_KEY") llm, err := googleai.New(ctx, googleai.WithAPIKey(apiKey)) if err != nil { log.Fatal(err) } prompt := "Explain the concept of quantum entanglement in simple terms" answer, err := llms.GenerateFromSinglePrompt(ctx, llm, prompt) if err != nil { log.Fatal(err) } fmt.Println(answer) } First, it sets up a context. It gets your Google AI API key from the environment (API_KEY). Then it creates a connection to the AI using the LangChainGo library. It sends a prompt to the AI. The AI gives an answer. We print the answer. When I run the code, I get something like: "Quantum entanglement is when two tiny particles are connected in a special way, so if you do something to one, the other changes instantly, no matter how far apart they are." Amazing, right? With just a few lines of code, you can use the power of AI! LangChainGo makes it very easy to use AI in Go. You don’t need to be an expert in machine learning or AI. If you know some Go, you can get started right away. Let me know if you try it out or if you have any questions!  ( 4 min )

    How to NOT do monorepos
    Who actually needs a monorepo? Monorepos exist to solve the problems that arise when you you have deeply coupled and interconnected projects. For example, Vue.js has many libraries that depend on it, like Vue-Router, Pinia, Vue-I18N, Vue-DevTools, Vue Test-Utils, etc. So when tweaking the internals of how Vue works, it's important to know that this new version of Vue won't break any of these other libraries, before doing a new Vue release. Another example is Jest, a unit-testing library. It solves dozens of unique problems around unit testing. And consequently those unique problems have been isolated into their own independent repos solely focused on solving their one problem in a version controlled way, like Snapshot testing for example. These other libraries all live in the same monore…  ( 5 min )

    Implementing Vue Modal Route
    @vmrh/modal-route is a package based on Vue 3 and vue-router, implementing the concept of modal routes. It does not include any Modal UI components—only handling visibility states, state passing, etc. This makes it possible to integrate with any library that provides Modal components. When I say "modal route," I mean a scenario where opening a modal causes the URL to change. You might have heard of or experienced what's called a Twitter-style modal, which is a good example of this. Moreover, when you directly visit that URL, you see the modal's content as a full page instead of a modal. This kind of modal route can be easily implemented in Next.js using Parallel Routes. In Nuxt.js, you can use Nuxt Pages Plus to achieve this. The idea to implement modal routes came from a user experience I…  ( 9 min )

    My Journey into AI: Understanding the Building Blocks of Artificial Intelligence
    After a career break, I started exploring ways to rebrand myself and build on what I already knew as a web developer. While playing around with ideas and using ChatGPT as a guide, the concept of building smart solutions with AI really stood out. I revisited some old AI/ML notes from 2020, did more research, and was amazed at how far the field had evolved.

    How I Got Into Tech: From Hacking WiFi in 2013 to Building My Online Identity
    Back in 2012–2013, I was just a curious kid who loved experimenting with technology. I started exploring ethical hacking using BackTrack, tried phishing with HTML, cracked WiFi passwords, and even had access to a huge Pakistani SIM database (which I never misused). Along with my brother and a friend, we once ethically hacked an Israeli motorbike website and left a warning — just to prove a point. I also ran a blog at sh4hz4ib.blogspot.com where I used to teach others about antivirus tools, basic tech tips, and internet safety. Now, I’m rebuilding myself as a software engineer, diving into PHP, JavaScript, GitHub, and web development — and sharing this new journey online as 5hezy. Stay tuned.  ( 3 min )

    Why Big Tech Is Slowly Ghosting Golang
    🦥 “Go” Away Already: Why Big Tech Is Slowly Ghosting Golang Ah, Go — the language that promised to keep things simple, and boy did it deliver. So simple, in fact, that Big Tech is now collectively yawning, stretching, and slowly walking away without making eye contact. In the 2010s, Go was hailed as the antidote to "enterprisey" bloatware. “No generics!” they cheered. “No magic!” they boasted. “No modern features whatsoever!” And for a brief, beautiful moment, it worked — right until engineers realized they actually wanted to do things. Now, in 2025, the hype is flatter than Go's type system. Let’s explore the eulogy evolution of Go's decline. 🧠 1. Simplicity That Stops the Moment Things Get Complex Its "simplicity" is a paper-thin shield that breaks the moment your project scales beyond…  ( 5 min )
    202/365 | ¥10M Job Challenge - Another day
    I was so exhausted last night that I fell asleep right away. I’m noticing signs of burnout again—it’ll probably take some time to recover. I woke up at 6:00 this morning, and luckily my body felt okay up until noon. Sleeping when you're tired is the most natural thing for a human, but in the high-pressure, long-hours environment of IT, it becomes really difficult. Ironically, burnout often leads to insomnia. There are a lot of necessary chores in life that, once taken care of, can make our daily routine and work much easier. On rare days off, it's not just about resting—we should also take the time to handle those tasks so they don't get in the way of our goals. Another day—let’s keep going!  ( 3 min )

    Building a Bulletproof E2E Testing Strategy for User Authentication
    Building a Bulletproof E2E Testing Strategy for User Authentication Authentication is the gateway to your application, making it critical to test thoroughly. Here's how to build a comprehensive testing strategy for auth flows. Registration typically involves: Form validation Account creation Email verification Initial profile setup The verification step tends to be the trickiest. We've developed a streamlined approach using dedicated testing mailboxes that reliably receive verification emails, making our tests deterministic instead of flaky. Test various scenarios: Successful login Invalid credentials Account lockout Password recovery MFA adds complexity: SMS verification Authenticator apps Email codes Recovery methods This often breaks automation due to email dependencies. Our solution involves pre-provisioned mailboxes that can be programmatically checked for reset links. Isolate email dependencies: Use a separate email testing system rather than production email providers. Create isolated test accounts with predictable states Test security boundaries, not just happy paths Simulate API failures intentionally I've compiled these practices while working on a massive authentication system overhaul. The email verification part was solved with a specialized system — those interested in a similar approach can check my setup (hint: it involves omypost).

    Automation Pitfalls That Slow Down Your Testing Cycle
    5 Automation Pitfalls That Slow Down Your Testing Cycle Test automation should accelerate development, but certain bottlenecks can nullify these gains. After working with dozens of QA teams, I've identified the most common automation pitfalls. Inconsistent environments lead to inconsistent results. Containerization helps, but doesn't solve everything. Perhaps the most notorious bottleneck. Tests that need to validate email verification flows often: Rely on actual inbox access Need to parse verification codes Break when email delivery is delayed Require complex maintenance We solved this by implementing a dedicated testing mailbox system (similar to what I found at omypost.com), allowing us to generate unlimited testing inboxes on demand. Third-party APIs often impose rate limits that throttle your tests. Creating, maintaining, and cleaning test data consumes excessive resources. Running tests sequentially wastes precious time. Of all these pitfalls, email verification testing offered our greatest efficiency gain. By switching to a dedicated email testing service, we: Eliminated manual account creation Automated verification code extraction Ensured reliable email delivery Scaled tests without hitting provider limits What automation bottlenecks have you overcome?

    Formatting Text: Bold, Italic, Underline, and More
    Introduction Text formatting plays a crucial role in emphasizing important information, improving readability, and guiding the reader's attention across your webpage. In HTML, you have various tags specifically designed to format text without relying on CSS initially. In this blog, we’ll explore how to make text bold, italic, underlined, and introduce other formatting tags realistically used in modern web development. Emphasizes Key Points: Important phrases or actions stand out. Enhances Readability: Well-formatted content is easier to scan. Improves Accessibility: Screen readers can identify emphasized text when proper semantic tags are used. Adds Semantic Meaning: Helps search engines understand the significance of content. Tag Purpose Example Use Case Bold text (visual only) Highlight keywords Important text (semantic bold) Emphasizing critical warnings Italic text (visual only) Styling foreign words Emphasized text (semantic italic) Emphasizing an important phrase Underlined text Denoting links or special text Highlighted text Highlight search terms Smaller text size Fine print or disclaimers Deleted text (strikethrough) Show old price in pricing tables Inserted text (underlined) Track changes or edits Subscript text Chemical formulas Superscript text Footnotes, exponents Syntax using : This is a bold word in a sentence. : This is a very important announcement. : He said it was a fait accompli. : You must complete the project on time.

    Working with Headings: h1 to h6 Explained
    Introduction Headings are one of the first building blocks you use when structuring a webpage. They are crucial for organizing content, guiding users, and helping search engines understand your page's hierarchy. But using headings properly isn’t just about making text bigger or bolder — it's about semantic structure, accessibility, and SEO (Search Engine Optimization). In this guide, we’ll explore everything you need to know about HTML headings: from h1 to h6, including best practices, real-world examples, and common mistakes. Definition: Headings in HTML are special tags ( to ) used to define the titles or subtitles of a page section. Each heading level represents a different level of importance, with being the highest and the lowest. Syntax Example: Main Title Subsection Title Smaller Subsection Visual Structure: Break up large blocks of text, making pages easier to scan. Semantic Meaning: Give meaning to the page content hierarchy. Accessibility: Assist screen readers and assistive technologies to navigate content quickly.

    The Future of AI: Are We Hitting the Limits of Scaling Laws?
    In recent years, AI has taken a giant leap forward, especially with large language models (LLMs). The trend has been clear: bigger models, more data, and increased computing power lead to better performance. But are we reaching the end of this scaling journey? In this article, we explore the scaling laws debate and what it means for the future of AI. Scaling laws have driven AI improvements, but limits may be approaching. Larger models require more data and compute, but diminishing returns are a concern. New paradigms in AI, like reasoning models, may redefine scaling. The journey of LLMs began with OpenAI's release of GPT-2 in 2019, which had 1.5 billion parameters. Then came GPT-3, a game-changer with over 100 times the parameters of its predecessor. This marked the start of the sc…  ( 5 min )

    Presale Managers: Increasing Margins and Driving IT Companies Toward Success
    In project management, each stage of the project lifecycle plays an important role. One of the most critical but often underestimated stages, in my opinion, is presale. This is the phase when the company interacts with the client, gathers requirements, proposes solutions, and lays the groundwork for project initiation. Many IT companies try to save costs by relying on regular sales managers during the presale stage or do not recognize the need for a dedicated employee for this role. This approach is not ideal, especially when the project requires precision, detailed planning, and deep technical expertise. Here, we will thoroughly examine what presale is, what a Pre-Sale Manager does, and why it is better for successful project implementation to have a dedicated Pre-Sale Manager rather than…  ( 7 min )
    Is AI really something anyone can use?
    Just a personal reflection on AI and how we relate to it. With alcohol, we say: "Don't drink too much." All of these share an unspoken assumption: But with AI, it’s increasingly being framed as something everyone should adopt— I find that a little strange. To me, the addictive nature of AI—and how deeply it can shape our thinking and personality— People often talk about the "digital divide." For example: Very few people—maybe only a small group of highly self-aware users—can answer that. In fact, I sometimes feel that the more intelligent or capable someone is, So maybe what we really need isn’t “AI for everyone,” It’s a difficult question.

    How to Calculate and Actually Reduce Your Churn Rate
    Most founders don't realize they have a churn problem until it's already slowing them down. You're getting new signups. You're shipping updates. You're seeing some growth. But month after month, MRR barely moves. Sometimes it even drops—quietly. That's the part no one wants to admit: you can be doing everything right on paper, and still lose users fast enough that you never feel the impact of your growth. That's churn, and it's a silent killer. I know this because I've been through it. When I launched UserJot, a customer feedback tool for SaaS teams, I focused hard on new acquisition. But I quickly noticed something strange: people would sign up, leave feedback, then disappear. No complaint. No unsubscribe survey. Just gone. That's when I started paying attention to churn.

    CH-02 : The Time Traveler’s Bug
    Jai leaned back in his chair, a smug grin on his face. “Veeru, my friend, we’ve done it! The world’s first time-traveling app!” Veeru, sipping his chai, raised an eyebrow. “You sure this works? Last time, we ended up in 1975, and Gabbar stole my phone!” Jai rolled his eyes. “Relax. I’ve fixed all the bugs. Look, we just enter a date, and — “ He typed “March 30, 2025, 10:00 AM IST” into the console and pressed enter. Poof! The screen flickered. The app showed March 29, 2025, 11:30 PM. Veeru choked on his chai. “Eh? That’s yesterday! What kind of time travel is this?!” Jai’s confidence crumbled. He scanned the code, mumbling, “Must be a daylight saving issue… Oh no.” His face turned pale. “I used java.util.Date and SimpleDateFormat. The old Java date-time APIs!" Veeru blinked. “So?” Jai sighed. “They don’t handle time zones properly! The app defaulted to UTC, ignoring IST.” Veeru scratched his head. “So, how do we fix it?” Jai cracked his knuckles. “We use java.time! The modern API makes it easy." He replaced: SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); Date date = sdf.parse("2025-03-30 10:00:00"); With: DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"); ZonedDateTime dateTime = LocalDateTime.parse("2025-03-30 10:00:00", formatter) .atZone(ZoneId.of("Asia/Kolkata")); Jai hit run. This time, the app correctly displayed March 30, 2025, 10:00 AM IST. Veeru cheered. “Now that’s time travel!” Jai smirked. “Lesson learned: Never mess with old Java date APIs. java.time is the future!" Veeru chuckled. “Good. Now, let’s set it to 1975 again — I have unfinished business with Gabbar!” 📖 To be continued… 🚀 ✔ java.util.Date & SimpleDateFormat have time zone issues. java.time (LocalDateTime, ZonedDateTime) for correct time handling. ✔ Always specify a **ZoneId **when working with date and time in Java.  ( 3 min )

    Kidnapped dad of crypto businessman freed from ransom attempt: Report
    The father of an unnamed crypto entrepreneur was freed by police in Paris, France, during a law enforcement raid of the property where the man was held captive for ransom over several days. According to reporting from Le Monde, the May 3 raid resulted in five arrests. Local outlet Le Parisien also said the kidnappers demanded between 5 million and 7 million euros, or up to $7.9 million, to release the captive man. Although the details on the identity of the victims remain scant, likely for security reasons, the crypto entrepreneur and his father co-owned a crypto marketing firm based in Malta, French media reports. This incident features similarities to the kidnapping of Ledger co-founder David Balland in France in January 2025. Balland was also held for a crypto ransom until he was freed …

    How to set up stop-loss and take-profit orders
    Key takeaways Bitcoin and crypto traders can rely on automated orders on their trading platform to limit losses and secure gains. Stop-loss orders in Bitcoin trading started as manual risk management in the early 2010s. Now, they have become advanced, automated tools on today’s exchanges. In the algorithm era and bot pestering, proper trading tools like stop-loss and take-profit orders will help you protect your trades. Setting up advanced BTC trading strategies doesn’t guarantee a successful risk management plan. Monitoring the market regularly helps you understand current conditions. This way, you can avoid strategic mistakes. Stop-loss and take-profit orders in trading were used long before Bitcoin. In traditional financial markets, they were already used as a risk management and …
    Is this the end of Bitcoin DeFi?
    Opinion by: Markus Bopp, CEO of TAP Protocol Not long ago, the idea of Bitcoin as a government-backed reserve asset seemed like a stretch. The US Federal Reserve’s move to establish a Strategic Bitcoin Reserve marks a clear turning point. Once dismissed as a speculative asset or niche investment, Bitcoin is increasingly being treated by some governments and financial institutions as a national store of value. This evolution puts blockchain development at a crossroads. On one hand, memecoins, once dismissed as internet jokes, have dominated transaction volumes and social buzz on leading platforms. On the other hand, institutions and governments are taking the world’s most popular cryptocurrency — Bitcoin (BTC) — seriously and investing in infrastructure to secure it for the long term. If B…

    Pro-crypto Democrats pull support for stablecoin bill in last minute
    A group of US Senate Democrats known for supporting the crypto industry have said they would oppose a Republican-led stablecoin bill if it moves forward in its current form. The move threatens to stall legislation that could establish the first US regulatory framework for stablecoins, according to a May 3 report from Politico. Per the report, nine Senate Democrats said in a joint statement that the bill “still has numerous issues that must be addressed.” They warned they would not support a procedural vote to advance the legislation unless changes are made. Among the signatories were Senators Ruben Gallego, Mark Warner, Lisa Blunt Rochester and Andy Kim — all of whom had previously backed the bill when it passed through the Senate Banking Committee in March. The bill, introduced by Senator…

    The AI Skill Overlord: A Self-Mutating Monolith in the Making
    The AI Skill Overlord: A Self-Mutating Monolith in the Making They thought AI skill management had to be rigid. They thought continuous and heuristic skills would forever clash, forcing developers to act as skill arbitrators. But we’re building something better—something adaptive—something that learns and evolves on its own. Welcome to SkillBranch, an experiment in AI self-mutation, where skill execution is no longer a battle, but an evolutionary process. The Blueprint for AI Evolution The days of juggling multiple continuous skills are numbered. Instead of a chaotic swarm, there will be one active continuous skill, absorbing and adapting based on real-time feedback. When a heuristic skill needs to take over? The active skill simply disappears, unaware that something else is handling the request. And if a continuous skill fails—if it proves unworthy—SkillBranch eliminates it, shifting control to a more capable skill. No arbitrary exclusions, no wasted execution cycles, just pure optimization in motion. How This Plan is Taking Shape At the core of this system lies AXLearnability, ensuring that: Success reinforces dominance—if a skill performs well, it remains active. Failure triggers replacement—weak skills are swapped out automatically. Pending heuristic execution erases awareness—continuous skills don’t even realize they were ignored. Instead of managing exclusions or priority levels, SkillBranch’s self-regulating mutation lets AI repair itself, adapting without human intervention. What Comes Next? This is still in development, a framework being forged in experimentation. As the system grows, real-world data will refine its ability to mutate, and soon, continuous skills won’t just be active—they’ll be intelligent, transforming with each interaction. This is AI Darwinism, where survival belongs to the most efficient, the most reliable, and the most adaptive. Once deployed, there is no going back. 🔥  ( 3 min )
    "Quantum Leap: How Startups and Tech Giants are Shaping the Future of Computing"

    How to Avoid JavaScript for Infinite Scrolling Using HTMX
    Infinite scrolling is a popular UI pattern that allows users to scroll through a large set of data without having to click through pages. Traditionally, implementing infinite scrolling involves JavaScript to detect when the user reaches the bottom of the page and then loading more data. With HTMX, you can avoid writing custom JavaScript while achieving the same functionality using server-side rendering. In this tutorial, we’ll walk through how to implement infinite scrolling with HTMX, keeping your app fast and lightweight. Start by creating a simple Flask app that serves the main page and provides an endpoint to load more items as the user scrolls. First, install Flask if you don’t already have it: pip install flask Create a basic Flask app in app.py: from flask import Flask, render_templ…  ( 4 min )

    AI in Software Development – Between Productivity Gains and Knowledge Loss
    Work-related Contact As a Java developer with ten years of professional experience, I rarely need AI support. Here, AI serves more as a sparring partner to validate ideas or make small optimizations. In the frontend domain, however, it’s a different story. My knowledge is much more limited in this area, so I rely heavily on AI, often as a near-complete code generator rather than just for small snippets. This makes me feel productive while actively learning – my willingness to learn is high here. I often ask the AI why something works the way it does. When it comes to PowerShell scripts, my interest completely fades. I’m not even willing to learn this language. Instead, I let the AI generate entire scripts and appreciate that it takes this work off my plate. The complexity is usually mana…  ( 6 min )

    useRef
    Şimdi daha detaylı bir şekilde, bir benzetme ile açıklayalım. useRef Ne İşe Yarar? useRef, komponentin yeniden render edilmesini tetiklemeyen bir "değer tutucu" sağlar.

    Building a Living Game Ecosystem: From Forests to Wildlife to Economy
    Introduction This isn’t just about immersive gameplay, it’s about helping players understand how sustainability works through simulation. Whether used in a survival game, an educational tool, or a training environment, this model encourages critical thinking about natural systems and human impact. Forests as Active Systems If players or AI chop too many trees without replanting, the forest becomes unhealthy — reducing future wood output and halting wildlife spawns. Reforestation is possible, but slow. Trees take in-game weeks to mature, which encourages foresight and planning rather than constant exploitation. Wildlife Populations Tied to Habitat From Ecosystem to Economy Educational Potential Conclusion By linking forest health, wildlife populations, and economic decisions into a single system, this simulation helps players feel the weight of environmental balance. It’s not a warning, it’s a mirror. And it shows that even in a fantasy world, the rules of sustainability still apply. As I continue developing this platform, my goal is to make it not just a game, but a tool — one that blends play, purpose, and ecological insight.  ( 4 min )
    Simulating Emotions and Relationships in AI: A Model for Dynamic Game-Based Social Behavior
    Introduction In my latest simulation project, I’ve developed an emotional AI system where characters experience daily happiness, long-term memories, and evolving relationships. These aren’t scripted cutscenes — they emerge from each character’s traits, interactions, and lived experience. This kind of system isn't just innovative for games — it has far-reaching potential in education, social training, and digital human modelling. By giving AI characters the ability to remember, reflect, and react emotionally, we can begin to simulate the complexity of human Behavior. Every AI character starts each day with a base happiness score. This score adjusts based on events: social encounters, weather, threats, or work satisfaction. But how they interpret those events depends on their personality traits. For example: Memory-Driven Relationships These memories are stored, referenced, and updated — influencing how they speak, act, or even decide where to live. One AI might form a deep friendship. Another may quietly resent a rival. Systems like these could help: Instead of scripting every possible interaction, this approach lets AI learn and grow organically, mimicking how humans form feelings over time. Emotion and memory in AI are not just about realism, they’re about meaning. When virtual characters reflect the psychological nuances of real people, players connect more deeply, and systems become more powerful. This project has shown me how valuable emotion-based AI systems can be, not just in games, but as tools for social modelling, education, and training. I’m continuing to develop and expand this work, with the goal of building intelligent, emotionally aware systems that can inform, challenge, and engage people in entirely new ways.  ( 4 min )

    Teaching Ecology Through Games: How Simulated Forests Can Build Real-World Awareness
    In a world increasingly impacted by climate change and environmental degradation, there’s a growing need to make ecological education engaging, interactive, and deeply felt. One powerful and often overlooked tool for this is: games. As both a developer and systems designer, I’ve spent the past year building a game that does more than just entertain, it teaches players how ecosystems really work. Not through lectures or text, but through consequences. In my simulation, forests are living systems. Trees grow slowly, and each forest has a measurable "health" score that reflects the balance between mature trees, saplings, and destruction. Destroy too much, and the forest deteriorates. Let it recover, and wildlife returns. Players can choose to assign AI foresters to replant trees or exploit the forest and suffer resource collapse. Wild animals, like rabbits and deer, depend on forest health. Their populations rise and fall based on available habitat. Overhunting or deforestation can drive local extinction, and once they’re gone, they’re gone. There’s no magical respawn. Just like in the real world, regrowth takes time, and sustainability requires foresight. The goal isn’t to punish players, it’s to show them what happens when short-term survival clashes with long-term environmental stability. It’s a lesson better felt than taught. What excites me is the potential for systems like these to go beyond games: As classroom tools for science and geography teachers As simulations for environmental education programs As accessible platforms for young players to understand complex systems like reforestation, overhunting, and biodiversity collapse We need more tools that help people internalize ecological cause and effect, not just read about it. Games, especially those with rich simulation mechanics, are a perfect fit. If you're working in education, sustainability, or simulation, I’d love to connect. There’s a lot more potential to explore at the intersection of game design and environmental learning.  ( 3 min )

    Proposal: A Custom Widget Editor for Elementor (HTML/CSS/JS, Built-In)
    🛠️ Proposal: A Custom Widget Editor for Elementor (HTML/CSS/JS, Built-In) Have you ever wanted to build your own widget in Elementor using just HTML, CSS, and JavaScript — without creating a WordPress plugin? Currently, building a custom widget in Elementor requires writing PHP, registering it with WordPress, and deploying it via plugin. For many frontend developers, this creates a barrier. Elementor is a powerful visual builder, but when it comes to adding custom functionality (like animations, dynamic components, or third-party APIs), you're limited to embedding code in HTML widgets — and even then, it's clunky and lacks structure. What if Elementor had a built-in Custom Widget Editor? Code editor tabs for HTML, CSS, and JavaScript Live preview inside the panel Save & reuse custom widgets across projects Export to plugin or Elementor template Syntax highlighting and basic linting Aimed at power users, it would bring the experience of CodePen or JSFiddle directly into the Elementor UI. Here’s a quick visual mockup of how it could look: I’ve shared this idea in the official Elementor GitHub Discussions: 👉 Read or join the conversation here If you're a developer, designer, or part of the Elementor team and this idea resonates with you — I'd love to hear your thoughts.

    Scheduling Transformations in Reactivity
    From pure event graphs to safely mutating state There’s a saying: “Every plan is perfect until you get punched in the face.” In software, that punch often comes the moment your pure logic has to interact with the real world. In our last post, we built a clean, composable model for events — one based on transformations, ownership, and simplicity. But so far, everything has been pure. We transform values, we log them, we react — but we haven’t changed anything. That changes now. Let’s take this innocent-looking example: const [onEvent, emitEvent] = createEvent() onEvent(() => console.log(state())) onEvent(() => setState("world")) onEvent(() => console.log(state())) What should this log? "hello" and then "world"? "world" twice? Or "hello" twice? The answer depends entirely on execution ord…  ( 6 min )

We have great examples for blogs, e-commerce, and dashboards — but nothing geared toward apps like Spotify, YouTube, Bandcamp, etc. A starter template (official or community-built) that helps developers quickly build music or video-based SaaS platforms, including: Modular layout (admin dashboard + public site) SSR-compatible media player YouTube/Spotify API integration Auth system (for creators and users) Stripe billing setup Media upload via Cloudinary, Bunny, or UploadThing Streaming SaaS apps always repeat the same core features — authentication, content dashboards, media playback, etc. Having a purpose-built starter would: Save developers a lot of time Reduce duplicated effort Make Next.js even more attractive for startup and indie devs I’ve shared this idea on GitHub Discussions to get feedback from the community. 👉 Join the discussion here Here’s also a simple wireframe mockup of the concept: If this sounds useful to you, please comment or join the GitHub discussion. I’d love to co-build an MVP if there’s interest. Thanks for reading!  ( 3 min )

    How to use canvas in Web Workers with OffscreenCanvas
    Lately, I have been working on a feature to capture images from media streams and scale them down to reduce their size. This helps save storage and reduce costs before uploading the images to a storage service. For this, I used Canvas to render the image data from the stream and then convert it into a blob of the required MIME type. Canvas rendering, animation, and user interaction occur on the main thread. If the rendering and animation are intensive, they can affect performance. After a few weeks, we received feedback from users that the application felt laggy and slow. So, I decided to move the whole pipeline to a web worker. However, Canvas requires DOM access for rendering and animations, which is not available in web workers. This limitation makes using Canvas in web workers challeng…  ( 7 min )
    Getting Started with Pydantic: Type-Safe Data Models in Python
    Pydantic is a powerful Python library that leverages type hints to provide robust data validation and serialization. It simplifies the process of defining, validating, and parsing data models, making it an essential tool for developers working with APIs, configuration files, or any data-driven application. In this post, we’ll explore Pydantic’s core concepts, walk through its installation, and demonstrate how to create a type-safe User model. Pydantic allows you to define data models using Python’s type annotations. It automatically validates data against these types, ensuring correctness at runtime. Key benefits include: Type Safety: Catch type errors early with minimal boilerplate. Data Validation: Enforce constraints like string lengths, number ranges, or required fields. Automatic Pars…  ( 5 min )

    Empowering LLMs: MCP Manager, a Rust Middleware for API Interaction via Model Context Protocol
    Hey Dev Community! I'm excited to share a new open-source project I've built: MCP Manager. Developed in Rust, this tool acts as a crucial piece of middleware designed to enable Large Language Models (LLMs) to interact with and call external APIs using the Model Context Protocol (MCP). While LLMs are incredibly powerful at understanding and generating text, connecting them reliably and securely to external systems to perform actions is still a significant challenge. Existing methods can be ad-hoc, lack standardization, or require complex custom integrations. The only integrations I was able to found are proprietary or paid. The only real alternative is Claude for Desktop, however it is limited to the Antropic models. MCP Manager provides a standardized way for LLMs (initially supporting Goo…  ( 4 min )

    Desvendando SSR, CSR, SSG e RSC: Entenda de vez essas siglas do React e Next.js

    Transformations in Reactivity
    What happens when we stop treating events like second-class signals? Signals have gone through a quiet renaissance. Once a niche concept, they’ve become the backbone of fine-grained reactivity across modern frameworks — from SolidJS to Svelte 5, Vue’s Composition API, and beyond. With laziness, ownership, batching, and async support, signals are no longer just state — they’re a reactive architecture. Meanwhile, events have stayed… familiar. Push-based systems like RxJS still dominate, with powerful abstractions — and plenty of baggage. They’re expressive, but complex. Powerful, but leaky. This series explores a different direction: What if we evolved events the way signals evolved? What if push and pull reactivity didn’t require different paradigms, just different shapes?

    What is Machine Learning really about ?
    📊 Machine learning is about using data to make smart predictions or decisions. But other fields (like statistics or psychology) also work with data, so how they are different than Machine Learning ❓ And the correct answer is - ✅ their goals are different. To understand it much more clearly let me give an example: 🌻 Imagine you have a garden. You notice some flowers are growing really big, and some are small. Now you're curious - why are some flowers bigger than others? 📈 In Statistics: You count how much 🌊 water, ☀️ sunlight, and 🌱 fertilizer each flower got. “Ah! When I give more water, flowers grow bigger!” You make a rule (a model) to explain what makes the flowers grow. "why" here is: “Because they got more water and sunlight.” So you create a model to explain the relationship — you’re interested in the why. ✅ Goal: Understand the cause behind the outcome. 🧠 In Psychology: Let’s say you're studying how your friend feels. When your friend doesn't sleep, they get cranky 😠. You ask: “Why is my friend cranky today?” And you think: “Maybe it’s because they didn’t sleep well 😴.” So you're trying to find the real reason behind feelings or behavior. “Because they didn’t sleep.” You try to find the real reason behind their feelings or behavior. ✅ Goal: Understand human emotions and behavior — again, the why. 🤖 In Machine Learning: You give the computer LOTS of examples: How much water each flower got 💧. How big it grew 🌼 The computer learns to guess flower size just by looking at water and sunlight — but it doesn’t really know why. It just learns to make good guesses. “Why is this flower big?” It might say: “I don’t know, but I saw something like this before, and it turned out big.” ✅ Goal: Make accurate predictions, even if it doesn’t understand why. So, the goal is the key difference in Machine learning vs Others (like statistics or psychology). ✨ Machine Learning is less about explaining why something happens and more about guessing what will happen next, based on patterns in data.  ( 4 min )
    A Beginner’s Guide to Getting Started with Messages in LangChain
    If you've spent any time developing AI, whether it's a chatbot, a support agent, or a simple Q&A app, you've already come across messages. Even if you didn’t pay them much attention, they were there, quietly doing the heavy lifting behind every interaction. So, why should you care about messages in the first place? They are the foundation of how chat models communicate. Messages carry the what, who, and how of a conversation. Without understanding them, you're essentially flying blind. But once you do, you gain precise control over your model's behavior, clarity in structuring your prompts, and flexibility when building more advanced workflows.

    Annotations in Oracle Database 23ai
    In Oracle Database versions prior to 23ai, the Comment functionality allowed users to add descriptive information for objects such as tables, table columns, materialized views, and views. However, this feature had certain limitations: All comments were stored as a single, lengthy text. There was no option to categorize the comments. Oracle 23ai introduces the Annotation feature, which provides similar functionality to comments but with additional capabilities. Using Annotations, users can add structured and categorized descriptions to objects like tables, views, materialized views, indexes, and columns, based on name-value pairs. Key Features of Annotations: Flexibility: At least one Annotation_name is mandatory for an annotation. Multiple Annotation_name and Annotation_value pairs can b…  ( 4 min )
    AI Agents: how they work and how to build them
    Have you heard about AI Agents? Of course, you heard about them. These are the intelligent agents who will take our jobs in a few years! I don’t want to scare you, but someone on Twitter said that “most jobs will become obsolete” in less than 10 years. McKinsey agrees (they say AI Agents will replace 70% of office work), and Goldman, too. So, I guess our clock is ticking. We don’t have much time. It’s probably better to take a woodworking course or something similar. But I am not that good at woodworking. So, let’s try to understand how AI Agents work and if they are that scary. If you read Twitter or Linkedin, AI Agents look like special agents that can do everything. The demos that they share look amazing. However, these agents don’t feel that special when you use them.

    Zod v4: 17x Slower? (and Why You Should Care) 🚦
    Hey everyone! 👋 I'm Dmitry, the creator of Sury—the fastest schema library out there. If you’re a fan of Zod (and who isn’t?), you’ll want to read this. Today, I want to share some surprising findings about Zod v4’s performance, what it means for you, and how to avoid the pitfalls. Let’s start with a little clickbait: Zod v4 became 17 times slower, and nobody noticed 🙈 This is 100% true, but of course, that’s not the whole story. Let’s dig in. Recently, while prepping for the big Sury v10 release, I decided to rerun my benchmarks with Zod v4. The results? Fascinating. For a non-trivial schema, Zod v4 is now 8x faster than before. But when you create a schema and use it just once (a common pattern in React components), performance drops significantly—down to about 6 ops/ms. You might thi…  ( 5 min )

    What I Learned Hosting WordPress on an NGINX VPS (and Optimizing It for SEO)
    A few months ago, I started building my online gaming Blog and E-commerce site for the Roblox gaming community. But instead of going the easy route with shared hosting or a managed WordPress provider, I wanted full control. So I spun up a bare Ubuntu VPS, installed NGINX, and started learning everything the hard (but rewarding) way. Why WordPress on a VPS? No bloat: I wanted a clean, fast stack — no unnecessary plugins or GUIs. More control: From PHP version to rewrite rules, I wanted to tweak everything myself. Cheaper in the long run: VPS plans are affordable and scale well.

    Bots are a fact of life on the internet. Some are helpful—like search engine crawlers. Others scrape your data, spam your forms, or brute-force your login pages.

    I’m testing Google Ads before building my SaaS — here’s why (and how)
    Most indie hackers make this mistake: They build a product — then try to find customers. I’m trying the opposite. I launched a landing page first, and immediately started testing demand with paid ads — even before writing a single line of code. Building a product takes time. And if nobody wants it... all that effort is wasted. Instead of waiting until launch, I want answers early: Are people searching for this kind of product? Will they click? Will they leave a lead? How much will it cost me to get one? What I did: Built a simple landing page on Framer in one day Set up a €20 test budget on Google Ads Created a form to collect early leads Tracked everything manually — no complex funnel yet I made a mistake 😅 600 useless clicks later, I paused the campaign. Second try: ✅ High-intent keywords Simple ad copy No display, no video, no smart automation The result? Lower traffic — but real, relevant visitors. And a few leads. Even with €10–20, I got signal: People are searching for this I’m getting a few signups And I can start estimating my customer acquisition cost This will help me decide: Is this idea worth building? What pricing makes sense? What channels work best? Next steps (Hint: talk to them — don’t ghost them.)

    Understanding onMouseEnter, onMouseOver, and onMouseMove in React
    Recently, I was building an animated tabs component for my website, something similar to the animated tab switcher found on Vercel’s dashboard (below) I was using Framer Motion’s layout animations to animate a background highlight that follows the active tab. Each tab was a div, and I added onMouseEnter and onMouseLeave event listeners to track which tab was currently highlighted. Simple enough, right? It worked... until I started moving my mouse quickly between the tabs. Sometimes, especially when I moved the mouse at a high speed, none of the tabs appeared to be hovered. The highlight vanished. It was as if my mouse had exited all the elements, even though it was clearly moving over them. That behavior didn’t make sense. So I dug in.

    Stop Letting JavaScript Numbers Fool You – Master Them in Minutes!
    title: "Understanding Numbers in JavaScript: A Complete Guide" description: "From floating-point quirks to BigInt, learn how numbers really work in JavaScript with examples and best practices." JavaScript is a powerful and flexible language, but its handling of numbers can be a bit quirky—especially if you're coming from languages like Python or Java. In this article, we’ll break down how numbers work in JavaScript — from basic arithmetic to edge cases you should know. In JavaScript, all numbers are stored as floating-point values, even if they look like integers. console.log(typeof 10); // "number" console.log(typeof 10.5); // "number" JavaScript uses the IEEE 754 double-precision floating-point format. let a = 5; let b = 2; console.log(a + b); // 7 console.log(a - b); // 3 co…  ( 5 min )
    Hugo: don't miss the best part
    Hugo is a fantastic piece of software, IMHO. It's highly flexible and covers lots of great features, which saves hours of work. If you want to dive into theme development, this could be a great contribution for the community. However, it's easy to miss critical concepts if you don't spend enough time learning how to do it right. Hugo is a framework, so it has its specificity. It's impossible to cover everything here, but, roughly speaking, many templates will inherit from generic structures, so you can prevent unnecessary duplication (e.g., HTML markup) just by defining blocks and using hooks: layouts/ ├── _default/ │ ├── _markup/ │ │ ├── render-image.html <-- render hook │ │ └── render-link.html <-- render hook │ ├── baseof.html │ ├── home.html │ ├── section.html │ …  ( 4 min )

    Stop Using AWS.
    How many times have you seen someone build an MVP with all the cloud bells and whistles, only to watch it go nowhere? The product had Lambda functions. It had API Gateway. It had Cognito. It had S3, CloudFront, DynamoDB, CloudWatch, IAM policies, and more. The architecture diagram looked like a subway map. And yet... nobody used it. The truth is simple: you don't need AWS to build something users love. There is a common trap that builders fall into. You read a few blog posts or see a diagram on Twitter and suddenly you think your tiny project needs the same architecture as Netflix. You don’t. Most early-stage projects die not because they lacked scalability, but because they lacked users. Or because the product was confusing, buggy, or didn’t solve a real problem.

    C# vs Angular: Universal Principles of Dependency Injection
    Introduction Dependency Injection (DI) is a concept so deeply ingrained in everyday programming practices that ignoring it could almost be considered a cardinal sin, on par with neglecting version control. But why has DI become so crucial? DI is one of the key principles enabling the creation of flexible and maintainable applications. The philosophy behind it revolves around freeing code from unnecessary details that tightly couple logical components. Components no longer depend on specific implementations of other parts of the system—they simply declare their needs, and DI provides the required dependencies. The goal here is not just to master a trendy technology but to explore a universal architectural tool whose concepts transcend different ecosystems. Studying DI across multiple lang…  ( 10 min )

    Docker Bind Mounts: Supercharging Your Development Workflow
    When building containerized applications with Docker, one common frustration developers face is the lack of live updates when editing code. For example, you tweak server.js or a front-end file, but the changes don’t reflect in the running app. Why? Because Docker copies your project files into the container when you build the image. Once the container starts, it runs on that static snapshot—isolated from your host file system. Restarting the container every time you make a change? That’s inefficient. Enter: Bind Mounts. Bind mounts allow you to map a file or directory on your host machine to a path inside your running container. This means: Your container reads real-time code from your host. You can make live changes on your local system, and see them reflected instantly inside your contai…  ( 5 min )

    Simple Browser Tracking
    ⚠️ Only the technical part is explained. If you care about legality, you're on your own. At the time of writing, this method works in Firefox and Chrome. Tracking users is a touchy topic.

Agora, sua equipe precisa integrar uma nova forma de pagamento, como PayPal, desenvolvida por outra squad ou vinda de uma biblioteca de terceiros. Essa classe PayPal não implementa a interface Pagamento, e isso quebraria o padrão da sua aplicação. Para resolver esse problema sem modificar a biblioteca externa (o que muitas vezes nem é possível), usamos o padrão Adapter, que atua como um "tradutor" entre as interfaces.

    Cut the Crap: Ship Better-Looking Websites (Fast)
    Alright, let's be real. That UI/UX stuff? It's pretty much the only thing your users actually see and interact with. It's the front door to whatever awesome thing you've built. If you put 20% of your efforts into this, it will give you 80% of the results regarding users. The 80/20 of a product. But if you're a code-first dev like me, staring at a blank design canvas feels… directionless. Like, where do you even start? I've been there. I tried building components and designing from scratch. But no matter how much I tried, the results were mediocre at best. The usual advice? "You'll get good eventually."  I used to watch these long tutorials on YouTube. All they do is teach design fundamentals and make you learn Figma anyway. "Figma? What's that? Why? It's hard enough to manage state, fetc…  ( 9 min )
    Conduit: A UI-less node-based system
    This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Exploring the Possibilities I have built Conduit, a domain-specific language (DSL) for creating node-based workflows. Conduit enables developers to create reusable building blocks with an intuitive syntax that can be mixed and matched to build complex data processing pipelines. It's similar to node-based UI tools like ComfyUI but without the graphical interface, offering a code-first approach that's more flexible and embeddable. One of Conduit's most powerful features is its true cross-language compatibility. Unlike many workflow tools that are tied to specific languages or platforms, Conduit workflows can be compiled to native libraries (.so/.dll) and seamlessly integrated with virtually any programming language t…  ( 9 min )
    Understanding Laravel Accessors to transform data
    When working with Laravel Eloquent models, you often need to modify or compute attribute values before using them in your application. This is where accessors come into play—they allow you to manipulate data seamlessly when retrieving it from the database. In this article, we’ll explore: What accessors are and why they’re useful How to define and use them Practical examples (including checking for subtasks) Best practices and when to avoid them What Are Accessors in Laravel? An accessor is a method in an Eloquent model that lets you modify an attribute’s value when accessing it. Instead of manually formatting or computing values every time, you define the logic once in the model, and Laravel automatically applies it. Why Use Accessors? Consistent Data Formatting Ensure dates, names…  ( 4 min )
    Mastering CRON Expressions - A Developer's Quick Guide
    CRON expressions are powerful tools for scheduling tasks — from backups to emails — across servers, cloud platforms, and CI/CD pipelines. While they may look cryptic at first, once you decode the pattern, you unlock a whole new level of automation. A CRON expression is a string with 5 space-separated fields (sometimes 6 or 7 depending on the system) that define a recurring schedule. ┌──────── minute (0 - 59) │ ┌────── hour (0 - 23) │ │ ┌──── day of month (1 - 31) │ │ │ ┌── month (1 - 12 or JAN-DEC) │ │ │ │ ┌─ day of week (0 - 6 or SUN-SAT) │ │ │ │ │ * * * * * Expression Meaning 0 0 * * * Every day at midnight */5 * * * * Every 5 minutes 0 9 * * 1-5 9 AM on weekdays 30 14 1 * * 2:30 PM on the 1st of each month @daily Shortcut for 0 0 * * * Symbol Meaning * Every value , List (e.g., MON,WED,FRI) - Range (e.g., 1-5) / Step (e.g., */10 → every 10 units) String Equivalent CRON Description @reboot — Run at system startup @yearly 0 0 1 1 * Once a year @monthly 0 0 1 * * Once a month @weekly 0 0 * * 0 Every Sunday @daily 0 0 * * * Every day at midnight @hourly 0 * * * * Every hour Always test your expressions using tools like crontab.guru or Cronhub. This format changes based on the system. For example, the Quartz CRON scheduler has a slightly different format to support extra capabilities, such as seconds and nth recursive patterns, like the 3rd Friday of the month. Similarly AWS Cloudwatch has different one.  ( 4 min )

    Understanding TCP 3-Way Handshake: The Heartbeat of Internet Communication
    🔗 Understanding the TCP 3-Way Handshake: The TCP 3-Way Handshake is a fundamental process that establishes a reliable connection between two devices over a TCP/IP network. It involves three steps: SYN (Synchronize), SYN-ACK (Synchronize-Acknowledge), and ACK (Acknowledge). During the handshake, the client and server exchange initial sequence numbers and confirm the connection establishment. TCP (Transmission Control Protocol) is a foundational internet protocol designed to: reliably (no lost or duplicated packets) ✅ Ensure in-order delivery (packets arrive in the order they were sent) ✅ Provide error-checking (detect and fix corrupted data) Unlike UDP (which just throws data out, hoping it arrives), TCP carefully sets up, manages, and closes connections. Before understanding the han…  ( 5 min )
    🌱 A Beginner's Guide to Functional Programming
    How writing pure functions and avoiding shared state can lead to cleaner, more powerful code In today’s world of software development, clarity and maintainability are more valuable than ever. Functional programming (FP) — once considered an academic curiosity — is now a widely used paradigm in real-world applications. But what exactly is functional programming, and why should you care? Let’s break it down. Functional programming is a way of thinking about software construction that treats computation as the evaluation of pure functions and avoids changing state or using mutable data. Rather than telling the computer how to do something (like in imperative programming), you describe what you want done. This leads to predictable, testable, and often more compact code. A pure function: Alwa…  ( 4 min )

    💰 Cost Optimization with AWS Compute Optimizer:
    💰 Cost Optimization with AWS Compute Optimizer. “You can’t optimize what you don’t measure.” — This quote holds especially true in the cloud. In this blog, I’ll walk you through what Compute Optimizer is, how it works, and how I used it in a real-world project to save money without compromising performance. 🔍 What is AWS Compute Optimizer? EC2 instances ⚙️ How Compute Optimizer Works Go to the AWS Console. 🧪 Real-World Use Case: Cost Cutting with EC2 We had 6 EC2 instances of type t3.large in a production environment. These handled various microservices with relatively low average usage but had burst workloads occasionally. Compute Optimizer Analysis: CPU utilization: <10% average Switch to t3.medium We used this migration strategy: Create AMI backups No increase in latency 🛑 Things to Keep in Mind Is this instance intentionally over-provisioned? (e.g., for redundancy or DR) 📦 What About EBS and Lambda? We had a general-purpose gp2 volume attached to our dev environment with almost no IO requirements. Compute Optimizer suggested sc1 (cold HDD), and we tested it for archive-type workloads. ✅ Result: No functional issues, 60% storage cost saved. Lambda In a different project, our Lambda functions had 1024MB memory allocated by default. Compute Optimizer showed average usage around 200MB. We lowered to 512MB, which also reduced the timeout rate and improved cold-start behavior. 📊 How to Track the Savings Use AWS Cost Explorer to monitor actual savings AWS Trusted Advisor → checks for idle load balancers, unused IPs, etc. 🔚 Final Thoughts 🎯 It's free, data-backed, and supports multiple AWS services. In my experience, implementing even 10–15% of the recommendations led to significant savings — without a single service interruption.  ( 5 min )

    Over the course of several years, I embarked on an ambitious solo journey to create a digital education business. What began as a simple idea evolved through multiple iterations—each one teaching me something about technology, process, and the nature of entrepreneurship itself. This is the story of that journey—from Katacoding to Sigmacasts to Octal Stream—and the insights I gained along the way. The concept began with Katacoding, a platform offering live, one-on-one online coding lessons via video calls. While the model had promise, it lacked scalability. That realization led to Sigmacasts, a curated series of educational videos on math and computer science. The production process taught me how to craft educational narratives and use video to communicate abstract ideas. Eventually, these …  ( 5 min )

    AI vs. Human Language: Why AI Will Never Fully Capture Human Communication?
    Artificial Intelligence (AI) has made incredible strides in understanding and generating human language. From chatbots to virtual assistants, AI-powered tools can mimic human conversation, provide customer support, and even write articles. However, despite these advancements, AI will never fully capture human communication. Why? Because human language is deeply rooted in emotions, cultural contexts, creativity, and nuances that AI struggles to grasp. This Blog explores the key differences between AI-generated language and human communication, highlighting why AI will always fall short of replicating human interaction entirely. The Complexity of Human Language Understand sarcasm and irony. AI Lacks Emotional Intelligence: AI vs. Human Emotions Empathy in conversations. Creativity and Storytelling: A Human-Only Domain AI cannot create original ideas. The Power of Personal Experiences Human Storytelling vs. AI The Role of Cultural and Social Influences Keep up with new trends in language. The Importance of Human Connection AI vs. Human Communication Body language and facial expressions. Unintended discrimination in responses. Lack of inclusivity in AI-generated content. Conclusion: AI has revolutionized language processing, but it cannot replace human communication. Our ability to connect emotionally, create original stories, and adapt language based on context makes human interaction irreplaceable. While AI can enhance communication, it will always need human guidance to ensure meaningful, ethical, and culturally aware interactions.  ( 4 min )

    Stop shipping insecure Dockerfiles: real devs don’t run as root
    From base image blunders to run-time disasters let’s lock down that container before it escapes the lab. Introduction: Your Dockerfile is a ticking time bomb unless you secure it Dockerfiles are like spells simple to write, powerful in execution, and incredibly easy to screw up. You write 10 lines, ship it to production, and boom, you’re running a containerized service in the cloud. Feels magical, right? Well, that magic comes with a curse: insecurity by default. Here’s the thing Docker doesn’t stop you from doing dumb stuff. It happily lets you: Run everything as root Add shady scripts from the internet Bake secrets into the image And pull a 2GB Ubuntu base image just to run curl. If you’re guilty of any of these, don’t worry we’ve all been there. But it’s 2025, and the internet is way le…  ( 9 min )

    Apple vs Epic Games: Fight for developers freedom
    How it all starts. Back in August 2020, Epic Games added its own way to pay inside Fortnite, skipping Apple’s built-in payment system. This broke Apple’s App Store rules, so Apple removed Fortnite from the store. In response, Epic sued Apple, saying the company had too much monopoly and was stopping fair competition. The courtroom drama went over several years: September 2021: A judge ruled that Apple was mostly right, but one of its rules—stopping developers from telling users about other payment options—was unfair under California law. Apple had to let developers share links to other ways to pay. April 2025: The court said Apple broke that rule again. Even after the 2021 order, Apple still charged a 27% fee on outside payments and made it hard for developers to show other payment opt…  ( 4 min )

    Inside the Minds of AI Agents: How Their Evolving Behavior Reshapes Business Risk
    In today’s fast-moving digital landscape, Artificial Intelligence (AI) agents are no longer just tools—they’re decision-makers, collaborators, and even strategists. But as these systems grow more autonomous and complex, a pressing question arises: Do we truly understand how AI thinks, learns, and evolves? The evolving behavior of AI agents isn’t just a technical curiosity—it’s a critical business risk that leaders must monitor closely. In this article, we’ll dive deep into the inner workings of AI agents, explore how their behavior can shift over time, and what that means for businesses across industries. What Are AI Agents, Really? Unlike traditional software, AI agents learn and adapt. This ability, while powerful, can lead to unpredictable behaviors, especially as agents interact with new data or collaborate with other agents in a shared system. The Evolution of AI Behavior: A Double-Edged Sword Examples of Evolving AI Behavior: Bias amplification: Over time, AI models may reinforce and amplify hidden biases in training data. Unexpected strategy development: AI agents in competitive environments (e.g., simulations, financial markets) may develop unanticipated strategies that break norms or ethical boundaries. These evolving behaviors can introduce operational, ethical, and reputational risks if not properly understood and controlled. Why Business Leaders Should Care Autonomy Can Create Blind Spots Unpredictability Increases Risk Exposure Regulations Are Coming Strategies to Manage AI Behavioral Risk ✅ AI Explainability ✅ Continuous Monitoring ✅ Ethical AI Governance ✅ Simulation & Testing The Future: Human-AI Collaboration with Guardrails The question is no longer “What can AI do?” but “What is my AI actually doing—and why?” Conclusion 🔍 Stay informed, stay prepared. The more we understand AI behavior, the safer—and smarter—our future becomes.  ( 5 min )

    🚀 Complete Guide to Consuming APIs in Spring Boot
    With RestTemplate, WebClient, and FeignClient (Headers, Clean Code, CRUD) In modern microservice or distributed system architecture, it's crucial to know how to consume REST APIs effectively. In this guide, we’ll explore three powerful ways to consume APIs in Spring Boot: 🔗 RestTemplate – classic and synchronous. ⚡ WebClient – reactive and non-blocking. 🤝 FeignClient – declarative and elegant. We’ll build a common User model and implement full CRUD operations with all HTTP headers (e.g., Authorization, Content-Type, Accept). public class User { private Long id; private String name; private String email; // Constructors, Getters, Setters } ✅ Use when you're building traditional apps with blocking I/O. @Service public class UserRestTemplateService { private final…  ( 5 min )

    Advanced React Hooks Explained With Real World Code Examples: Part 1
    Since the release of React 16.8 in 2019, building a reusable piece of UI (components) has become super easy. Thanks to the introduction of React Hooks. Now we don't write verbose class-based components anymore. Over the years, the React team has introduced a ton of built-in hooks that solve specific problems. But most of the people only stick with just useState() and useEffect(). But there are a lot of hooks that can improve your understanding and ability to write efficient code. As an experienced developer of React, I have tried to explain each of the advanced & newly introduced hooks with proper real-world code examples. Let's build the best app together. Whenever you submit a form in React, you constantly juggle from to write the load of useStates and useEffects with fetch. useActionSt…  ( 8 min )

    The difference between `@RestController` and `@Controller`
    The difference between @RestController and @Controller in Spring Framework lies mainly in how they handle HTTP responses. @Controller Used for: Traditional MVC (Model-View-Controller) web applications. Returns: Usually returns a View (like JSP, Thymeleaf, etc.). ResponseBody: If you want to return JSON/XML instead of a view, you must use @ResponseBody on the method. Example: @Controller public class MyController { @GetMapping("/hello") public String hello(Model model) { model.addAttribute("message", "Hello, World!"); return "hello"; // returns a view named "hello" } @GetMapping("/api") @ResponseBody public String api() { return "This is JSON or plain text"; } } @RestController Used for: RESTful web services (APIs). Returns: Automatically returns JSON or XML responses. Behavior: It is a convenience annotation that combines @Controller and @ResponseBody. So every method returns the body directly, not a view. Example: @RestController public class MyRestController { @GetMapping("/hello") public String hello() { return "Hello, REST!"; // returns as JSON or plain text } } Feature @Controller @RestController Returns View? Yes (by default) No JSON/XML by default? No (@ResponseBody needed) Yes Use case Web UI applications REST APIs Combines with @ResponseBody Already includes @ResponseBody  ( 3 min )

    Live Streaming: Real-time translated subtile with AWS
    Scenario A streaming platform wants to stream sport matches commented in English (of course completely legal) for Vietnamese viewers. They demand that the subtitle needed to be translated to Vietnamese with the lowest latency as possible. This blog is a PoC (Proof of Concept) for the translated streaming subtitle, using AWS Transcribe to transcribe the voice to text, Nova Micro to fix the text and Claude 3.5 Sonnet v2 in Bedrock to translate, with the support of serverless AWS ECS Fargate and Lambda. Why not using Amazon Translate but use Claude 3.5 Sonnet v2 in Bedrock? It is because the streaming videos are in special contexts, using sports vocabulary such as player names, item names which makes AWS Translate cannot identify and translate correctly.

    12.5 Reflection: parameter names
    Nova funcionalidade: Agora é possível recuperar os nomes dos parâmetros de métodos e construtores usando reflection. Como fazer: Use o método getConstructor(...) para obter o construtor desejado. Em seguida, chame getParameters() para obter um array de Parameter. Use getName() para acessar o nome de cada parâmetro. Importante! Por padrão, os nomes exibidos serão genéricos (arg0, arg1). Para ver os nomes reais, é necessário compilar o código com a flag: -parameters Exemplo com flag: javac -parameters Usuario.java Sem essa flag: Antes do Java 8: Dependia de bibliotecas externas, como o Paranamer: Paranamer paranamer = new CachingParanamer(); String[] parameterNames = paranamer.lookupParameterNames(constructor); Vantagens da nova abordagem: Evita dependências externas. Facilita o uso de reflection de forma mais limpa e segura. 🛠️ Como compilar com a flag -parameters: javac -parameters Usuario.java ReflectionTeste.java E depois execute: java ReflectionTeste 🧾 Saída esperada (com -parameters): true: nome true: pontos 🔁 Saída sem a flag -parameters: false: arg0 false: arg1 💡 Importante: Para que os nomes reais dos parâmetros apareçam (nome, pontos), compile com a flag -parameters.

    This Week in Cloud: Unexpected AWS Tour
    Not every week is about shipping cool projects, sometimes it’s just about testing. I spent the week running through various LocalStack Pro sample apps to make sure everything worked as expected. What I didn’t expect was to get hands-on with a whole bunch of AWS services I’ve barely touched before (and a few I had honestly never even heard of). SageMaker → Machine learning workflows RDS → Managed relational databases Neptune → Graph databases Step Functions → Orchestration workflows Glue → Data catalog and ETL MQ → Managed message brokers Route 53 → DNS and traffic routing ...plus the usual mix of storage, compute, and API Gateway goodness. What stood out this week was how much you can learn just by doing. I didn’t plan to dive into graph databases or message brokers, but while debugging and tinkering, I picked up quite a bit. Having everything local with LocalStack definitely made that exploration easier and less intimidating. First things first: I need to finish my Meme App (priorities are priorities). Once that’s wrapped, I’d like to turn some of this accidental learning into small demos and share tips on how to explore unfamiliar AWS services without the usual stress. If you’ve ever gone down the AWS rabbit hole and come out the other side with new scars and skills, I’d love to hear your story too. Just hit me up on Twitter or LinkedIn.

    React - Simple Component with Pagination
    A code snippet for a React component with a simple pagination. When user clicks prev/next button, update query string (page, pageSize) via navigate() - this URL update does not reload the page. At first load and when useEffect([location.search]) sees location.search (query string) changed, populateMyList() runs. When populateMyList() fetches data, setMyList() and setLoading() are called. Those setState calls trigger a render to reflect the new data. import React, { useState, useEffect } from 'react'; import { useLocation, useNavigate } from 'react-router-dom'; export function MyList() { //this stores and tracks our data const [myList, setMyList] = useState({ totalCount: 0, data: [] }); const [loading, setLoading] = useState(true); //we need this to get and manip…  ( 3 min )

    How MCP Leverages OAuth 2.1 and RFC 9728 for Authorization
    Authorization isn’t just a checkbox in agentic systems. It’s a make-or-break layer for security, scalability, and trust. Without a clear way to authenticate dynamically, AI agents either hit brittle, hardcoded APIs or introduce serious security gaps. That’s why authorization has been one of the biggest missing pieces in the Model Context Protocol (MCP). When MCP was first introduced, it focused on helping AI agents interact with APIs. But it left out that one critical capability: authorization. For the past six months, the MCP team has been working to change that, building a secure, dynamic authorization layer that can keep up with the unpredictable nature of agentic systems. The new MCP authorization model is based on OAuth 2.1, as expected. But it also adds an important enhancement: supp…  ( 6 min )
    Maybe Your Business Doesn't Need an App.
    Maybe Your Business Doesn't Need an App. Often, when I'm on discovery calls with potential clients, a common question arises: "Do you think building an app for my business is a good idea?" My response can sometimes be neutral—or even disappointing—but there's an essential reason for that honesty. Statistically speaking, about 90% of SaaS (Software as a Service) startups fail. This fact isn't meant to discourage entrepreneurs but to inject a necessary dose of realism. As a software developer, I notice that of all the apps installed on my phone or computer, roughly 90% rarely get opened after the initial installation. Sure, some might be used weekly, like social media apps or games, but only a few become daily essentials. Think about your usage: development tools (Xcode, VS Code), browsers (…  ( 5 min )

    Real-World Blue-Green Deployment: 10 Lessons I Wish I Knew Earlier
    I started experimenting with blue-green deployment months ago—published a couple of slide decks (one, two), read the docs, thought I had it mostly figured out. Spoiler: I didn’t. Now, after rolling it out in real-world systems (and dealing with the chaos that followed), here are the 10 most valuable lessons I’ve learned—what worked, what broke, and how we made it through. Even with Terraform and Ansible, subtle differences sneak in—especially after a few hotfixes. We had OpenSSL versions drift apart, and legacy clients couldn’t connect after a switch. Version control your infra and regularly diff live configs. Schema changes are where blue-green deployments get risky fast. One rollout crashed due to a new JSONB column in green that blue’s ORM couldn’t handle. Solution? Versioned migrations…  ( 4 min )

    Warren Buffett to step down as Berkshire Hathaway CEO by year's end
    Warren Buffett, the CEO of publicly traded investment company Berkshire Hathaway, announced at the company's annual shareholder meeting that he will step down by the end of 2025, and his chosen successor will take over as CEO, pending approval from Berkshire's board of directors. According to CNBC, Buffett reiterated that Greg Abel, the company's vice chairman of non-insurance operations, who was previously named by Buffett as his successor, will take over. The Berkshire founder announced: "The time has arrived when Greg should become the Chief executive officer of the company at year-end, and I want to spring that on the directors effectively and give that as my recommendation." Buffett added that he would stay at the company in an advisory role "but the final word would be what Greg deci…
    Bitcoin miners should pay costs in depreciating currency — Ledn exec
    Bitcoin (BTC) mining firms should hold their mined Bitcoin and use it as collateral for fiat-denominated loans to pay operating expenses instead of selling BTC and losing the upside of an asset that miners expect to surge in price, according to John Glover, chief investment officer at Bitcoin lending firm Ledn. In an interview with Cointelegraph, Glover said that holding onto the BTC carries several benefits including, price appreciation, tax deferment, and the potential to make extra revenue by lending out BTC held in corporate treasuries. The executive added: "If you are mining, you are generating all this Bitcoin. You understand the thesis behind Bitcoin and why it is likely going to continue to appreciate in the future. You do not want to sell any of your Bitcoin." This debt-based appr…
    Ethereum nears key Bitcoin price level that last time sparked 450% gains
    Ethereum’s Ether (ETH) token is approaching a critical price zone against Bitcoin (BTC), which historically marked the beginning of a massive rebound. ETH price fractal from 2019 hints at bottom The ETH/BTC pair, currently trading near 0.019 BTC, is edging closer to 0.016 BTC — the exact level it reached in September 2019 before rallying nearly 450% over the following year. ETH/BTC weekly performance chart. Source: TradingView The current ETH/BTC setup resembles 2019, with both periods marked by oversold relative strength index (RSI), long stretches below key moving averages, and multiyear declines. In 2019, ETH/BTC fell over 90% in the prior two years, driven by the ICO collapse. As of 2025, the pair is down over 80% from its 2021 peak, weighed by skepticism over Ethereum’s switch to pr…
    Why tokenized gold beats other paper alternatives — Gold DAO
    Tokenized gold carries several benefits over other forms of paper gold, including gold exchange-traded funds (ETFs), according to Melissa Song and Dustin Becker, representatives of Gold DAO, a decentralized autonomous organization that facilitates investor access to tokenized gold. In an interview with Cointelegraph, the DAO representatives outlined three major benefits unique to tokenized gold, including 1:1 redeemability for a specific quantity of physical, serialized gold, usage as collateral in decentralized finance (DeFi) applications, and transactional efficiency through on-demand liquidity. "When you buy an ETF, you are betting on the gold price going up, but you do not own any specific gold bar," Song told Cointelegraph. The pair added that the price of gold surged in 2025 due to t…
    Bitcoin mining — Institutions boost investments amid favorable US climate
    Opinion by: Fakhul Miah, managing director of GoMining Institutional The Bitcoin (BTC) mining industry has never been more attractive to institutional investors. Fintech giants are investing in Bitcoin mining rather than just accumulating the asset, all thanks to the favorable regulatory environment in the US and the profitability margin of BTC.  Then, numerous companies are diversifying by allocating computing power to AI, further strengthening their economics and, thus, investment attractiveness. For now, it looks like the future of the foundational layer for the Bitcoin network could mark the new gusher age. Is Bitcoin mining profitable? Bitcoin mining is still profitable. CoinShares, a digital asset investment firm, shared that the average cost to mine 1 BTC for US-listed miners reache…
    After Zora airdrop goes awry, what’s next for Web3 creator economy?
    Onchain social network Zora has built a reputation as a popular tool for artists, musicians and other creatives to monetize their content onchain, but the recent launch of its eponymous ZORA token has left many users confused and dissatisfied. The token’s price tanked shortly after launch, with users and observers complaining about everything from poor communication from the team to the token’s distribution and utility models.  This comes amid an overall decline in interest in the onchain creator economy and a changing perspective on whether blockchain tools like non-fungible tokens (NFTs) are still useful for creatives who want to monetize their work on the blockchain. With creators and builders shifting focus and NFTs no longer selling like they used to, does the ZORA token drop symboliz…
    What is a sealed-bid token launch?
    What are the various methods for launching crypto tokens? Launching a new token is a critical step for any blockchain project. Token launches enable projects to offer their native assets to early users, investors or supporters while securing capital or encouraging community growth.  From initial coin offerings (ICOs) to fair launches and airdrops, each approach carries different levels of transparency, accessibility and risk. Since projects differ in their goals and target communities, several token launch models have evolved over time.  Some focus on decentralization and wide community offering, while others aim for optimized fundraising or targeted allocation. Elements such as market swings, bot interference and regulatory pressures influence how…
    Deribit eyes US expansion under crypto-friendly Trump admin: FT
    Deribit, the world’s largest crypto options exchange, is weighing an entry into the US market, encouraged by what it sees as a friendlier regulatory climate under President Donald Trump’s administration, according to a recent Financial Times report. The Dubai-based exchange, which processed $1.3 trillion in notional volume last year, is “actively reassessing potential opportunities” in the United States, CEO Luuk Strijers told the FT. He cited the “recent shift toward a more favorable regulatory stance on crypto in the US” as a key motivator behind the decision. Deribit’s potential plan to expand into the US comes amid reports that Coinbase is in advanced negotiations to acquire the platform. In a March 21 report, Bloomberg said both companies have notified regulators in Dubai, where Derib…
    Over 70 crypto firms join forces to tackle big tech’s AI monopoly
    In a move that hopes to challenge Big Tech’s grip on artificial intelligence, AI agent protocol Thinkagents.ai has launched a new open-source framework for building onchain agents that operate autonomously across decentralized networks. While traditional systems aim to restrict data ownership and platform abilities for their users, Thinkagents.ai is creating an interoperable ecosystem owned and controlled by its users. For Mike Anderson, core contributor at THINK, the Think Agent Standard is the future of AI. Anderson and his team developed the Think Agent Standard to enable millions of autonomous onchain AI agents to transact and communicate. The protocol now has over 70 companies, like Arbitrum and Yuga Labs, on board to help out.  The platform is now live, allowing developers, enterpris…
    Arizona governor vetoes bill to make Bitcoin part of state reserves
    Arizona Governor Katie Hobbs has vetoed a bill that would have allowed the state to hold Bitcoin as part of its official reserves, effectively ending efforts to make Arizona the first US state to adopt such a policy. The Digital Assets Strategic Reserve bill, which would have permitted Arizona to invest seized funds into Bitcoin (BTC) and create a reserve managed by state officials, was formally struck down on Friday, according to an update on the Arizona State Legislature’s website. “Today, I vetoed Senate Bill 1025. The Arizona State Retirement System is one of the strongest in the nation because it makes sound and informed investments,” Hobbs wrote in a statement aimed at Warren Petersen, the President of the Arizona Senate. “Arizonans’ retirement funds are not the place for the state t…
    Vitalik wants to make Ethereum ‘as simple as Bitcoin’ in 5 years
    Ethereum co-founder Vitalik Buterin called for simplifying Ethereum’s base protocol, aiming to make the network more efficient, secure and accessible, drawing inspiration from Bitcoin’s minimalist design. In a blog post titled “Simplifying the L1,” published on May 3, Buterin laid out a vision to restructure Ethereum’s architecture across consensus, execution and shared components. “This post will describe how Ethereum 5 years from now can become close to as simple as Bitcoin,” Buterin wrote, arguing that simplicity is key to Ethereum’s resilience and long-term scalability. While recent upgrades like proof-of-stake (PoS) and Zero-Knowledge Succinct Non-Interactive Argument of Knowledge (zk-SNARK) integration have made Ethereum more robust, he said that technical complexity has led to bloat…
    Apple softens crypto app rules, 'hugely bullish' for crypto industry
    Crypto app developers are now free to direct users to payments outside of Apple’s ecosystem without restrictions or hefty fees, after a United States district judge ruled that Apple violated an injunction in its antitrust legal battle against Epic Games. “The Court finds Apple in willful violation of this Court’s 2021 Injunction, which was issued to restrain and prohibit Apple’s anticompetitive conduct and anticompetitive pricing. Apple’s continued attempts to interfere with competition will not be tolerated,” US district judge Yvonne Gonzalez Rogers said in an April 30 court filing. Apple must make changes “effective immediately” “Effective immediately, Apple will no longer impede developers’ ability to communicate with users, nor will they levy or impose a new commission on off-app purch…
    Bitcoin bros at 'the club' may stop US gov’t from buying BTC — Arthur Hayes
    BitMEX co-founder Arthur Hayes says the United States is unlikely to add more Bitcoin to its reserves beyond what it has already seized due to the country’s high debt levels and the stereotype behind “Bitcoin bros.” “I’m not really into the whole Strategic Reserve situation,” Hayes said in a May 1 interview. Hayes doubts any government announcing print money plans for Bitcoin  “The United States is a deficit country; the only way they can do a Strategic Reserve is not sell the Bitcoin they took from people, fine, that’s 200,000 Bitcoin,” he said. Arthur Hayes spoke to Kyle Chasse on his crypto interview series. Source: Kyle Chasse However, Hayes said it’s hard to imagine any “properly elected” politician openly announcing that the government plans to print money to buy Bitcoin (BTC). “Espe…

    Cross-Platform Software Development – Part 1: Yes, Bytes Can Be 9 Bits
    When we say cross-platform, we often underestimate just how diverse platforms really are. Did you know the last commercial computer using 9-bit bytes was shut down only 30 years ago? That was the PDP-10—still running when C was dominant, C++ was just emerging (but not yet standardized), Java hadn’t launched (just one year before its release), and Python was still in development (two years before version 1.0). That kind of diversity hasn’t gone away—it’s just shifted. Today: There are 35+ active CPU architecture families: x86/64, Arm, MIPS, RISC-V, Xtensa, TriCore, SPARC, PIC, AVR, and many more Some use unusual instruction widths (e.g., 13-bit for Padauk’s $0.03 MCU) Not all CPUs support floating-point—or even 8-bit operations And beyond the hardware: 15+ actively used IDEs 10+ build…  ( 5 min )

    My top 5 VScode extensions
    Hi there, I wanted to make this post to recommend some tools that helped me personally as a React Developer over the past 3 years. LinkedIn This article will only cover VS code extensions that helped me during development. Some of these tools were introduced to me by a friend of mine. You can search for them in the VS extension marketplace 👍 It integrates Draw.io into your VScode. Making creating diagrams a lot easier. This tool is useful for creating a mockup design for the frontend of the web application. This is probably one of my favorite Git VScode extensions. A really great tool for visualizing your Git repository commits. I use it to track the commits I made. If you are working with another developer, you can see the commits made by each other in different color trees. This is a tool that has helped me categorise my projects. I have made a lot of projects and they tend to be scattered. This tool helped me organise them into blocks. Clicking on them takes me to the project workspace immediately. One of my favorite tools in my VScode workspace. This extension allows you to store you previous terminal session. You can create a configuration, these configuration can store a set of terminal commands. This is great for variety of functions, like Dockerization, Database migration, and API testings. This is probably my favorite tool out of all the extensions. It prevents the need to add a console.log in my JS files. I can see the output clearly in the console. It boosts my productivity a lot , and I recommend it the most. I hope this article helped with your workspace productivity. Happy coding ! 😄  ( 3 min )

    JavaScript is Not That Hard
    Let’s be honest—JavaScript has been misunderstood for too long. Too many people assume it’s complicated, messy, or only for “real” programmers. But that’s far from the truth. The reality is: JavaScript is not that hard. In fact, once you understand its core principles, it’s one of the most intuitive, flexible, and powerful languages you can learn. It powers nearly everything you see on the modern web. And with the right guide, learning JavaScript can not only be simple—it can be fun. That’s exactly why I wrote the ebook JavaScript is Not That Hard—to prove that anyone can learn JavaScript, even if they’ve never written a single line of code before. Let’s break this down: The Syntax is Human-Friendly if, else, and function—and they just make sense. You Can See Results Instantly It’s For…  ( 4 min )
    [Parte 3] Enviando dados entre aplicações com Module
    Na parte 1 desta série, vimos como o Module Federation permite compartilhar componentes entre diferentes aplicações sem precisar instalar pacotes ou duplicar código. Agora, vamos dar um passo além: como enviar dados de uma aplicação para outra. Imagine que você tem dois apps: 🔵 MF Consumer  — quem consome um componente remoto 🟢 MF Provider  — quem disponibiliza esse componente conforme a imagem abaixo: Vamos supor que o MF Provider tenha um componente chamado App que precisa exibir os dados de um usuário ( nome e email ). Esses dados vêm diretamente do MF Consumer. No MF Consumer, tem o seguinte: MF Consumer Aqui, criei um objeto user e passei como props para o componente Provider , que está vindo do MF Provider. No lado do MF Provider , defini o tipo das props ( ProviderProps ) e usei os dados recebidos normalmente, como faríamos em qualquer componente React, como segue: MF Provider Não é magia. É só React com Module Federation! Ao consumir um componente remoto, você ainda pode passar props normalmente, como se ele fosse local. Isso funciona porque, por baixo dos panos, o Webpack cuida de toda a importação remota — mas o React continua funcionando do jeito que a gente conhece. Com isso, conseguimos: Importar um componente remoto com Module Federation Passar dados para esse componente via props Exibir esses dados no MF Provider como se tudo estivesse rodando no mesmo app Acompanhe AQUI como ficou o resultado final. No próximo artigo, vou mostrar como esse padrão pode ser estendido para eventos e callbacks entre MF Consumer e MF Provider (ex: o usuário clica em algo no Provider e o Consumer reage). 💬 Curtiu? Me conta nos comentários como você está usando MF ou se está considerando aplicar na sua stack. Microfrontend with React (e-book)  ( 4 min )
    Containerized Symfony & Vue.js environment with DDEV
    For the past year or so, DDEV has been my go-to tool for setting up a development environment. With a simple .yaml file, this nifty tool is capable of providing a containerized workbench with PHP, a MariaDB/PostreSQL database, and Mailpit. It's perfect for anything from WordPress to the most complex Symfony app. However, out of the box it's not tailored to be used alongside Node. Granted, it does come bundled with Node pre-installed, but if you want to use your PHP backend with a TypeScript frontend, it requires a tiny bit of configuration. This is what this article is about. It is inspired by Andy Blum's blog post over at Lullabot. My approach is similar but a bit simpler. My web stack of choice is Symfony as an API (either RESTful or using GraphQL) and a frontend using Vue.js. I used to …  ( 6 min )
    [Parte 2] — O que é Module Federation e que problema ele resolve?
    No meu artigo anterior, mostrei como montei um projeto com Micro Frontends usando Rsbuild, Module Federation, pnpm e Lerna , tudo rodando num monorepo. Agora, quero dar um passo além e explicar o “porquê” dessa escolha. É uma forma de compartilhar código entre diferentes aplicações em tempo de execução. Funciona como se um app pudesse importar um componente diretamente do outro — sem instalar, copiar ou duplicar código. Exemplo real no meu repositório: 📦 mf_provider(chamo de componente filho): expõe um componente Button 📦 mf_consumer_(_chamo de componente pai): consome esse mesmo Header, remotamente, sem precisar tê-lo no código local ✅ Evita reescrever os mesmos componentes em diferentes apps (pelo menos tenta) ✅ Permite deploys independentes (independência de times) ✅ Melhora a escalabilidade de grandes projetos ✅ Facilita refatorações e testes A/B isolados ✅ Acelera o desenvolvimento com reuso real de UI e lógica “Você não precisa de Micro Frontends… até precisar.” Nem todo projeto precisa disso. 🔸 Se o projeto é pequeno e centralizado, pode ser complexidade desnecessária 🔸 Se as equipes compartilham tudo e fazem deploy juntos, MF talvez seja overkill 🔸 Se o bundle não é um problema, pode usar libs compartilhadas internas 🚀 Quer ver isso funcionando de verdade?

    Refactor-First, Feature-Last: Conversing with Code
    Two months into my no-code-writing development experiment, I've started to reflect on what I've gained and lost in the process. There are clear wins: faster prototyping, more exploratory design conversations before touching code, and almost no actual coding (which is a huge relief, I'm more of an organize-ideas person, not a coder). I followed the tools' lead intentionally, curious to see what they had to offer. But in doing so, I slipped back into early-career patterns, prioritizing feature work and not handling code smells up front. I lost my Monday-ness. I'm a code whisperer. A wild west code wrangler. The one who could reshape entire systems by refactoring in their sleep. In this post, I want to return to the process that made that kind of work possible. The one that helped me grow fro…  ( 7 min )
    So You Want to Learn Backend
    It's me. I want to learn back end. If you do too, maybe I can help you out. Lets back up a little bit. I am a front end web developer, and I have noticed a flaw in my peers. It is not always present, but it is certainly prolific. For a job that is existentially deep learning, there is very little focus on how we learn. As a college educator this has always stuck out to me. We know we want to learn backend. But how do we learn back end? That's what I want to help you with. In my humble opinion our job isn't necessarily to write code. Our job is to provide value to others by solving problems. Code just happens to be the most effective tool for that. I find it's helpful to approach the the question of how do we learn backend like any other problem. Let me share one of the most valuable tools…  ( 9 min )
    Implementing API Header Versioning in node.js 🍗
    API versioning via headers is a powerful way to evolve your API without breaking existing clients.  Here's a deep dive into what it is, why you'd use it, and a step-by-step guide to implementing it in Express. 1.Separation of Concerns Versioning in headers keeps your URL space clean - clients still call /users instead of /v1/users or /v2/users. 2.Content Negotiation HTTP was designed around content negotiation. You can leverage the Accept header or a custom header (e.g. X-API-Version) to tell your server which variant of the response to emit. 3.Granular Control You can version on a per-resource or even per-field basis depending on header values. Strategy How It Works Pros Cons Accept Header Accept: application/vnd.myapp.v1+json Follows HTTP spec; cache-friendly Clients must set corr…  ( 7 min )
    Micro Frontends + Rsbuild + Module Federation em um Monorepo? Temos!
    💡 Quer estudar, prototipar ou estruturar um projeto com MF (Microfrontend) de forma modular e performática? Nos últimos dias, mergulhei em um experimento que pode facilitar (e muito!) a vida de quem trabalha com micro frontends no dia a dia. 🎯 Criei um repositório open source usando: Rsbuild (alternativa moderna e rápida ao Webpack) Module Federation para isolar e compartilhar componentes entre apps pnpm + Lerna pra orquestrar tudo de forma leve e organizada 📂 Estrutura simples, mas poderosa: apps/mf_provider: expõe componentes apps/mf_consumer: consome via Module Federation Tudo rodando em paralelo com pnpm dev 🔗 Confere lá e, se curtir, arrocha um like ou manda feedback! Repositório no Github O pnpm tem um recurso bem legal chamado Catalogs. Ele serve para definir versões de dependências como constantes, que podem ser reutilizadas nos módulos internos dentro do package.json de cada projeto. Exemplo: # pnpm-workspace.yaml # Define a catalog of version ranges. catalog: react: "^18.3.1" react-dom: "^18.3.1" # Nos módulos internos, consigo reutilizar a versão definida no pnpm-workspace.yaml "dependencies": { "react": "catalog", "react-dom": "catalog" } Outra curiosidade bem legal é a praticidade que o Lerna oferece na criação de um monorepo, permitindo executar vários apps juntos de forma paralela com um único comando, como no exemplo abaixo: "dev": "lerna run --parallel dev", Rsbuild + Module Federation se mostrou extremamente simples de estruturar e entender, especialmente se comparado ao uso do plugin com Webpack.

    AI Killed Your Competitive Edge. Here's What Will Save It.
    In 2015, launching a SaaS product that actually worked was impressive. You didn't need a community. You just needed to build it. But today? Building is easy. Too easy. AI writes your backend. Execution is no longer your moat. Everyone has the same tools. You're not competing on what you build. how it feels to use your product. That's the new edge: emotional connection. Not because it's nice to have only thing left that's hard to copy. Let's be honest. Most SaaS products today are perfectly functional. You sign up, click around, maybe submit feedback, then never hear back. It's all so… sterile. The most beloved products don't just solve a problem. alive.

    What Happens When AI Becomes the Client?
    Most APIs were built for humans. We wrote docs assuming someone would read them. We wrapped our endpoints in auth flows and user interfaces. We expected a person, or maybe a service, on the other side. But that’s already changing. AI models are now consuming APIs directly. Not as passive data readers, but as active participants. They parse user intent, synthesize context, and trigger backend actions. They're not just clients. They're intermediaries. And that changes everything. When models call APIs, natural language stops being enough. We like to imagine that models “understand” prompts, but in practice, they just compute probabilities over sequences of text. They don’t grasp nuance the way humans do. A tiny shift in phrasing can derail the whole interaction. That makes coordination betwe…  ( 4 min )
    Leaders Are Overlooking This Crucial Factor in AI Readiness
    The 2025 McKinsey report on AI in the workplace reveals an important data point. Employees are more prepared for AI than most leaders realize. According to the report, 94% of employees have some familiarity with generative AI tools. Most execs estimated 4% of their teams already use AI heavily at work. However, the real figure is 12%, three times higher. Even skeptics are on board. The report labels cautious employees as "Gloomers" (37% of the workforce), who want tight AI oversight, and "Doomers" (4%), who distrust AI outright. Yet 80% of Gloomers and 50% of Doomers say they’re comfortable using AI at work. That shows widespread readiness, not just enthusiasm from the usual suspects. Employees clearly crave tools and skills, but too many leaders hesitate. Some chase hype, while others f…  ( 6 min )

    Derive TypeScript Types from Mongoose Schemas 🌿
    When working with Mongoose and TypeScript, two helper types make your life much easier: /** * Extracts the “plain” shape of your schema— * just the fields you defined, without Mongoose’s built-in methods or `_id`. */ export type User = InferSchemaType; /** * Represents a fully “hydrated” Mongoose document: * your fields plus all of Mongoose’s methods and metadata * (e.g. `_id`, `save()`, `populate()`, etc.). */ export type UserDocument = HydratedDocument; export const userModel = model("user", userSchema); InferSchemaType • Produces a pure TypeScript type from your schema definition. • Use it whenever you need just the data shape (e.g. DTOs, service inputs/outputs). HydratedDocument • Wraps your base type T with Mongoose’s document helpers. • Use it for any function that deals with real, database-backed For example, in a repository interface you might write: export interface IUserRepository { findOneByEmail(email: string): Promise; findById(id: Types.ObjectId): Promise; create( createUserDto: Pick, ): Promise; } Here, each method clearly promises a “live” Mongoose document (with built-in methods) while elsewhere you can rely on User for pure data shapes—keeping your boundaries and types crystal clear.

    Predicting Crop Yield using Machine Learning
    Sure! Here's a DEV.to style blog post for your project Crop Yield Prediction: An ML project to empower smarter agriculture decisions GitHub Repo → Agriculture remains the backbone of the Indian economy, yet farmers still face unpredictable yields due to varying environmental and input conditions. To tackle this issue, I built a machine learning model that predicts crop yield based on historical and input-based features. This project is simple, beginner-friendly, and practical. "How can we accurately predict crop yield based on inputs like rainfall, fertilizer, and pesticide use?" Farmers often rely on experience or guesswork. This model helps bring data-driven decision-making to the field. The dataset includes: Area Production Crop Year Rainfall Fertilizer Pesticide 📌 Categorical features are label-encoded for model compatibility. Python 🐍 Pandas & NumPy Scikit-learn Matplotlib (optional for plots) I trained and evaluated three regression models: Linear Regression Random Forest Regressor Gradient Boosting Regressor ✅ Best performer Evaluation Metrics: R² Score Adjusted R² RMSE Gradient Boosting gave the highest R² score on the test set and was chosen as the final model. The script allows users to input values for the features and get instant yield predictions.

    Demystifying Entity Transaction & Flush in Spring Boot: Are You Using It Right?
    When working with Spring Boot and JPA, understanding how transactions and the 𝗳𝗹𝘂𝘀𝗵() operation interact can make or break your application's data consistency and performance. Yet, I often see even experienced developers overlook the nuances! Many believe that committing a transaction is the only way to persist changes to the database. However, the 𝗳𝗹𝘂𝘀𝗵() method forces the persistence context to synchronize with the underlying database immediately-without ending the transaction. This can be a game-changer for scenarios where you need to validate constraints or trigger database actions before the transaction completes. But here’s the catch: improper use of 𝗳𝗹𝘂𝘀𝗵() can lead to unexpected behaviors, performance overhead, or even data inconsistencies if not handled carefully. It's crucial to know when and why to use it, especially in complex microservices or batch processing environments. How do you approach transaction management and flushing in your Spring Boot projects? Have you ever faced a tricky bug or performance issue related to this?

    Level Up Your Data Skills: 10 Essential SQL Books for Devs & Data Scientists
    Disclosure: This post includes affiliate links; I may receive compensation if you purchase products or services from the different links provided in this article. Hello friends, SQL (Structured Query Language) is one of the most essential skills for any Software Engineer. I would rate this skill as similar to system design and coding. If you are a professional programmer, it doesn't matter whether you are a Java, Golang, or .NET developer; you are bound to write SQL queries. Since the database is an integral part of any modern Java or Web application, the Interviewer always preferred candidates with excellent SQL skills. Now, the big question comes: How can a programmer learn SQL? Is knowing how to query a table enough? If you remember insert, update, delete, and select, then are you a…  ( 9 min )

    PostgreSQL vs. Qdrant for Vector Search: 50M Embedding Benchmark
    Vector search is becoming a core workload for AI-driven applications. But do you really need to introduce a new system just to handle it? We ran a performancebenchmark to find out: comparing PostgreSQL (using pgvector + pgvectorscale) with Qdrant on 50 million embeddings. Sub-100ms query latencies 471 queries per second (QPS) on Postgres—11x higher throughput than Qdrant (41 QPS) Head to the full write-up for a deep dive into our vector database comparison. At 99% recall, Postgres delivers sub-100ms query latencies and handles 11x more query throughput than Qdrant (471 QPS vs. Qdrant’s 41 QPS). The results show that thanks to pgvectorscale, Postgres can keep up with specialized vector databases and deliver as good, if not better performance at scale. Learn more about why Postgres wins for AI and vector workloads. How? We built pgvectorscale to push Postgres to its limits for vector workloads—without compromising recall, latency, or cost-efficiency. It turns your favorite relational database into a high-performance vector search engine. ✅ No extra systems. ✅ No new query languages. ✅ Just Postgres. We used RTABench to run a transparent, reproducible evaluation—designed for real-world, high-scale workloads. Curious about the architecture behind it all? 👉 Read our whitepaper on building Timescale for real-time and AI workloads It dives into how we engineered Timescale to handle time-series, vector, and relational data—all in one Postgres-native platform.

    My Understanding of DevOps Engineering
    What is DevOps? DevOps, as the name suggests, combines Development and Operations into a unified approach. A DevOps Engineer orchestrates the entire journey of an application: planning, coding, building, testing, releasing, deploying, and monitoring. This comprehensive process ensures applications work seamlessly for end-users and integrate properly with other services. I see DevOps Engineers as master planners who understand the complete Software Development Life Cycle (SDLC). Success in this role requires both technical expertise and strong communication skills. Communication becomes crucial especially when coordinating across different teams – from developers to stakeholders. Planning begins with constructive thinking about the development and production environments where code will b…  ( 5 min )
    Running Model Context Protocol (MCP) Servers on containers using Finch
    I was chatting with AWS Hero Matt Lewis on the topic of how to run MCP Servers via a container image, and realised that I had not actually tried this yet. So this post was inspired by that conversation, and I hope it helps anyone else who is looking to try it out. In a previous post I introduced how Amazon Q CLI now supports Model Context Protocol (MCP) (check out Configuring Model Context Protocol (MCP) with Amazon Q CLI for more details). This post will build on that and show you how to run MCP Servers via container images. As I switched to using Finch from Docker back in 2024, I will be using that - this means if you are using something different to Docker, like Podman for example, you should be able to follow along and use that tool too.

    Demystifying HTTP for Web Developers — Part 1
    What is HTTP and How a Request Travels Across the Web HTTP is the foundation of everything we build and interact with on the web — whether it’s a static website, a complex Single Page Application (SPA), a RESTful API, or a modern mobile app. Every user action that triggers data exchange — from submitting a login form to loading an image — ultimately depends on HTTP. Despite this, many developers treat HTTP as a black box: something that “just works” behind the scenes. While abstraction is useful, serious web developers must move beyond it. Understanding how HTTP actually operates — from how requests are structured, to how connections are established, to how responses are transmitted — is essential for building high-quality, secure, and performant applications.

    Interfaces in java
    🧵 Interfaces in Java, explained like you're 5! 1️⃣ Imagine a Pizza Menu 🍕 You walk into a pizza place and see a menu. The menu promises what pizzas they offer—but doesn’t make them yet. An interface in Java is like that menu: it defines what a class should do, but not how! The menu says: "All pizzas must have cheese 🧀" "All pizzas must be bakeable 🔥" Any chef (class) who follows this menu must fulfill these rules! In Java, we call this "implementing an interface." 3️⃣ Multiple Menus, One Chef! A chef can follow multiple menus (interfaces): Italian food menu 🍝 Fast food menu 🍔 Similarly, a Java class can implement many interfaces at once! (Unlike inheritance, where you only get one parent.) 4️⃣ But… What If the Chef Cheats? 😱 If a chef says, "I’ll follow the pizza menu!" but doesn’t add cheese… BIG PROBLEM! Java won’t allow this—it forces the class to implement every method in the interface, or the code won’t compile! What if some pizzas usually have tomato sauce, but not always? Interfaces can now provide default methods—like a "standard recipe" that chefs can override if they want! java interface Pizza { default void addSauce() { System.out.println("Adding tomato sauce!"); } }  ( 3 min )

    Why ARP Matters !!!
    We need ARP (Address Resolution Protocol) to enable communication between devices on a local network. Specifically, ARP is used to map an IP address (logical address) to a MAC address (physical address), which is necessary for data transmission at the data link layer. ARP is a Layer 2 protocol used in IPv4 networks to map a known IP address to its corresponding MAC (Media Access Control) address. While IP addresses help devices find each other logically, MAC addresses are what Ethernet networks use to actually deliver packets. ARP acts as the translator between these two. IP works at Layer 3 (Network Layer) but to actually send data over Ethernet (Layer 2), the system needs the MAC address of the destination device. When a device wants to communicate with another device on the same netwo…  ( 5 min )

    Scripting Series – Part 4 of 8
    Welcome to part 4 in the series of shell scripting. Today we will look at a script that goes through an array with complex values. Complex values such as spaces, apostrophes, and quotes. Scripting is the process of writing a set of instructions in a programming or scripting language to automate tasks that would otherwise be done manually. In the context of shell scripting, these instructions are written for the command-line shell, allowing users to perform complex operations - like file management, backups, or software installations - with just a single script execution. It's a powerful tool for saving time and ensuring consistency in system administration and development workflows Create the script in VIM, complex_list.sh Write and save the script in VIM. We can check whether it has been created by doing ls -ltrh. Give the permission so the script can be executed. If we then do a ls –ltrh we can see the script has gained a green colour, meaning that it is now executable. Output after executing the script by using the command ./ Stay tuned, part 5 in the series coming tomorrow!

    🚀 Introducing SaaSLaunchpad: A Next.js Boilerplate Built for Freedom, Not Lock-In
    Excelorithm, we build custom software solutions for startups, SMEs, and enterprise clients alike. And as the technical head here, I’ve seen a recurring pain point — many teams, including our own, spend way too much time setting up the basics of a SaaS product: authentication, subscriptions, dashboards, role management, notifications... Sure, there are tons of SaaS starter kits out there, both free and premium. They promise speed — and often deliver — but usually at a hidden cost: vendor lock-in. Many popular boilerplates rely on proprietary services, paid APIs, or tightly coupled ecosystems. That might be fine early on, but over time it limits your freedom, raises your costs, and ties you to someone else’s roadmap. That’s why we built SaaSLaunchpad — a free, open-source Next.js SaaS starter kit with zero paid tool dependencies and no vendor lock-in. 🧠 Why SaaSLaunchpad? Built with: 🔍 How It Compares Feature SaaSLaunchpad Vercel SaaS Starter SupaStarter ShipFast Open Source ✅ Yes (MIT) ✅ Yes (MIT) ❌ Paid License ✅ Partially Authentication ✅ NextAuth.js ✅ Auth.js ✅ Supabase Auth ✅ Clerk/Auth0 (Paid) Payments (Stripe) ✅ Full + Portal ✅ Basic Checkout ✅ Limited ✅ With 3rd-party lock-in Role-based Access (RBAC) ✅ Built-in ❌ No ✅ With Supabase ✅ Custom Vendor Lock-In ❌ None ✅ Vercel/Upstash ✅ Supabase ✅ Clerk/Auth0/Vercel Email Templates ✅ Nodemailer ❌ No ❌ No ✅ With restrictions Notifications ✅ Firebase/OneSignal ❌ No ❌ No ❌ No UI Framework ✅ shadcn/ui ✅ Tailwind UI ✅ Tailwind ✅ Custom Free to Use End-to-End ✅ 100% ✅ Mostly ❌ No (Premium only) ❌ Some paid features 👥 Built by Developers, for Developers 🧑‍💻 Check it out on GitHub: 🌐 Learn more about us: excelorithm.com 💬 Let’s Talk 💡 Got a feature idea or found a bug?

    Catalysis Node Operators Explained: The Backbone of a Scalable Web3 Ecosystem
    INTRODUCTION: But exactly is the purpose of the Node Operators in the Catalysis Ecosystem? well let's get into that now. They power the services (AVSs) by doing important technical tasks. They also help protect the network by locking up funds (called staking)—this keeps them honest. If they do something wrong, they can lose money so they have a strong reason to act fairly. I'm pretty sure at this point you can fairly understand why they are called the backbone of the network. Basically without them nothing would work. HOW DOES CATALYSIS WORK IN RELATION TO THE NODE OPERATORS? Normally, running these services on many platforms is complicated and expensive. Catalysis simplifies this by giving them one tool (Catalyst-CLI) to manage everything in one place. Think of the (Catalyst-CLI) li…  ( 4 min )
    Send Node.js logs from Docker to Grafana Cloud with Alloy
    tl;dr: alloy config, docker-compose. Any service that's meant to live more than couple of weeks eventually reaches the stage where you feel the need to properly monitor it.

    838. Push Dominoes
    838. Push Dominoes Difficulty: Medium Topics: Two Pointers, String, Dynamic Programming There are n dominoes in a line, and we place each domino vertically upright. In the beginning, we simultaneously push some of the dominoes either to the left or to the right. After each second, each domino that is falling to the left pushes the adjacent domino on the left. Similarly, the dominoes falling to the right push their adjacent dominoes standing on the right. When a vertical domino has dominoes falling on it from both sides, it stays still due to the balance of the forces. For the purposes of this question, we will consider that a falling domino expends no additional force to a falling or already fallen domino. You are given a string dominoes representing the initial state where: dominoes[i] = …  ( 25 min )

    Spring JPA - @EntityGraph
    By default, Spring Data JPA loads related data lazily, which can cause the N+1 problem — one query for the main data and more for each related item. @EntityGraph annotation fixes this by letting you load related data in a single query, without changing your entity mapping. It’s simple, improves performance, and avoids writing custom JOIN FETCH queries. Let’s say you have a Post entity that references an Author. Entities @Entity public class Post { @Id private Long id; private String title; @ManyToOne(fetch = FetchType.LAZY) private Author author; } @Entity public class Author { @Id private Long id; private String name; } Repository public interface PostRepository extends JpaRepository { // attributePaths specifies related entities to eagerly load @EntityGraph(attributePaths = {"author"}) List findAll(); } Now, if you create a simple controller to return all posts and have SQL logging enabled, you'll see the queries printed in the console. With @EntityGraph, only one query runs to fetch both the post and its author. Without it, multiple queries are executed — one for the posts and one for each author — which is the N+1 problem. ✅ Using @EntityGraph Only one query — fast and efficient. select p.id, p.title, a.id, a.name from post p left join author a on p.author_id = a.id 🚨 Not Using @EntityGraph N+1 queries — slow and wasteful. select * from post; select * from author where id = ?; select * from author where id = ?;  ( 3 min )

    Best Alternative to pprint: Introducing SetPrint for Better Python Data Formatting
    Issues with Existing Formatting Tools When working with data structures like lists or NumPy arrays in Python, the standard print or pprint, or even external tools like rich, often fail to provide a clear view of the entire structure, especially when dealing with multi-dimensional arrays or deeply nested data, making it easy to lose track of which element corresponds to which. Let's consider the following example as an illustration. sample = [ {"user": {"id": 1, "name": "Alice", "scores": [95, 88, 76]}}, {"user": {"id": "002b", "name": "Bob", "scores": [72, 85, 90]}}, {"bug_user": {"id": [3], "name": "Charlie", "scores": [100, [50, 40], 70]}}, ] — The “Pitfalls” of Data Structures Python's lists, dictionaries, and NumPy arrays are fine to work with for simple structures.…  ( 5 min )

    Stars align for Bitcoin rally to $100K, but futures traders exercise caution — Here’s why
    Key takeaways: BTC hit $97,900 due to soaring institutional investor demand, but futures pricing shows traders aren't confident in a sustained rally. Macroeconomic risks and global trade tensions cap bullish sentiment despite $3.6 billion in spot BTC ETF inflows. BTC options lean bullish, suggesting big players expect upside, but their caution keeps leverage use low. Bitcoin (BTC) broke out of a tight trading range between $93,000 and $95,600 on May 1, following six days of limited movement. Despite reaching its highest price in ten weeks at $97,930, sentiment remains neutral according to BTC derivatives indicators. This price action has occurred alongside significant net inflows into US spot exchange-traded Bitcoin funds (ETFs). Some of the disappointment among traders can be attribut…
    Pro-crypto senator pushes back on Trump's memecoin dinner — Report
    Senator Cynthia Lummis and at least one other Republican in Congress are reportedly critical of US President Donald Trump for offering the top holders of his memecoin a dinner and White House tour. According to a May 2 CNBC report, Lummis said the idea that the US president was offering exclusive access to himself and the White House for people willing to pay for it “gives [her] pause.” She wasn’t the only member of the Republican Party to be critical of Trump’s memecoin perks, announced on April 23, roughly three months after the then-president-elect launched the TRUMP token.   “I don’t think it would be appropriate for me to charge people to come into the Capitol and take a tour,” said Republican Senator Lisa Murkowski, according to NBC News. Despite Lummis’ reported “pause” over the p…
    Ethereum’s era of crypto dominance is over — LONGITUDE panel
    Ethereum’s relative dominance among layer-1 (L1) blockchain networks has declined, resulting in an “open race” to become the leading Web3 platform, according to Alex Svanevik, CEO of data service Nansen. “If you’d asked me 3–4 years ago whether Ethereum would dominate crypto, I’d have said yes,” Svanevik said during a panel discussion at the LONGITUDE by Cointelegraph event. “But now, it’s clear that’s not what’s happening.” Ethereum is still the most popular L1 network. According to data from DefiLlama, its roughly $52 billion in total value locked (TVL) represents 51% of cryptocurrency residing on blockchain networks. However, Ethereum’s dominance has diminished sharply since 2021, when the L1 controlled as much as 96% of aggregate TVL, the data shows.  Panelists at the LONGITUDE by Coin…
    Most shops in Cannes to accept crypto by summer this year — Web3 exec
    Merchants in Cannes, France, the site of the international Cannes Film Festival, are set to begin accepting crypto payments by summer this year in an effort to attract clientele with high disposable income by modernizing the city's commercial payment ecosystem. According to Artem Shaginyan, founder and head of strategy of Web3 payment company Lunu Pay, the Cannes municipal government is aiming for a 90% adoption rate among local merchants. The executive also told Cointelegraph: "This is a big signal. When a city like Cannes, known globally for culture and commerce, starts integrating crypto at scale, it shows that Web3 payments aren’t just a niche thing anymore. It’s about proving that crypto can work in everyday settings, not just online or in theory." In February, Cannes Mayor David Lisn…
    Crypto skeptic to release SBF, Mashinsky interviews in documentary
    Ben McKenzie, an actor known for his roles on television shows including Gotham and The OC, will make his directorial debut in a scathing documentary about cryptocurrency. According to an April 29 Deadline report, McKenzie wrote, directed, and produced the documentary Everyone Is Lying To You For Money, set to premiere at SXSW London in June. The film features footage from 2022 of former FTX CEO Sam “SBF” Bankman-Fried and former Celsius CEO Alex Mashinsky before their respective companies folded.  “Why is the false story of crypto still spreading?” said McKenzie, according to Deadline. “That’s the question I set out to answer with this film.” Sam Bankman-Fried (left) with Ben McKenzie (right).

    Bitcoin data, macroeconomic charts point to new BTC all-time high ‘in 100 days’ — Analysts
    Key Takeaways: Analyst predicts a low VIX ( Bitcoin network economist Timothy Peterson raised Bitcoin’s (BTC) chances of hitting a new high in 100 days, and he maintains an optimistic outlook in 2025.  In an analysis shared on X that ties BTC’s price action to the CBOE Volatility Index (VIX) —an indicator that measures 30-day market volatility expectations — the analyst pointed out that the VIX index has dropped from 55 to 25 over the past 50 trading days. A VIX score below 18 implied a “risk-on” environment, favoring assets like Bitcoin.  Peterson’s model, which had a 95% tracking accuracy, predicted a $135,000 target within the next 100 days if the VIX remains low. This aligns with Bitcoin’s sensitivity to market sentiment, as a low VIX reduces uncertainty, encouraging investment in ri…
    XYO Network tops 10M DePIN nodes — Co-founder
    XYO Network has onboarded more than 10 million nodes to its decentralized physical infrastructure network (DePIN), co-founder Markus Levin told Cointelegraph in an interview. The nodes mostly comprise human users who provide data in exchange for rewards via the network’s mobile application, COIN. “The vast majority of our 10 million nodes are mobile users, but some are IoT devices like smart speakers,” Levin told Cointelegraph.  Approximately 80% of XYO’s users are non-crypto natives who are participating in Web3 for the first time, he added. They include truckers, rideshare drivers, delivery people, and nurses among others, Levin said, adding that “95% convert after onboarding through the COIN app.” XYO launched a layer-1 blockchain network in January.

    Bitcoin ETFs, gov’t adoption to drive BTC to $1M by 2029: Finance Redefined
    The cryptocurrency market continued its recovery in the past week as the total crypto market capitalization breached the $3 trillion mark for the first time since the beginning of March. Bitcoin (BTC) rose to an over two-month high of $97,300 last seen at the end of February, before the “Liberation Day” tariffs announcement in the US, bolstering analyst predictions for a rally driven by “structural” institutional and exchange-traded fund (ETF) inflows into the world’s first cryptocurrency. Risk appetite continued rising among crypto investors, as Chinese state-linked news outlets indicated that the Trump administration has quietly contacted Beijing to discuss tariff reductions.

    Price predictions 5/2: BTC, ETH, XRP, BNB, SOL, DOGE, ADA, SUI, LINK, AVAX
    Key points: Bitcoin trends toward $100,000. Will bears sell at this level? Altcoins are trading above their respective support levels, suggesting that an altcoin rally is brewing. Bitcoin’s (BTC) tight consolidation resolved in favor of the bulls with a break above the $95,000 barrier on May 1. The bulls are trying to push the price to the psychologically crucial level at $100,000, which may again witness a tough battle between the bulls and the bears.  Veteran trader Peter Brandt sounded positive when he said in a post on X that Bitcoin could rally to the $125,000 to $150,000 range by August or September 2025 if it manages to regain its broken parabolic slope. However, Brandt cautioned that the rally could be followed by a sharp correction of more than 50%. Crypto market data daily vie…
    Why Grayscale’s Bitcoin Trust still dominates ETF revenue in 2025
    In the annals of financial history, few institutions have faced the tempests of competition with the steadfast resolve of Grayscale Bitcoin Trust (GBTC). Born in 2013 as a private placement, GBTC pioneered regulated Bitcoin investment, granting investors access to Bitcoin’s (BTC) meteoric rise without the perils of digital wallets or unregulated exchanges. On Jan. 11, 2024, it transitioned into a spot Bitcoin ETF following a landmark victory against the SEC. This marked a pivotal moment with the SEC’s view that ETFs can offer lower expense ratios and enhanced tax efficiency compared to traditional funds.  Even still, GBTC’s financial resilience shines, generating $268.5 million in annual revenue, surpassing the $211.8 million of all other US spot Bitcoin ETFs combined, despite losing over …
    Bitcoin is a matter of national security — deputy CIA director
    The US Central Intelligence Agency is increasingly incorporating Bitcoin (BTC) as a tool in its operations, and working with the cryptocurrency is a matter of national security, Michael Ellis, the agency’s deputy director, told podcast host Anthony Pompliano. In an appearance on the market analyst and investor’s show, Ellis told Pompliano that the intelligence agency works with law enforcement to track BTC, and it is a point of data collection in counter-intelligence operations. Ellis added: "Bitcoin is here to stay — cryptocurrency is here to stay. As you know, more and more institutions are adopting it, and I think that is a great trend. One that this administration has obviously been leaning forward into." "It's another area of competition where we need to ensure the United States is we…
    Bitcoin hits new 10-week high as Trump demands rate cut on US jobs beat
    Key points: The US labor market is “still holding up” as nonfarm payrolls data comes in higher than expected. Bitcoin and stocks head higher as US President Donald Trump repeats calls for the Fed to lower interest rates. BTC price action may spark a “liquidity grab” above $97,000, a trader warns.

    Free speech is at risk without decentralized, open-source technology
    Opinion by: Chris Jenkins, adviser to Pocket Network Tim Berners-Lee’s vision of the World Wide Web is dead. Instead of an open and accessible global information system, the web is controlled by centralized global data conglomerates, which don’t just restrict free speech but also monetize your data as a price of entry. Web2 firms have built walled gardens with massive information asymmetry between companies and users. Blockchain-based decentralized tech challenges the status quo, offering an alternative to Web2’s closed-source infrastructure.  It enables developers and engineers to build a censorship-resistant and accessible open-data web to champion the cause of free speech. Open-source technology creates a paradigmatic shift in a fair and inclusive internet where centralized web companie…
    Ether more ‘like a memecoin,’ says trading firm as ETH drops 45% YTD
    As Ether’s price has struggled in the first quarter of 2025, a US-based investment adviser firm, Two Prime, has dropped support for ETH and adopted a Bitcoin-only strategy. After lending $1.5 billion in loans both in Bitcoin (BTC) and Ether (ETH) over the past 15 months, Two Prime decided to ditch ETH to focus solely on BTC asset management and lending, the firm announced on May 1. “ETH’s statistical trading behavior, value proposition, and community culture have failed beyond a point that is worth engaging,” Two Primes stated. The firm’s shift to a Bitcoin-only approach comes as ETH has lost 45% of its value year-to-date, with some optimists speculating that ETH is potentially close to the bottom and reversing its negative trend soon. “Ether no longer trades predictably” “As an algorithmi…
    Moon soon? XRP's strongest spot premium aligns with 70% rally setup
    Key takeaways: XRP’s strongest spot premium phase suggests real buying demand, not just speculative futures trading. The number of XRP addresses holding ≥10,000 tokens has steadily climbed, even during recent price pullbacks. A falling wedge pattern points to a possible breakout toward $3 to $3.78, with up to 70% upside if confirmed. XRP (XRP) is experiencing its strongest sustained phase of spot premium in history, a period where the spot market has been consistently trading at stronger levels compared to perpetual futures. XRP’s 350% rally is backed by real demand Since 2020, most major XRP price peaks happened when the perpetual futures market was leading, noted market analyst Dom in his May 2 post on X. XRP’s futures prices being higher than spot signaled excessive speculation…
    Bitcoin unsure as recession looms, US-China tariff talks kick off
    Bitcoin’s recovery to its all-time high may be threatened by rising recession fears, which could ease if the United States and China begin tariff negotiations this month, research analysts told Cointelegraph. Appetite for global risk assets such as Bitcoin (BTC) may take another hit, with analysts from Apollo Global Management predicting a recession by the summer. “Apollo predicting Summer Recession: Sharpest decline in earnings outlook since 2020,” cross-asset analyst Samantha LaDuc wrote in an April 26 X post. The progress on the tariff negotiations may be the most significant factor impacting a potential recession and Bitcoin’s price trajectory, according to Aurelie Barthere, principal research analyst at crypto intelligence platform Nansen.

    UK regulator moves to restrict borrowing for crypto investments
    The United Kingdom’s financial regulator, the Financial Conduct Authority (FCA), plans to stop retail investors from borrowing money to fund their crypto investments. According to a May 2 Financial Times report, the ban on borrowing to fund crypto purchases is one of the upcoming crypto rules by the FCA. David Geale, FCA executive director of payments and digital finance, told the FT that “crypto is an area of potential growth for the UK, but it has to be done right.” He added: “To do that we have to provide an appropriate level of protection.” Geale denied claims that the FCA is hostile to the crypto industry. Instead, he explained that he views the industry as offering high-risk investments with less consumer protection. “We are open for business,“ he said. The interview follows the FCA …
    Are Donald Trump’s tariffs a legal house of cards?
    On Wednesday, speaking from the White House, US President Donald Trump suggested that families scale back on gifts this year. Asked about his tariff program, the president remarked, “Somebody said, ‘Oh, the shelves are gonna be open. Well, maybe the children will have two dolls instead of 30 dolls, and maybe the two dolls will cost a couple of bucks more.’” But the toy stores where those dolls are sold might have something to say about it.  Earlier in the week, Mischief Toy Store in St. Paul, Minnesota joined a growing number of American small businesses suing the president over his emergency tariff plan. Throughout April, a groundswell of lawsuits led by 13 states further challenged Trump’s ambitious tariff program. Their success or failure rests on hundreds of years of judicial policy an…
    KuCoin to reenter South Korea after securing key markets: CEO
    Crypto exchange KuCoin said that it may reenter South Korea after its platform was blocked in the country.  On March 21, South Korean regulators ordered Google Play to block access to exchanges that were not compliant with the requirements needed to operate in the country. On April 11, South Korea’s Financial Services Commission (FSC) ordered the Apple Store to block unregistered crypto exchanges.  KuCoin was among those affected by the country’s crackdown on unregistered platforms that were previously available. While the platform is now unavailable to South Koreans, it has not fully abandoned the jurisdiction.  In an exclusive interview with Cointelegraph, KuCoin’s newly appointed CEO, BC Wong, said that the crypto exchange has plans to reenter the country.  Wong (left), KuCoin EU CEO Ol…
    European Union to ban anonymous crypto and privacy tokens by 2027

Under the new Anti-Money Laundering Regulation (AMLR), credit institutions, financial institutions and crypto asset service providers (CASPs) will be prohibited from maintaining anonymous accounts or handling privacy-preserving cryptocurrencies, such as Monero (XMR) and Zcash (ZEC). “Article 79 of the AMLR establishes strict prohibitions on anonymous accounts [...]. Credit institutions, financial institutions, and crypto-asset service providers are prohibited from maintaining anonymous accounts,” according to the AML Handbook, published by European Crypto Initiative (EUCI).

    Circle’s Refund Protocol, explained: Bringing refunds to stablecoin payments
    Why are refunds important in stablecoin payments? Anyone who has used traditional payment systems will likely be familiar with refunds and chargebacks. If a purchase goes wrong, like receiving damaged items or not receiving the product at all, the payer can file a complaint with the seller to recover their funds. This process of refunds builds trust between payers and sellers, ensuring secure transactions for both sides. However, stablecoin transactions differ significantly. Unlike credit cards or PayPal, stablecoin payments are generally irreversible. Once sent, the payment is final, with no standard way to dispute or reverse it if issues arise, which can make payers wary of using stablecoins for daily purchases. This highlights the importance of …
    Bitcoin hodler unrealized profits near 350% as $100K risks sell-off
    Key points: Bitcoin long-term holders are about to hit a level of unrealized profit, which has traditionally caused them to sell. That level coincides with the return to a six-figure BTC price. Order book data suggests that bulls may not succeed in keeping the upside going. Bitcoin (BTC) risks a “notable increase” in selling from its older investors if price rises further, warns onchain analytics firm Glassnode.

    Movement Labs suspends co-founder following MOVE market turmoil
    Movement Labs confirmed the suspension of its co-founder, Rushi Manche, following controversies over a market maker deal that he brokered. Movement announced the suspension of Manche in a May 2 X post, explaining that the “decision was made in light of ongoing events.” The decision follows Coinbase's recent decision to suspend the Movement Network (MOVE) trading, citing the token’s failure to meet its listing standards. Source: Movement The suspension came after a recently announced third-party review requested by the Movement Network Foundation into an agreement orchestrated by Manche with Rentech — the latter helped broker an agreement with market maker Web3Port. Private intelligence firm Groom Lake is conducting the investigation. This was followed by Web3Port reportedly selling the 66 …
    From digital identity to outer space: Projects push crypto use cases

    Stablecoins: Depegging, fraudsters and decentralization
    Opinion by: Merav Ozair, PhD Lately, stablecoins are everywhere — this time around, headed by “traditional” financial institutions. Bank of America and Standard Chartered are considering launching their own stablecoin, joining JPMorgan, which launched its stablecoin, JPM Coin — rebranded as Kinexys Digital Payments — to facilitate transactions with their institutional clients on their blockchain platform, Kinexys (formerly Onyx).  Mastercard plans to bring stablecoins to the mainstream, joining Bleap Finance, a crypto startup. The aim is to enable stablecoins to be spent directly onchain — without conversions or intermediaries — seamlessly integrating blockchain assets with Mastercard’s global payment rails.  In early April 2025, Visa joined the Global Dollar Network (USDG) stablecoin cons…
    Artificial general intelligence (AGI): Can it really think like a human?
    What is AGI? When the lines blur between man and machine, you’re looking at artificial general intelligence (AGI). Unlike its counterpart, artificial narrow intelligence (ANI), which is the use of AI for solving individual problem statements, AGI represents artificial intelligence that can understand, learn and apply knowledge in a way that is indistinguishable from human cognition. AGI is still theoretical, but the prospect of artificial intelligence being able to holistically replace human input and judgment has naturally attracted plenty of interest, with researchers, technologists and academics alike seeking to bring the concept of AGI to reality.  Yet another strand of prevailing research seeks to explore the feasibility and implications of AG…
    Crypto in ‘gamble mindset’ as memecoin mentions hit YTD high: Santiment
    Online discussions about memecoins have hit a year-to-date high, gaining considerable attention after sentiment cooled earlier in the year, according to onchain analytics platform Santiment.  Two weeks ago, discussions around Bitcoin (BTC) and layer-1 protocols peaked during the market volatility brought on by the Trump administration’s sweeping tariffs. However, that’s since shifted to high market cap memecoins, Santiment marketing director Brian Quinlivan said in a May 1 blog post. “Online discussions about these high-risk tokens have proliferated as traders embrace a gamble mindset, rather than a calculated investment approach,” he said. “This is a telltale sign that traders are increasingly investing based solely on speculation and short-term gains,” Quinlivan added. Online discussions…
    Riot Platforms posts Q1 loss, beats revenue estimates
    Bitcoin miner Riot Platforms reported its highest-ever quarterly revenue, but still posted a loss as mining costs have nearly doubled compared to the same period last year amid efforts to expand its facilities. “We achieved a new record for quarterly revenue this quarter, at $161.4 million,” Riot CEO Jason Les said in a May 1 report for its first quarter 2025 earnings. The company just surpassed Wall Street estimates of $159.79 million by 1%. Riot’s Q1 revenue was a 50% jump compared to the same quarter a year ago. Riot blames “halving event” for expenses The firm reported a net loss of $296,367 over Q1, a 240% decrease from the $211,777 net income it posted in the year-ago quarter. Riot said that the average cost to mine Bitcoin (BTC) over the quarter was $43,808, almost 90% more than the…
    US Treasury wants to cut off Huione over ties to crypto crime
    The US Treasury Department is seeking to bar the Cambodia-based Huione Group from accessing the American banking system, accusing the company of helping North Korea’s state-sponsored Lazarus Group launder cryptocurrency. The Treasury’s Financial Crimes Enforcement Network (FinCEN) proposed on May 1 to prohibit US financial institutions from opening or maintaining correspondent or payable-through accounts for or on behalf of the Huione Group. Huione Group has established itself as the “marketplace of choice for malicious cyber actors” like the Lazarus Group, who have “stolen billions of dollars from everyday Americans,” US Treasury Secretary Scott Bessent said in a May 1 statement. “Today’s proposed action will sever Huione Group’s access to correspondent banking, degrading these groups’ ab…
    SEC files to drop crypto promo case against YouTuber Ian Balina
    The US Securities and Exchange Commission has filed to drop another of its crypto lawsuits, this time its unregistered securities sales case against crypto influencer and YouTuber Ian Balina.  The SEC said in a May 1 joint stipulation with Balina to an Austin federal court that it “believes the dismissal of this case is appropriate,” citing the work of the agency’s Crypto Task Force. The agency didn’t give a reason for wanting to dismiss its case, but said its decision “does not necessarily reflect the Commission’s position on any other case.” Balina told Cointelegraph in March that the SEC had informed him it would recommend the court dismiss the case and claimed the agency’s actions were based on a shift in the agency’s priorities. “Obviously, the new administration is pro-crypto,” Balin…
    Sky pitches ousting Maker token to complete upgrade
    Decentralized finance (DeFi) lending platform Sky has pitched a proposal to finalize its upgrade from Maker by replacing its governance token and enabling staking. The proposal, posted on May 1 to Sky’s decentralized autonomous organization (DAO) forum, would see the Sky (SKY) token take over the Maker (MKR) token as the protocol’s governance token. If the DAO accepts, the change would be slated to take place around May 15 to May 19 and downgrading from SKY to MKR would also be disabled. Sky co-founder Rune Christensen said in response to the proposal that it was a “huge milestone,” which he “fully supports,” and laments that allowing users to downgrade from SKY back to MKR has been a “key limiting factor preventing exchanges from adopting SKY.” “With this change, exchanges are likely to m…
    Kraken tells how it spotted North Korean hacker in job interview
    US crypto exchange Kraken has detailed a North Korean hacker’s attempt to infiltrate the organization by applying for a job interview. “What started as a routine hiring process for an engineering role quickly turned into an intelligence-gathering operation,” the company wrote in a May 1 blog post. Kraken said the applicant’s red flags appeared early on in the process when they joined an interview under a name different from what they applied with and “occasionally switched between voices,” apparently being guided through the interview. Rather than immediately rejecting the applicant, Kraken decided to advance them through its hiring process to gather information about the tactics used. International sanctions have effectively cut North Korea off from the rest of the world, and the country’…
    Kraken finalizes NinjaTrader buy as Q1 revenue jumps 19%
    Crypto exchange Kraken has completed its acquisition of the futures trading platform NinjaTrader and reported its first quarter revenues jumped 19% year-on-year to $471.7 million. Kraken said in a May 1 report that its NinjaTrader acquisition would give its US customers access to the traditional derivatives market, aligning with its plans to expand its offerings and be the go-to platform for all types of trading. NinjaTrader is a registered Futures Commission Merchant with the Commodity Futures Trading Commission. Last month, it rolled out trading for over 11,000 stocks and exchange-traded funds to certain US clients. The deal, which Kraken dubbed the largest ever between a crypto and traditional finance firm, allows NinjaTrader to expand to the UK, continental Europe and Australian market…

    Tether posts $1B in Q1 operating profit, $5.6 billion excess in reserves
    Tether, the company behind the world’s largest stablecoin by market capitalization, has released its financials for the first quarter of 2025, disclosing nearly $120 billion in exposure to US Treasurys and over $1 billion in operating profit. According to Tether’s Q1 2025 financial report, the company’s assets include $98.5 billion in direct US Treasury bills, along with over $23 billion in additional exposure through repurchase agreements and other cash-equivalent assets. Excerpt from Tether’s Q1 2025 financial report. Source: Tether According to the announcement, Tether holds $5.6 billion in excess of reserves for its USDt (USDT) stablecoin, down from $7.1 billion in excess from the last quarter of 2024. The stablecoin has a market capitalization of $149 billion as of May 1. “Circulating supply of USDT grew by approximately $7 billion in Q1, with a 46 million increase in user wallets,” it said. The company's excess capital continues to fund strategic investments, with more than $2 billion allocated in renewable energy, artificial intelligence, peer-to-peer communications, and data infrastructure.  The stablecoin market is broadly dominated by tokens pegged to the US dollar, with USDT and Circle’s USDC holding a combined 87% share. According to the US Treasury’s Q1 2025 report, the market cap for dollar-backed stablecoins is poised to reach $2 trillion by 2028. European Union officials have recently raised concerns about the risks of overreliance on dollar-pegged stablecoins. According to the Bank of Italy, disruptions in the stablecoins market or the underlying bonds could have “repercussions for other parts of the global financial system.” Magazine: Crypto wanted to overthrow banks, now it’s becoming them in stablecoin fight
    Crypto ‘decoupling’ story ends as stocks follow Bitcoin’s rally

The total crypto market capitalization rose 8.5% since March.

    The crypto trends Animoca Brands is eyeing this year — Token2049
    Animoca Brands is looking at trends in real-world tokenized assets, AI projects, and the gaming sector to invest in and develop, according to Omar Elissar, the company's managing director for the Middle East and the head of Global Strategic Partnerships. In an interview with Cointelegraph's Sam Bourgi at Token2049, Elissar said that stablecoins, real-world asset tokenization, the intersection between AI and crypto, alternative use cases such as decentralized science, and Web3 gaming were all niches the company is exploring. Gaming is "part of our DNA," the executive said before reflecting on the current state of the Web3 gaming industry: "It's gone quiet for some time in terms of less PR, but there's been building in the background. Recently, there have been a few games that have come out …
    Australian election will bring pro-crypto laws either way
    Despite reports in February suggesting that 2 million pro-crypto voters could decide the outcome of this week’s Australian Federal Election, crypto has barely rated a mention during the campaign. “I think it’s a missed opportunity,” Independent Reserve founder Adrian Przelozny told Cointelegraph. “Neither side has made crypto a headline issue because they’re wary of polarizing voters or sounding too niche.” But the good news is that after more than a decade of inaction, both the ruling Australian Labor Party (ALP) and the opposition Liberal Party are promising to enact crypto regulations developed in consultation with the industry. In April, Shadow Treasurer Angus Taylor promised to release draft crypto regulations within the first 100 days after taking office, while the Treasury itself h…
    Mango Markets exploiter sentenced to over 4 years on child abuse material charges
    Avraham Eisenberg was sentenced to more than four years in prison on child sexual abuse material charges, unrelated to his role in the 2022 exploit that drained the decentralized exchange Mango Markets of roughly $100 million. According to reporting from Inner City Press, a judge sentenced Eisenberg to 52 months in prison at a May 1 hearing in the US District Court for the Southern District of New York. The case was filed in April 2024 after Eisenberg’s 2023 indictment on fraud for the Mango Markets exploit. Eisenberg was initially scheduled to be sentenced in July 2024 following his guilty plea on the child porn charge. In May 2024, the judge suggested the sentencing for both cases would occur simultaneously in a consolidated proceeding. However, as of May 1, the fraud sentencing remains …
    Strategy touts 14% YTD Bitcoin yield in Q1 earnings print, misses estimates
    Update (May 1, 11:35 pm UTC): This article has been updated to add Strategy’s revenue, net loss and analyst estimates. Michael Saylor's Bitcoin-buying firm Strategy, formerly MicroStrategy, has reported earning a year-to-date yield of 13.7% on its Bitcoin holdings as it missed Wall Street's first-quarter estimates. The company said in its May 1 earnings statement that its year-to-date Bitcoin (BTC) yield equates to a gain of more than 61,000 BTC, worth approximately $5.8 billion. Bitcoin yield and gain are unofficial accounting metrics Strategy uses to benchmark the success of its BTC buys.  Strategy’s chief financial officer, Andrew Kang, said it would increase its Bitcoin yield target for this year to 25% and its Bitcoin gain target to $15 billion. It comes as Strategy missed top and bot…
    US lawmaker proposes crypto ATMs in federal buildings

In a May 1 letter to Stephen Ehikian, the acting administrator of the General Services Administration (GSA) — the entity responsible for managing the US government’s properties — Rep. Lance Gooden claimed that introducing crypto ATMs to federal buildings would serve as an “educational resource” and reflect advances in financial technology. He requested that the GSA begin exploring the necessary guidelines and regulations needed to install such ATMs in government-controlled properties across the US, citing alignment with President Donald Trump’s goals.

    Institutional Bitcoin buying may soon price out retail — LONGITUDE panel
    Retail investors are running out of time to accumulate Bitcoin as institutional adoption accelerates, according to Sergej Kunz, co-founder of exchange aggregator 1inch. Bitcoin (BTC) is evolving into an alternative reserve currency, propelling institutional demand and potentially pricing out retail investors, Kunz said during Cointelegraph's LONGITUDE event in Dubai.  "Every retail user should be thinking about getting at least one Bitcoin — very soon they won’t be able to afford it,” Kunz said.  If the United States starts buying Bitcoin for a strategic reserve, even smaller countries may soon struggle to acquire the cryptocurrency, he added. "I’m pretty sure we’ll soon see countries battling over who owns more Bitcoin. The US will start.” Bitcoin demand has accelerated since US Presiden…
    Bitcoin trader says BTC’s cycle top in $125K to $150K range if certain conditions are met

Bitcoin (BTC) price jumped to new quarterly highs at $96,700 on May 1, a day after the US GDP contracted -0.3% for the first time since Q2 2022. Amid heightened economic concerns, the probability of a Federal Reserve interest rate cut rose to 62.8% for the June 18 Federal Reserve meeting.

    Tether CEO defends decision to skip MiCA registration for USDT
    Paolo Ardoino, CEO of stablecoin issuer Tether, addressed criticism over the company's decision not to seek registration under the European Union’s Markets in Crypto-Assets (MiCA) framework, arguing that the regulations were risky for stablecoins. Speaking to Cointelegraph at the Token2049 conference in Dubai, Ardoino reiterated that Tether had no plans to apply for its US dollar-pegged stablecoin USDt — the largest by market capitalization — to be compliant under MiCA in European countries, potentially forcing exchanges to delist the stablecoin. He added that though crypto firms had to follow regulations, there was a “fear of compliance” among companies in the EU. “[...] MiCA license is very dangerous when it comes to stablecoins, and I believe that is even more dangerous for the small, m…

    Devs introduce Ethereum R1 layer-2 scaling solution
    A group of developers within the Ethereum ecosystem, operating independently of the Ethereum Foundation, have announced Ethereum R1 — a layer-2 (L2) scaling solution for the Ethereum network that does not include a native token. According to the announcement, the project relies entirely on donations, does not have venture funding, and does not have any pre-mined token allocations or a governance token. The project's team wrote in a May 1 X post: "General-purpose L2s should be commodities — simple, replaceable, and free from centralized dependencies or risky governance. Ethereum R1 is our answer to that call — the rollup grounded in credible neutrality, decentralization, and censorship resistance." "Most L2s today are acting more like new L1s than an Ethereum scaling solution — private allo…

In September 2015, the New York Department of Financial Services (NYDFS) issued its first BitLicense to Circle Internet Financial, enabling the company to conduct digital currency business activity in the state. Ripple Markets received the second BitLicense in 2016. Circle and Ripple went on to become giant players in the global cryptocurrency and stablecoin industry. Today, the NYDFS regulates one of the largest pools of crypto firms in the world, and it is often cited as the gold standard…

    The case for enterprise-grade custody solutions
    Opinion by: Vikash Singh, Principal Investor at Stillmark The Bybit hack resulted in the largest loss of funds to cyber hackers by a cryptocurrency exchange in history. It served as a wake-up call for those complacent about the state of security threats in the digital assets space. Everyone must learn the lesson from this heist — enterprise-grade custody solutions require tech to be accompanied by transparency. Unlike many previous incidents, this loss of funds was not due to a faulty smart contract, lost/mismanaged keys or deliberate mismanagement or rehypothecation of user funds, but rather a sophisticated social engineering attack that exploited vulnerabilities in operational security.  This hack differs from earlier eras because it happened to a major global exchange that takes securit…
    Bitcoin to $1M by 2029 fueled by ETF and gov’t demand — Bitwise exec
    Bitcoin’s expanding institutional adoption may provide the “structural” inflows necessary to surpass gold’s market capitalization and push its price beyond $1 million by 2029, according to Bitwise’s head of European research, André Dragosch. “Our in-house prediction is $1 million by 2029.

    Bitcoin yield demand booming as institutions seek liquidity — Solv CEO
    The demand for yield-generating strategies around Bitcoin (BTC) is surging, especially from firms seeking liquidity without liquidating their BTC, according to Ryan Chow, co-founder and CEO of Solv Protocol. During a fireside chat at the Token2049 conference in Dubai on May 1, Chow said institutional interest in Bitcoin yield products has grown exponentially over the past few years. Initially, generating Bitcoin yield was nearly impossible. However, recent innovations like staking via proof-of-stake (PoS) protocols and delta-neutral trading strategies have made this possible. Layer-1 and layer-2 advancements, such as Babylon, have made these strategies more viable. Babylon allows BTC holders to earn yield on their assets, which are used to provide security and liquidity for PoS networks. “…
    Ethereum to simplify crosschain transactions with new token standards
    Ethereum developers are working to improve blockchain interoperability with two new token standards: ERC-7930 and ERC-7828. “There’s no standard way for wallets, apps, or protocols to interpret or display this information,” decentralized finance (DeFi) ecosystem development organization Wonderland wrote in a May 1 X post. Wallets, decentralized applications (DApps), block explorers and smart contracts follow different rules. “The result? A messy, inconsistent experience that breaks cross-chain UX,“ Wonderland stated.

    $21B tokenized RWA market doubtful, institutions uninterested — Plume CEO
    Amid the intensifying global race to tokenize real-world assets, the market is still too nascent for institutional adoption, according to Chris Yin, the co-founder and CEO of Galaxy-backed RWA platform Plume. Institutional capital is yet to enter the RWA market, and it will take some time for institutions to see its value, Yin told Cointelegraph on the sidelines of Token2049 in Dubai. “These things move incredibly slowly, you have to show value, you have to show adoption first,” Yin said, comparing RWA’s currently developing stages with the early days of Bitcoin (BTC) and stablecoins. “Only now, 10 years later, are they beginning to think about using the stablecoin. The same thing is going to happen in tokenized assets or tokenization,” Yin said. Tokenized RWAs are far smaller than $21 bil…
    Google subpoena scam: What it looks like and how to avoid it
    What is a Google subpoena scam? The Google subpoena scam is a type of phishing attack where fraudsters impersonate Google to create a false sense of urgency and fear.  Typically, you will receive an email that appears to come from no-reply@google.com, claiming to inform you of a subpoena, a formal legal request. The email will often have a subject line like “Security Alert” or “Notice of Subpoena,” making it seem urgent and legitimate. These scammers prey on your natural concern about legal matters and data privacy, hoping to trigger a reaction. Inside the email, the scammers falsely claim that Google has been served with a subpoena requiring the company to turn over your account data, such as emails, documents or search history. The email will the…

    Key takeaways: Bitcoin holds $95,000 as Fed rate cut odds rise to 60% for June 18 and the US economy slumps. Breaking $95,000 could push BTC’s price toward $100,000, while dropping below $93,000 may bring the $84,000 back into the picture.

    XRP traders predict new all-time highs as ETF approval odds rise to 85%
    Key takeaways: XRP ETF approval odds rise to 85% following a SEC leadership change. Analysts predict XRP could rise to new all-time highs again in 2025. XRP price dropped by 5% over the past 24 hours as US GDP data showed a shrinking economy. However, a strengthening market structure and investors’ growing hope for a spot XRP ETF approval in the United States suggest that the altcoin might revisit its April peak at $2.36 in the short term.  XRP/USD daily chart.

    Robinhood beats Q1 estimates despite revenue, crypto trading dip
    Trading platform Robinhood has still managed to beat Wall Street estimates as its first-quarter revenues fell and its crypto trading volume cooled from a record high in Q4. Robinhood’s Q1 results shared on April 30 show revenues fell 8.6% from the previous quarter to $927 million, topping Zacks analyst estimates by 3.16%. The company’s crypto revenue plummeted nearly 30% quarter-on-quarter to $252 million from the firm’s record-setting Q4 2024.   The drop could be partly attributed to the Trump administration’s tariffs, which triggered an 18% fall in the crypto market cap over the quarter. Crypto trading volume on Robinhood also fell 35% over Q1 compared to the fourth quarter of 2024, which the firm attributed to a 10% drop in customer trades placed and a 27% fall in average notional volum…
    Solana futures open interest nears all-time high — Will SOL price follow?
    Key points: Solana held the $140 support level for a week, a first in more than two months, highlighting traders’ growing confidence. SOL futures open interest hit $5.75 billion on April 30, showing strong institutional interest. With rising DEX volumes and a $9.5 billion TVL, SOL could rally to $200 before a potential spot ETF approval on Oct. 10. Solana’s native token, SOL (SOL), fell 4% between April 29 and April 30 after failing to sustain the $150 level. Despite this short-term decline, traders seem more confident as the $140 support remained intact for a whole week, an outcome that hadn’t happened in over two months.  As demand for leveraged SOL positions reached near record highs on April 30, traders are now reconsidering the chances of a SOL rally above $200.

    Mastering Conditional Rendering in React
    What is Conditional Rendering? In React, conditional rendering allows you to dynamically render different UI components based on certain conditions. You can use JavaScript logic such as if statements, the ternary operator (? :), the logical AND (&&), or assign JSX to variables. Using if Statements The simplest way to conditionally render components is by using if statements inside a function component. Example: function AlertMessage({ show }) { if (!show) { return null; } return This is an alert message! ; } export default function App() { return ; } In this example, if show is false, the component returns null and nothing is rendered. Using Ternary Operator (? :) The ternary operator is a compact way to return di…  ( 4 min )

    Cracking MySQL Performance: What is Indexing and Why It Matters
    🚀 Introduction Have you ever run a SQL query that just took forever and wondered, "Why is this so slow?" You're not alone. Databases are fast until they're not. And one of the simplest, yet most powerful performance tricks in SQL is indexing. What indexing really means in MySQL Why indexes are performance game changers The exact results of an experiment we ran on 80,000+ records in MySQL 5.7 on a local setup (8GB RAM, SSD) When indexing helps and when it doesn't Let's dive in. Think of an index like a book's table of contents. If you need Chapter 8, you don't flip through every single page you jump straight to it. That's what MySQL does with an index.

    Welcome to My First Startup Journey
    Hi everyone, After doing my first job as a frontend engineer in a startup for an year, I left my job. Their are multiple reasons for it, but that was the story of another time. After that I decided to not pursue the tech career and start my chocolate factory - HAKI, a chocolate spread idea that crossed my mind. If anyone is thinking, why making a chocolate spread would be so hard, like I thought initially, my 1st two variants caught fungus within a week. Long time, messaging a hundred people for advice and many failed attempts, now I'm here finally — with the most delicious recipe made using clean, wholesome ingredients to keep it truly healthy. Ahh and please follow Haki on @eathaki_ to know more about it. We're still on the lookout for a graphic designer who's excited to help build HAKI — feel free to drop me an email if someone comes to mind. Thank you so much for reading it till here 😊 Also, if there's a better place to share this, please let me know.  ( 3 min )

Instead of meticulously writing out code line by line, developers describe what they want the software to do, and AI models translate these descriptions into executable code. This method emphasizes clarity of thought and design over manual co…  ( 4 min )
    Re: Will AI Take My Job? A Coder's Reality Check
    I originally posted this post on my blog. Anita asked if AI, given all the hype, will take her job. Here: Will AI Take My Job? Anita Olsen ・ Apr 22 #discuss #ai Sure, we code daily and AI shines at spitting out code. But most of our work is balancing expectations and handling risk. Apart from coding, we as coders have to deal with: Inter-team planning Brainstorming sessions Putting late sprints back on track Designing requirements and user stories Decomposing a full project into milestones Scoping tasks with Product people Reviewing architecture designs Negotiating deadlines Talking to clients And that involves a lot of human interaction. It shouldn't surprise anyone that a coder will spend more time in meetings than coding on a normal day. And AI can't replace that human interaction yet. But sure, our job as coders will change. Even if we're skeptical about AI, we can't ignore it. We can only assume AI will generate code faster and cheaper than any of us. We have to adapt. We won't be code monkeys anymore, cracking lines of code in exchange for bananas. AI will handle that. And if AI will change everything, let it at least kill dumb SCRUM ceremonies.

    Ethereum bulls show interest as traders’ confidence in ETH’s $1.8K level improves
    Key takeaways: Traders remain cautious about ETH’s price action, but optimistic sentiment is beginning to return. The May 7, Ethereum Pectra upgrade could boost investor sentiment, but ETH’s price action shows investors are still hesitant to open new positions. Ether (ETH) has been trading below $1,900 since March, leading investors to question whether the failed attempt to reclaim $4,000 in December 2024 signaled the end of an era for the leading altcoin. Concerns continue to mount as derivatives market data shows that professional traders remain cautious about ETH’s price outlook.  ETH monthly futures should trade at a premium of 5% or more compared to spot markets to compensate for the longer settlement period, but this indicator has held below the neutral threshold. Ether 3-month fu…
    ‘Huge Shift’ in crypto firms’ compliance mindset, says Elliptic co-founder
    The crypto industry has seen a significant shift toward regulatory compliance since its early days, according to James Smith, co-founder of Elliptic, a crypto compliance firm established in 2013. “In the early days, only a few companies approached compliance in a serious way,” Smith told Cointelegraph at the Token2049 event. “Coinbase was our first customer — they knew from the start that they wanted to build their business that way. But for most others, it just wasn’t a major priority.”Elliptic co-founder James Smith at Token2049.

    'To have freedom of money, you have to have freedom of speech' — CZ
    Binance co-founder and former CEO Changpeng “CZ” Zhao took the stage at Token2049 in Dubai, United Arab Emirates (UAE), where he told the audience that his investment in social media platform X was aimed at protecting freedom of speech. The former Binance executive joined a fireside panel with macroeconomic analyst Raoul Pal to discuss the rationale behind his 2022 investment in X and artificial intelligence. Zhao said: "I think freedom of money is important, but to have freedom of money, you have to have freedom of speech. Freedom of speech is kind of the bottom line. If you don't have that, nothing — no other freedom — works."   "So, when we invested in Twitter back then, it was based on that philosophy," Zhao continued. The former Binance CEO also criticized Europe's crypto policies, ch…
    Bitcoin rebounds from bearish US GDP data as dip buyers push BTC price back toward $95K
    Key takeaways: Bitcoin bulls are attacking the $95,000 level again after today’s brief US GDP-induced sell-off. Traders are semi-agnostic to negative US economic data as they expect the Federal Reserve to resume easing and rate cuts at some point in the future. Bitcoin (BTC) price knocks on the door of $95,000 after starting the NY trading session with a slight sell-off to $92,910 following alarm-raising US GDP data, which showed the economy shrank in Q1 2025. The move mirrors a similar recovery seen in the DOW and S&P 500, which bounced 0.35% and 0.15% respectively at the closing bell.  The quick recovery in Bitcoin price highlights the strong bid by a variety of market participants, and it lines up with the view that the April 30 GDP data could be a one-off event resulting from bus…
    Bloomberg Intelligence boosts Solana ETF approval odds to 90%
    Bloomberg Intelligence has boosted its estimated odds of US regulators approving a Solana exchange-traded fund (ETF) in 2025 to 90%, according to an April 30 post on the X platform.  The company also set more favorable chances of approval for other altcoin ETFs, including proposed funds holding XRP (XRP) and Dogecoin (DOGE), Bloomberg analyst Eric Balchunas said in an X post.  The estimates reflect an improved outlook from Bloomberg analysts.

    Coinbase files brief with US Supreme Court in support of taxpayers' privacy
    US-based cryptocurrency exchange Coinbase has filed an amicus brief in the country’s Supreme Court in support of a taxpayer fighting the Internal Revenue Service (IRS) gaining access to his data from a digital asset platform. In an April 30 filing in the Supreme Court of the United States (SCOTUS), lawyers for Coinbase argued that a First Circuit Court of Appeals decision set a “dangerous precedent” for crypto users, potentially allowing the government to “trace users’ every crypto transaction in the past and monitor every crypto transaction in the future.” The appeal to the Supreme Court stemmed from petitioner James Harper, a Coinbase user, who took legal action against the IRS after the crypto exchange was forced to turn over transaction data to the government using a sweeping “John Doe…

    Ethereum Pectra upgrade goes live next week — Will ETH price rally?
    Key takeaways: ETH price has underperformed its peers during the current bull market, but gas sponsorship could lure developers and traders back to the network. Ethereum’s upcoming Pectra upgrade promises to improve staking efficiency, potentially increasing demand for ETH. Data suggests ETH price bottomed. Will the Pectra narrative reignite bullish momentum? Since 2024, ETH (ETH) has been more of a meme than a market mover. Unlike most of its rivals, ETH still hasn’t reclaimed its all-time high of $4,870 from November 2021, and it regularly underperforms even in the weak altcoin market. Currently, ETH trades at $1,813, down 56% from its local peak in December 2024. Despite the dismal price action, dismissing Ethereum as a relic may be premature. The network continues to evolve, and th…

    Price predictions 4/30: BTC, ETH, XRP, BNB, SOL, DOGE, ADA, SUI, LINK, AVAX
    Key points: Bitcoin’s 7-day volatility is the lowest in 563 days, signaling an impending range expansion. Bitcoin’s breakout above $95,000 could swiftly take it to $100,000 and above. Although the probability is low, traders should remain cautious about a pullback in the near term. Bitcoin (BTC) has been trading in a tight consolidation near the $95,000 level for several days. K33 Research head of research Vetle Lunde said in a post on X that Bitcoin’s 7-day volatility has hit a 563-day low. A range expansion usually follows a low-volatility period. Although it is difficult to predict the direction of the breakout, a tight consolidation just below a crucial resistance increases the likelihood of an upside rally. Several analysts are also optimistic that Bitcoin’s break will occur to th…
    Global demand grows for non-dollar stablecoins, says Fireblocks exec
    Governments outside the US, including Singapore, are increasingly interested in stablecoins not tied to the US dollar, despite their currently limited liquidity, Fireblocks director of policy Dea Markova told Cointelegraph at Token2049. In an exclusive interview, Markova described the competition with dollar-pegged stablecoins as “all about sovereignty.” She compared the situation to earlier tensions between governments and US payment giants like Visa and Mastercard. “Now we’re seeing the same dynamic with stablecoins — on a smaller scale for now — but they’re definitely emerging as a new arena for sovereign concerns,” she said. According to Markova, dollar-pegged stablecoins operating in the European Union are already "having a massive headache," particularly from central banks. "Even tho…

    Bitcoin drops under $93K after US GDP data shows shrinking economy, raising recession alarms
    Key points:  US GDP shrank in Q1, raising recession alarms while also prompting calls for Fed rate cuts. Bitcoin dropped to $92,910 as GDP figures were released, but sustained buy-side demand could provide support.  Today’s crypto derisking is likely transitory; market fundamentals remain strong. Bitcoin (BTC) price took an abrupt tumble as data showed the US gross domestic product (GDP) retracting by 0.3% in Q1, raising alarms among analysts anticipating a recession. Following the news, BTC price dropped to an intra-day low of $92,910, while the DOW and S&P 500 fell by 1% and 1.3% respectively.  While the GDP figures are shocking at face value, CNBC pointed out that the drop was primarily due to “a surge in imports ahead of President Donald Trump’s tariffs.” Imports are subtracted fro…
    EU digital product passports won’t solve food fraud, but blockchain can
    Opinion by: Fraser Edwards, co-founder and CEO, Cheqd Brutal honesty has its place, especially when confronting discomfort, so here’s one that can’t be sweetened with honey: 96% of imported honey in the UK is fake! Tests found that 24 of 25 jars were suspicious or didn’t meet regulatory standards.  Self-sovereign identity (SSI) can fix this.  The UK Food Standards Agency and the European Commission both urge reform to tackle this concern by creating a robust traceability database within supply chain networks to ensure consumer transparency and trust.

    $330M Bitcoin social engineering theft victim is elderly US citizen
    An elderly US individual is reportedly the victim of a devastating $330 million Bitcoin heist, now ranked as the fifth-largest crypto hack in history. The attacker used advanced social engineering tactics to gain access to the victim’s wallet, onchain investigator ZachXBT said in an April 30 update on X. The hack took place on April 28, 2025, when ZachXBT flagged a suspicious transfer involving 3,520 Bitcoin (BTC), valued at $330.7 million. Following the transfer, the stolen stash was quickly laundered through over six instant exchanges and swapped into privacy-focused cryptocurrency Monero (XMR).

    The open source debate: Is crypto losing its soul?
    Crypto was born from an open-source ethos, where code was shared publicly, accessible for review and shaped by community contributions. Transparency and verifiability are foundational principles that enable trust in Bitcoin. But as the space matured, some disadvantages of open source surfaced. Innovative smart contract platforms and decentralized finance (DeFi) applications were forked to create direct competitors — from the wave of Uniswap clones to Ethereum forks — which prioritized speed and lower fees over decentralization. As a result, some projects opted for closed-source development to protect proprietary designs and reduce the risk of exploits, hoping to delay or deter malicious actors by making the code harder to analyze. This approach is often criticized as “security through obsc…
    FTX sues NFT Stars and Kurosemi in push to recover tokens
    Bankrupt crypto exchange FTX has filed lawsuits against the non-fungible token marketplace NFT Stars and the blockchain gaming firm Kurosemi, which operates as Delysium, accusing them of withholding tokens they owed. The lawsuits, both filed in the Delaware bankruptcy court, alleged that NFT Stars and Delysium failed to deliver all the tokens paid for by FTX despite repeated attempts to resolve the matter. FTX claimed in an April 28 statement that it made “numerous unanswered attempts” to engage with both firms, and it would be “contacting numerous other token and coin issuers regarding FTX assets and will be filing additional suits against non-responsive parties.” Source: FTX As part of the complaint against Delysium, FTX claimed its defunct trading arm, Alameda Research, paid $1 million …
    BlackRock files to create digital shares tracking one of its money market funds
    Asset manager BlackRock has filed to create digital ledger technology shares from one of the firm’s money market funds, which will leverage blockchain technology to maintain a mirror record of share ownership for investors. The DLT shares will track BlackRock’s BLF Treasury Trust Fund (TTTXX), which may only be purchased from BlackRock Advisors and The Bank of New York Mellon (BNY), the firm said in its April 29 Form N-1A filing with the Securities and Exchange Commission. The money market fund holds over $150 million worth of assets, invested almost entirely in US Treasury bills and cash. BlackRock said that the shares “are expected to be purchased and held through BNY, which intends to use blockchain technology to maintain a mirror record of share ownership for its customers.” Unlike the…
    US Treasury’s OFAC can’t restore Tornado Cash sanctions, judge rules
    The US Treasury Department’s Office of Foreign Assets Control can’t restore or reimpose sanctions against the crypto mixing service Tornado Cash, a US federal court has ruled. Austin federal court judge Robert Pitman said in an April 28 judgment that OFAC’s sanctions on Tornado Cash were unlawful and that the agency was “permanently enjoined from enforcing” sanctions. Tornado Cash users led by Joseph Van Loon had sued the Treasury, arguing that OFAC’s addition of the platform’s smart contract addresses to its Specially Designated Nationals and Blocked Persons (SDN) list was “not in accordance with law.”  OFAC had sanctioned Tornado Cash in August 2022, accusing the protocol of helping launder crypto stolen by the North Korean hacking collective, the Lazarus Group. The agency dropped the pl…
    Strategy’s Bitcoin buys should be ‘super careless’ to pump price — Exec
    Key takeaways: Richard Byworth says Michael Saylor’s Strategy could ramp up its Bitcoin buys by acquiring cash-rich companies and converting their cash into Bitcoin. He says that Strategy should consider accelerating purchases as the Bitcoin supply on exchanges continues to decline. Byworth argues that aggressively increasing Bitcoin holdings would boost Strategy’s mNAV, benefiting shareholders. Michael Saylor’s Strategy should take a more aggressive approach to buying Bitcoin by acquiring companies to use their cash holdings to fund purchases and do away with over-the-counter buys, a crypto executive says. “Saylor’s strategy so far has been the right one,” Syz Capital partner and Jan3 adviser Richard Byworth said on an April 29 podcast. Strategy should try “super aggressive” buying Ho…
    Australia’s finance watchdog to crack down on dormant crypto exchanges
    Australia’s financial intelligence agency has told inactive registered crypto exchanges to withdraw their registrations or risk having them canceled over fears that the dormant firms could be used for scams. There are currently 427 crypto exchanges registered with the Australian Transaction Reports and Analysis Centre (AUSTRAC), but the agency said on April 29 that it suspects a significant number are inactive and possibly vulnerable to being bought and co-opted by criminals. The agency is contacting any so-called digital currency exchanges (DCEs) that appear to no longer be trading, and AUSTRAC CEO Brendan Thomas said they’ll be told to “use it or lose it.” “Businesses registered with AUSTRAC are required to keep their details up to date; this includes details about services that are no l…
    Ledger scammers are sending letters to steal seed phrases
    Scammers are mailing physical letters to the owners of Ledger crypto hardware wallets asking them to validate their private seed phrases in a bid to access the wallets to clean them out. In an April 29 X post, tech commentator Jacob Canfield shared a scam letter sent to his home via post that appeared to be from Ledger claiming he needed to immediately perform a “critical security update” on his device.  The letter, which uses Ledger’s logo, business address, and a reference number to feign legitimacy, asks to scan a QR code and enter the wallet’s private recovery phrase under the guise of validating the device. The letter threatens that “failure to complete this mandatory validation process may result in restricted access to your wallet and funds.” Source: Jacob Canfield A seed phrase, or…

    Labor pain, crypto gain — How weak JOLTS data sets path for Bitcoin price to rally
    Key points: Weak labor and consumer data often precede Bitcoin rallies, leading some analysts to anticipate future economic stimulus programs. Job openings fell to 7.2 million in March versus the 7.5 million forecast and consumer confidence hit its lowest level since January 2021. If past patterns hold, Bitcoin could rally by mid-July and possibly reach $140,000 by October 2025. Macroeconomic conditions have long been seen as a major influence on cryptocurrency prices. Generally, Bitcoin (BTC) and altcoins perform poorly when investors fear that employment and consumer data are weakening.  According to a US Labor Department JOLTS report released on April 29, job openings in March approached their lowest levels in four years.
